LXD 4.10 リリースのお知らせ¶

8th of January 2021

はじめに ¶

LXD チームは LXD 4.10 のリリースをお知らせできることにとてもワクワクしています!

このリリースは軽めのリリースです。それは、LXD チームは 12 月 18 日から 1 月 4 日までお休みをいただいていたためです。しかし、多くのバグフィックスといくつか新しい改良が行われました。

Enjoy!

新機能とハイライト ¶

ネットワークの状態表示内の VLAN 情報 ¶

ボンディングやブリッジの情報のように、新たに VLAN 構造をネットワーク状態のエンドポイントに追加しました。これは下位デバイスとインターフェースの VLAN ID を表示します。

root@abydos:~# lxc query /1.0/networks/bond-sw01.100/state
{
    "addresses": [],
    "bond": null,
    "bridge": null,
    "counters": {
        "bytes_received": 213651991756,
        "bytes_sent": 42453202,
        "packets_received": 97607519,
        "packets_sent": 431818
    },
    "hwaddr": "0a:0f:7c:6e:db:d9",
    "mtu": 1500,
    "state": "up",
    "type": "broadcast",
    "vlan": {
        "lower_device": "bond-sw01",
        "vid": 100
    }
}

VM のプロキシーデバイスのサポート（NAT のみ） ¶

仮想マシンで proxy デバイスが使えるようになりました。 これは NAT モード（nat=true）でのみ機能するので、両サイドで同じプロトコルを使う必要があります。

ブリッジポートの隔離 ¶

ブリッジネットワークインターフェースに新たに security.port_isolation を追加しました。これによりインターフェース間の通信を制限できるようになりました。

イメージプロパティに関する新しいサブコマンド ¶

イメージプロパティへのアクセス、設定、解除のために、新たに lxc image コマンドに 3 つの新しいサブコマンドを追加しました。

• lxc image get-property
• lxc image set-property
• lxc image unset-property

例 :

stgraber@castiana:~$ lxc image get-property 305db7054652 os
Ubuntu
stgraber@castiana:~$ lxc image set-property 305db7054652 foo bar
stgraber@castiana:~$ lxc image get-property 305db7054652 foo
bar
stgraber@castiana:~$ lxc image unset-property 305db7054652 foo
stgraber@castiana:~$

VM 内のマルチキューネットワーキング ¶

仮想マシン上のネットワークインターフェースは、仮想マシンに割り当てられた仮想 CPU の数と一致するように RX キューおよび TX キューの数を自動的に設定するようになりました。

これにより、高速ネットワークを扱う場合には特にネットワークパフォーマンスが大幅に向上するはずです。

LXD 4.9 リリースのお知らせ¶

11th of December 2020

はじめに ¶

LXD チームは LXD 4.9 のリリースをお知らせできることにとてもワクワクしています!

このリリースには、オースティンにあるテキサス大学の学生からの次のコントリビューションが含まれています:

• プロジェクトに対する limits.instances 設定
• サーバー情報に qemu ドライバーとバージョンを表示
• リソース API 内に IOMMU グループを表示
• サーバー設定内の user. 設定

それに加えて、GPU の媒介（mediated）デバイスのパススルーが使えるようになり、ライフサイクルイベントにいくつか改良をほどこし、リソース API へいくつか追加を行い、zstd 圧縮が使えるようになり、OVN ユーザーのための様々な新しいオプションを追加しています。

Enjoy!

新機能とハイライト ¶

仮想マシンに対する GPU 媒介デバイス ¶

LXDで、媒介デバイス（mediated device）をサポートしているGPUから媒介デバイスを割り当てることができるようになり、それを仮想マシンにアタッチできるようになりました。

これは、新たに導入された gpu のための設定 gputype によって行います。設定値は現時点では次の値をサポートしています:

• physical （全 GPU。従来のデフォルトの動作）
• mdev プロファイルを指定するための追加の mdev キーと組み合わせて使います

lxc info --resources でも mdev プロファイルが表示されるようになりました。

GPU:
  NUMA node: 0
  Vendor: Intel Corporation (8086)
  Product: HD Graphics 620 (5916)
  PCI address: 0000:00:02.0
  Driver: i915 (5.8.0-29-generic)
  DRM:
    ID: 0
    Card: card0 (226:0)
    Control: controlD64 (226:0)
    Render: renderD128 (226:128)
  Mdev profiles:
    - i915-GVTg_V5_4 (1 available)
        low_gm_size: 128MB
        high_gm_size: 512MB
        fence: 4
        resolution: 1920x1200
        weight: 4
    - i915-GVTg_V5_8 (2 available)
        low_gm_size: 64MB
        high_gm_size: 384MB
        fence: 4
        resolution: 1024x768
        weight: 2

PCI デバイスの IOMMU グループ ¶

リソース API（/1.0/resources）の PCI セクションのデバイスそれぞれには、IOMMU グループの ID を示す iommu_group が表示されるようになりました。

これは、パススルーネットワークや GPU デバイスを仮想マシンに追加する前に IOMMU トポロジーを確認するのにとても役立ちます。

stgraber@castiana:~$ lxc query /1.0/resources | jq .pci.devices[-1]
{
  "driver": "xhci_hcd",
  "driver_version": "5.8.0-29-generic",
  "iommu_group": 16,
  "numa_node": 0,
  "pci_address": "0000:3c:00.0",
  "product": "JHL6540 Thunderbolt 3 USB Controller (C step) [Alpine Ridge 4C 2016]",
  "product_id": "15d4",
  "vendor": "Intel Corporation",
  "vendor_id": "8086"
}

サーバ環境情報内の QEMU バージョン表示 ¶

次の lxc info の実行例に表示されているように、システムの QEMU のバージョンが driver と driver_version に含まれるようになりました。

stgraber@castiana:~$ lxc info | grep " driver"
  driver: lxc | qemu
  driver_version: 4.0.0 (devel) | 5.2.0

ライフサイクルイベントの改良 ¶

ライフサイクルイベントを実装しなおして拡張しました。

現時点の完全なリストは次のとおりです:

• instance-created
• instance-renamed
• instance-deleted
• instance-updated
• instance-started
• instance-stopped
• instance-shutdown
• instance-restarted
• instance-paused
• instance-resumed
• instance-snapshot-create
• instance-snapshot-renamed
• instance-snapshot-deleted
• instance-restored
• instance-backup-created (new)
• instance-backup-renamed (new)
• instance-backup-deleted (new)
• network-created (new)
• network-updated (new)
• network-renamed (new)
• network-deleted (new)

お気づきのように、従来の container と virtual-machine のプレフィックスが混じった状態ではなく、一貫して instance が使われるようになりました。バックアップのためにイベントが不足していた問題がいくつか解消され、ネットワークイベントの初期カバレッジも追加されました。

user. キーがすべてのオブジェクトで使用可能に¶

このリリースで、設定を保持するすべての LXD オブジェクト内で user. キーが使えるようになりました。これらのキーは、追加のコンテキストを保存する必要がある外部のオーケストレーションシステムやモニタリングシステムで特に役に立ちます。

最近、これらのキーはサーバ自身を除くすべてのオブジェクトで使えましたが、これが解決されました。

stgraber@castiana:~$ lxc config set user.foo bar
stgraber@castiana:~$ lxc config get user.foo
bar

USB・ネットワークリソースの usb_address と pci_address プロパティ ¶

usb_address フィールドが、新たにソース API 内のネットワークとストレージデバイスの両方に追加されました。USB 接続がなされた際、デバイスの <bus>:<dev> で表示されます。これは PCI デバイスの pci_address にとても似ています。

同時に、ストレージデバイスになかった pci_address フィールドも追加されました。

stgraber@castiana:~$ lxc query /1.0/resources | jq .storage.disks[-1]
{
  "block_size": 512,
  "device": "8:0",
  "device_id": "usb-Kingston_DataTraveler_3.0_08606E6B6612BE50D7168119-0:0",
  "device_path": "pci-0000:00:14.0-usb-0:1:1.0-scsi-0:0:0:0",
  "firmware_version": "PMAP",
  "id": "sda",
  "model": "DataTraveler 3.0",
  "numa_node": 0,
  "partitions": [
    {
      "device": "8:1",
      "id": "sda1",
      "partition": 1,
      "read_only": false,
      "size": 7863254528
    }
  ],
  "read_only": false,
  "removable": true,
  "rpm": 0,
  "serial": "08606E6B6612BE50D7168119",
  "size": 7864320000,
  "type": "usb",
  "usb_address": "2:7"
}

OVN ネットワークの ipv4.dhcp と ipv6.dhcp ¶

OVN ネットワークで IPv4 と IPv6 の DHCP をそれぞれ無効化できるようになりました。

これは、従来のマネージドブリッジと同様に、ipv4.dhcp と ipv6.dhcp の設定により行います。

物理ネットワーク上の ovn.ingress_mode ¶

OVN ネットワークに外部アドレスもしくはサブネットを割り当てる場合、特定の OVN ルーターがそのトラフィックを取り扱っていることを上流のゲートウェイに知らせる必要があります。

これまでは、L2 プロキシーを使って行っており、事実上 OVN は、処理を行わなければいけないネットワークとインスタンス上で、アップリンクネットワーク上の ARP/NDP パケットに対して応答することになっています。

これは多くのケースでうまく機能し、外部でルートを設定する必要はなくなります。しかし、OVN 自体で個別のアドレスレコードが必要となり、特に大きなサブネットではスケールしません（IPv4 での /24 や IPv6 での /64 を考えてみてください）。

このようなケースのために、新たに ovn.ingress_mode という設定が追加され、routed と設定できるようになりました。これは上流のルーターが、どのサブネットがどの OVN ルーターにルーティングされるのかを知っているため、OVN が各単独のアドレスごとに個別に処理する必要がないことを示しています。

これを https://github.com/stgraber/lxd-bgp のようなものと組み合わせて、上流のルーターのダイナミックなルーティング・プロトコルを使って、関連する OVN ルーターに対する必要なルートを自動的に設定できます。

物理ネットワーク上の ipv4.routes.anycast と ipv6.routes.anycast ¶

前のエントリーに関連して、LXD がルーティングされたサブネットに対して実行するチェックをバイパスするために、2つの新しい設定が追加されました。

この設定だけで、ふたつのネットワークのバックで使われたり、同時にふたつのインスタンスに割り当てられたりするのを防ぎます。しかし、外部ルーティングとダイナミックルーティングをサポートすることで、anycast を行うことができるようになります。

これがサポートされている環境では、ipv4.routes.anycast と ipv6.routes.anycast を true に設定し、サブネットの重複チェックを回避し、ふたつのインスタンスが同じパブリックアドレスを保持できるようにし、トラフィックの取得の決定を上流ルーターに任せることができます。

limits.instances プロジェクトオプション ¶

プロジェクトに設定できた limits.containers と limits.virtual-machines という制限に加えて、新たな制限が設定できるようになりました。 limits.instances を使って、プロジェクト内でタイプに関係なくインスタンス数を全体的に制限できます。

これに従って、次のように設定できます:

• limits.instances: 5
• limits.containers: 5
• limits.virtual-machines: 2

これにより、設定したプロジェクトでは 5 インスタンスまで持つことができます。そのすべてをコンテナにできますが、仮想マシンにできるのは 2 つだけとなります。

イメージとバックアップの zstd 圧縮 ¶

イメージとバックアップで zstd が使えるようになりました。

これは images.compression_algorithmとbackups.compression_algorithmで設定するか、lxc publish や lxc export で直接 --compression を使って指定できます。

LXD 4.8 リリースのお知らせ¶

12th of November 2020

はじめに ¶

LXD チームは LXD 4.8 のリリースをお知らせできることにとてもワクワクしています!

このリリースでは vTPM と VirtioFS のサポートが追加されました。そして cgroup2 サポートの作業が終了し、いくつか有用な機能の追加と改良を行いました。

また、ネットワークとストレージのトラッキングとライフサイクルが大幅に改良され、競合状態のクラス全体と通常のバグ修正の山が完全に排除されました。

Enjoy!

新機能とハイライト ¶

vTPM のサポート ¶

新しい tpm デバイスタイプが追加されました。コンテナと仮想マシンの両方でサポートされます。これは永続的な swtpm インスタンスを使い、通常は /dev/tpmX デバイスをインスタンス内で公開します。

stgraber@castiana:~$ lxc config device add tpm1 tpm tpm path=/dev/tpm0
Device tpm added to tpm1
stgraber@castiana:~$ lxc config device add tpm2 tpm tpm path=/dev/tpm0
Device tpm added to tpm2
stgraber@castiana:~$ lxc start tpm1 tpm2

stgraber@castiana:~$ lxc list tpm
+------+---------+------------------------+-------------------------------------------------+-----------------+-----------+
| NAME |  STATE  |          IPV4          |                      IPV6                       |      TYPE       | SNAPSHOTS |

stgraber@castiana:~$ lxc exec tpm1 -- tpm2_gettestresult
status:   success
stgraber@castiana:~$ lxc exec tpm2 -- tpm2_gettestresult
status:   success

仮想マシンに対する VirtioFS ¶

これまで、LXD はエージェントが構成するデバイスと disk デバイスを使って仮想マシンに対して公開される追加パスの両方のトランスポートとして 9p を使ってきました。

信頼性が高く、一般的に十分サポートされていますが、9p は高速ではありません。 virtiofs がこのための高速なオプションです。LXD エージェントがインスタンス内部で使用できる方を使用し、LXD は 9p と virtiofs の両方を通してアタッチしたデバイスを公開しています。

stgraber@castiana:~$ lxc init images:ubuntu/20.04/cloud vm1 --vm
Creating vm1
stgraber@castiana:~$ lxc config device add vm1 home disk source=/home/stgraber path=/mnt/virtiofs
Device home added to vm1
stgraber@castiana:~$ lxc start vm1
stgraber@castiana:~$ lxc exec vm1 bash
root@vm1:~# mkdir /mnt/9p
root@vm1:~# mount -t 9p lxd_home /mnt/9p/
root@vm1:~# dd if=/dev/zero of=/mnt/9p/test.img bs=4M count=100 conv=fdatasync
100+0 records in
100+0 records out
419430400 bytes (419 MB, 400 MiB) copied, 5.19642 s, 80.7 MB/s
root@vm1:~# dd if=/dev/zero of=/mnt/virtiofs/test.img bs=4M count=100 conv=fdatasync

100+0 records out
419430400 bytes (419 MB, 400 MiB) copied, 0.831076 s, 505 MB/s
root@vm1:~#

cgroup2 のフルサポート ¶

LXD はかなり長い間、ハイブリッドとフル cgroup2 システム上で機能してきました。しかし、その環境で実行された場合、必ずしもすべての制限が適用されていたわけではありませんでした。実際、ほとんどのコントローラーが起動時に制限された状態、またはサポートされないとして報告されていました。

次のものをのぞいて、LXD でサポートされるすべての制限に cgroup2 サポートを追加することで、これを大幅に改善しました。

• スワップの優先度指定とスワップの無効化（swappinessコントロールが必要）
• ネットワークの優先度（net_prioコントローラーが必要）

これら2つは現在、最新の Linux カーネルで相当する機能が cgroup2 にないためです。同等のソリューションが実装された際には、必ずその機能を使います。

デイリーのテストに cgroup1, スワップのアカウンティング付きのcgroup1、cgroup2 のテストを追加し、すべての制限が期待通り動作していることを https://jenkins.linuxcontainers.org/job/lxd-test-cgroup/ で確認しました。

zfs.clone_copy の rebase モード ¶

ZFS ストレージプールに追加された新しいオプションは、ソースのインスタンスが作成された元のイメージを追跡し、新しいインスタンスのオリジンとしてそれを使うように LXD に指示します。

これは、ソースインスタンスがイメージとともに持っているディスク上の差分を効率的に複製するので、そのコピーの結果としてディスク使用量が増えることを意味します。しかし、新しいインスタンスがソースと結びつくことも防ぎます。これにより、LXD が削除されたコピーのために削除されたデータセットを保持する必要がなくなり、ソースインスタンスを削除し、そのディスク領域を再利用できるようになります。

stgraber@castiana:~$ lxc launch images:ubuntu/20.04/cloud u1
Creating u1
Starting u1
stgraber@castiana:~$ sudo zfs list -t all -o name,origin castiana/lxd/containers/u1
NAME                        ORIGIN
castiana/lxd/containers/u1  castiana/lxd/images/0d8a2b851ecb4a2dfc6313cb8bae203f15c5ca51c3c80bc65b573224e7f59f59@readonly

stgraber@castiana:~$ lxc copy u1 u2
stgraber@castiana:~$ sudo zfs list -t all -o name,origin castiana/lxd/containers/u2
NAME                        ORIGIN
castiana/lxd/containers/u2  castiana/lxd/containers/u1@copy-e51ca348-32b5-4101-ac05-c656bf7c2a1e

stgraber@castiana:~$ lxc storage set default zfs.clone_copy false
stgraber@castiana:~$ lxc copy u1 u3
stgraber@castiana:~$ sudo zfs list -t all -o name,origin castiana/lxd/containers/u3
NAME                        ORIGIN
castiana/lxd/containers/u3  -

stgraber@castiana:~$ lxc storage set default zfs.clone_copy rebase
stgraber@castiana:~$ lxc copy u1 u4
stgraber@castiana:~$ sudo zfs list -t all -o name,origin castiana/lxd/containers/u4
NAME                        ORIGIN
castiana/lxd/containers/u4  castiana/lxd/images/0d8a2b851ecb4a2dfc6313cb8bae203f15c5ca51c3c80bc65b573224e7f59f59@readonly

この例では:

• u1 はイメージからコピーして作られた通常のコンテナです
• u2 はソースのスナップショットから作られた通常のコピーです
• u3 はスタンドアロンコピーで、u1 のデータ全体とイメージを複製します
• u4 はリベースコピーで、u1 の差分とイメージを複製します

lxc snapshot と lxc storage volume snapshot コマンドの --reuse オプション¶

lxc snapshot と lxc storage volume snapshot コマンドで、同じ名前で新しいスナップショットを作成する前に既存のスナップショットを削除できるようになりました。

stgraber@castiana:~$ lxc snapshot u1 foo
stgraber@castiana:~$ lxc snapshot u1 foo
Error: Add snapshot info to the database: This instance_snapshot already exists
stgraber@castiana:~$ lxc snapshot u1 foo --reuse
stgraber@castiana:~$

restarted ライフサイクルイベント ¶

LXD は重要な状態の変更を容易に追跡できるように lifecycle イベントをログに記録します。 これまで、インスタンスが再起動されたり内部から再起動されると、ログには stopped イベントとそれに続く started イベントが記録されていました。

これが、何が起こったかを正確に記述する単一の restarted イベントに置き換えられました。

stgraber@castiana:~$ lxc monitor --type=lifecycle
location: none
metadata:
  action: virtual-machine-restarted
  source: /1.0/virtual-machines/u2
timestamp: "2020-11-12T17:47:50.559795164-05:00"
type: lifecycle

ユーザからのリクエストのロギングの改良 ¶

LXD はすべての API 呼び出しの要求元をログメッセージと内部コンテキストデータに記録しています。しかし、これには少し制限がありました。どのプロトコル（unix, candid, tls）が使われたのかをログに記録しない、unix ソケット経由のリクエストの場合はユーザー名をログに記録できると言ったようなことのためです。

この問題は修正され、基本的な要求は次のように記録を行うようになりました:

• DBUG[11-12|18:26:10] Handling method=GET url=/1.0 ip=@ protocol=unix username=stgraber
• DBUG[11-12|23:26:59] Handling method=GET url=/1.0 ip=[2001:470:b0f8:1000:223:a4ff:fe01:16f]:48334 protocol=candid username=stgraber@stgraber.net
• DBUG[11-12|18:28:23] Handling method=GET url=/1.0 ip=127.0.0.1:47508 protocol=tls username=390fdd27ed5dc2408edc11fe602eafceb6c025ddbad9341dfdcb1056a8dd98b1

新機能とハイライト ¶

カスタムストレージボリュームのバックアップ（export/import） ¶

新たにカスタムボリュームに対する backup API が追加されました。これにより、cli で lxc storage volume export と lxc storage volume import が使えるようになりました。

stgraber@castiana:~$ lxc storage volume create default foo
Storage volume foo created
stgraber@castiana:~$ lxc storage volume export default foo
Backup exported successfully!
stgraber@castiana:~$ lxc storage volume delete default foo
Storage volume foo deleted
stgraber@castiana:~$ lxc storage volume import default backup.tar.gz
stgraber@castiana:~$ lxc storage volume list default

+----------------------------+------------------------------------------------------------------+-------------+--------------+---------+

別の名前でのインスタンスのインポート ¶

ついに別の名前でインスタンスのバックアップをインポートできるようになりました!

stgraber@castiana:~$ lxc init images:alpine/edge a1
Creating a1
stgraber@castiana:~$ lxc export a1
Backup exported successfully!
stgraber@castiana:~$ lxc import backup.tar.gz a2
stgraber@castiana:~$ lxc list a
+------+---------+------+------+-----------+-----------+

| a2   | STOPPED |      |      | CONTAINER | 0         |
+------+---------+------+------+-----------+-----------+

仮想マシンのメモリの圧縮（と再増加） ¶

仮想マシン内のバルーンデバイスを制御できるようになりました。メモリ容量を縮小させ、その後で再度前の制限にまで戻すことができるようになりました（さらなるメモリの追加にはリブートが必要です）。

stgraber@castiana:~$ lxc config show ubuntu-desktop | grep memory
  limits.memory: 2GiB
stgraber@castiana:~$ lxc exec ubuntu-desktop -- free -m
              total        used        free      shared  buff/cache   available
Mem:           1983         437         822           7         722        1386
Swap:           448           0         448
stgraber@castiana:~$ lxc config set ubuntu-desktop limits.memory 1500MiB
stgraber@castiana:~$ lxc exec ubuntu-desktop -- free -m
              total        used        free      shared  buff/cache   available
Mem:           1435         436         276           7         722         840
Swap:           448           0         448
stgraber@castiana:~$ lxc config set ubuntu-desktop limits.memory 2GiB
stgraber@castiana:~$ lxc exec ubuntu-desktop -- free -m
              total        used        free      shared  buff/cache   available
Mem:           1983         437         822           7         722        1387
Swap:           448           0         448
stgraber@castiana:~$

仮想マシンに対する USB デバイスのパススルー ¶

usb デバイスタイプが仮想マシンで使えるようになりました。 新しいデバイスを追加するには再起動が必要な点をのぞいては、コンテナと全く同じように動作します。

さらに、3 つの仮想ポートが LXD の VM に接続されており、lxc console --type=vga を使って、リモートの USB デバイスへのリダイレクションが使えます。

マイグレーション時の rsync 圧縮が設定可能に ¶

新たに真偽値の rsync.compression オプションがストレージプールに対して追加されました。

これにより、ネットワークが充分に高速でボトルネックにならず、圧縮が原因で CPU 使用率が問題となるような場合に、マイグレーション操作中の rsync 圧縮を無効にできるようになりました。

プロジェクトのネットワークで使えるアップリンクの制限 ¶

OVN ネットワーク機能を有効にしたプロジェクトを使っている場合、仮想マシンが使うアップリンクネットワークを制限できるようになりました。

アップリンクネットワークがひとつだけの場合、ユーザーが指定しなくても LXD は自動的にそのネットワークを使います。

これはプロジェクトに新たに追加された restricted.networks.uplinks オプションで行います。

新たに追加された管理 physical ネットワークタイプ ¶

新たに physical ネットワークタイプが追加されました。これは、現時点では OVN ネットワークに対するアップリンクとしてのみ使えます。設定には OVN ネットワークで使える IP アドレスのセットと、ゲートウェイ、DNS サーバが含まれています。

stgraber@castiana:~$ lxc network create external parent=eth0 ipv4.gateway=172.17.0.1/24 ipv4.ovn.ranges=172.17.0.100-172.17.0.150 dns.nameservers=1.1.1.1 --type=physical

+----------+----------+---------+----------------+---------------------------+-------------+---------+

OVN ネットワークでの外部ルーティングアドレス・サブネットのサポート ¶

新たな設定キー ipv4.routes.external と ipv6.routes.external を使って、外部の IP アドレスとサブネットを OVN ネットワーク上で実行中のインスタンスにルーティングできるようになりました。

プロジェクト設定の新たな restricted.networks.subnets キーと一緒に使用して、まずは外部の IPv4/IPv6 サブネットのセットを特定のプロジェクトに委任し、そのプロジェクト内でそれらのアドレスをインスタンスにルーティングできます。

LXD 4.6 リリースのお知らせ¶

18th of September 2020

はじめに ¶

LXD チームは LXD 4.6 のリリースをお知らせできることにとてもワクワクしています!

このリリースは短い開発サイクルでしたが、それでもかなり忙しいリリースでした。

このリリースのハイライトは、LXD プロジェクト内にネットワークを置くことができるようになったことに間違いありません。これで共有 LXD 環境内に自前のネットワークが作成できるようになりました。

Enjoy!

新機能とハイライト ¶

プロジェクト内のネットワーク ¶

OVN ネットワークに関するこれまでの作業をもとに、プロジェクト内に新たに features.networks が設定できるようになりました。これによりプロジェクトは OVN ベースで、他のプロジェクトから見えない自身のネットワークを持てるようになりました。

stgraber@castiana:~$ lxc network list
+---------+------+---------+-----------------+---------------------------+-------------------------------------+---------+---------+
|  NAME   | TYPE | MANAGED |      IPV4       |           IPV6            |             DESCRIPTION             | USED BY |  STATE  |
+---------+------+---------+-----------------+---------------------------+-------------------------------------+---------+---------+
| default | ovn  | YES     | 10.187.181.1/24 | fd42:bb2b:e7d1:f3ba::1/64 | Default OVN network for the project | 3       | CREATED |
+---------+------+---------+-----------------+---------------------------+-------------------------------------+---------+---------+

この機能を有効にすると、ホストインタフェースと OVN 以外のネットワークは見えなくなり、プロジェクトが直接所有するネットワークだけが残ります。

qemu 用の AppArmor プロファイル ¶

過去のリリースでの色々なサブプロセスに対する AppArmor プロファイルの生成に加えて、このリリースでは LXD 仮想マシンで使う qemu の制約が設定されるようになりました。

このリリースで raw.apparmor を仮想マシンに導入します。これは raw.qemu と同時に使われるときのみ有効です。通常の LXD 設定オプションは LXD が生成したプロファイルによって処理されます（そうでなければバグです）。

Dqlite の変更 ¶

LXD 4.5 をリリースした直後に、dqlite に大きな変更が加えられました。

ファイルシステムへの書き込みをインターセプトして、他のノードへのレプリケーションを行うためのフックを追加した sqlite3 のフォークに頼るのでなく、標準の sqlite3 から VFS アクセスを取得するこれまでとは異なるアプローチを使用するようになりました。

これはユーザーからは見えませんが、カスタムの sqlite3 と libco というふたつの依存関係を削除することで、パッケージを作成する際の助けになるでしょう。

dqlite を使う LXD は、標準の sqlite3 3.25 以上を使えるようになりました。

最後に、リモートストレージの改良と新しい AppArmor プロファイルに対する改良による、セキュリティとクラスタリングに対する素晴らしい改良が行われました。

Enjoy!

新機能とハイライト ¶

OVN 仮想ネットワークの初期サポート ¶

LXD 4.5 には OVN 仮想ネットワークのサポートが含まれます。

これは通常の LXD が管理するネットワークとして定義でき、これまでのブリッジと非常に似ています。しかし、クラスターノードをまたぐことができますし、サブネットが重複したり競合したりできます。

これは OVN を使って実現されています。そして、次の LXD リリースでは LXD プロジェクト内部のネットワークの基礎となります。LXD の OVN ネットワークは、親となる管理されたネットワークが必要です。現状では管理されたブリッジのみがサポートされます（SR-IOV と macvlan は 4.6 で対応予定）。

現時点では、ホスト上で OVN と Open vSwitch がセットアップされていれば、LXD で仮想ネットワークを作成できますし、通常のブリッジに対する方法と同じようにインスタンスに接続できます。

（4.5 の snap を使った Ubuntu 20.04 LTS での実行例です）

bpf システムコールインターセプションの初期実装 ¶

bpf システムコールに対するシステムコールインターセプションを有効化できるようになりました。これはコンテナの security.syscalls.intercept.bpf を使ってコントロールできます。

この機能を有効にした場合、特定のタイプの bpf プログラムを有効にしなければなりません。現時点では、security.syscalls.intercept.bpf.devices のみをサポートします。この機能は、device cgroup に紐付けられたプログラムをコンテナ内から読み込めるようにしています。

警告: 実際のプログラムで行われるバリデーションは、ホストからの明確な DoS を避けるための単純なサイズチェックのみです。この機能を有効にしたコンテナでは、かなり複雑な bpf プログラムをロードできます。そしてコンテナのスコープ外の情報を取得する可能性があります。信用できないコンテナに対しては許可するべきではありません。

ネイティブなターミナルデバイスの割り当てのサポート ¶

これまで、lxc exec のような操作のためのデバイス割り当てはホストシステムの devpts を通して行われていました。これは、コンテナのファイルシステムにアクセスしたり、ユーザーがコンテナ内の /dev/pts を何か悪意のあるものでマスクしたりすることを防ぐためのセキュリティの手段として行われていました。しかし、このアプローチには問題があります。コンテナ内部で見える制御デバイスは（外部に属するため）解決できないからです。

カーネルと LXC の作業で、コンテナ起動時に最初にマウントされる devpts インスタンスを安全に追跡できるようになりました。そして、コンテナ内の現在のマウントテーブルとやりとりすることなく、デバイスを割り当てできるようになりました。

これによる目に見える効果には次のようなものがあります。stdin/stdout/stderr 上で何かをリダイレクトする時に AppArmor ポリシーが混乱しにくくなったり、他の様々なソフトウェアが is-a-tty タイプのチェックを行うようなことがより通常の方法で動作するようになったりしました。

VGA コンソールが Windows 上で動くようになりました ¶

Windows ユーザーは、virt-viewer を　Chocolatey 経由かマニュアルでインストールできるようになりました。インストールすると、仮想マシンで lxc console --type=VGA を実行した場合に自動的にそれを検出し、使います。

リモートのストレージプールの扱いの改良 ¶

これまで、リモートのストレージプールにあるカスタムボリュームの処理方法は、クラスターメンバーごとにひとつのレコードを持つことで行われていました。これは、特にスナップショットを考慮すると、多数の重複するデータが生じていました。

スナップショットについては、ボリュームの重複のために、自動化されたスナップショットが各クラスターメンバーごとに発生し、意図したよりも多くのスナップショットと全体的な負荷につながっていました。

新たなデータベースの設計でこれはすべて解決しました。この設計では、シングルボリュームのエントリーが保持され、クラスター化されているとマークされます。したがって、特定のクラスターメンバーに結び付けられることはなくなりましたし、スケジュールされたスナップショットは、安定したハッシュメカニズムを使ってクラスター全体に分散するようになり、現在オンラインのクラスターメンバーがそれをどのように処理するかを決定します。

forkdns と forkproxy が AppArmor の制限のもとで実行されるようになりました ¶

LXD 4.4 での dnsmasq の制限に続き、LXD 4.5 では forkdns も制限するようになりました。このプロセスは、LXD クラスター上で Fan ベースのネットワークが実行されているときに使います。その名前のとおり、forkdns はすべてのクラスターメンバーに対するクエリを効果的に複製することで DNS 処理を行います。この制限により、重要なデータへのアクセスによる攻撃の可能性を防ぐことができます。

同様に、NAT ではない proxy デバイスで使われる forkproxy も、自身の AppArmor プロファイルを持っています。これは、アクセスする前提であるソケットと、プロキシーを行うのに必要なカーネルインフラストラクチャーの部分のみに制限をします。

lxc move でクラスターのターゲットを指定できるようになりました ¶

クラスター外部からクラスターにインスタンスを移動する際、--target を与えることで、インスタンスをホストするクラスターメンバーを指定できるようになりました。

LXD 2.0.12 リリースのお知らせ ¶

14th of August 2020

はじめに ¶

LXD チームが LXD 2.0.12 のリリースをお知らせします!

このリリースは、2021 年 6 月までサポートされる LXD 2.0 に対する 12 個目のバグフィックスリリースです。

バグ修正と改良点 ¶

一番古い LTS リリースである LXD 2.0 は 2017 年 10 月以来リリースがありませんでした。

この 2.0 系の LTS ブランチはセキュリティフィックスのみが行われるモードに入っています。このリリースは 2.0.11 に入らなかった古いバグ修正のいくつかと、LXD のこのブランチをビルドできるようにするための修正のみを含んでいます。

この一部として、LXD の依存関係のいくつかが、古いバージョンの Go でビルドできなくなり、LXD 2.0.11 が Go 1.13, 1.14, 1.15 で実行でき、少なくとも 1.11 ではビルドできないことを確認しました。

重要な修正やセキュリティ上の修正はないため、古い Go のバージョンを必要とするディストリビューションは 2.0.11 を維持するべきです。

最後に、LXD 2.0 LTS をまだ使っているユーザーは、このブランチでは重要なセキュリティ上の問題のみが修正され、1 年以内にサポートが終了しますので、より新しいバージョンにアップグレードすることをおすすめします。2.0 LTS から直接 4.0 LTS へアップグレードすることがサポートされています。

LXD 4.0.3 リリースのお知らせ¶

12th of August 2020

Introduction¶

LXD チームが LXD 4.0.3 のリリースをお知らせします!

このリリースは、2025 年 6 月までサポートされる LXD 4.0 に対する 3 つめのバグフィックスリリースです。

バグ修正と改良 ¶

このリリースには、開発ブランチからの数カ月分のバグフィックスと細かな改善が含まれています。

このリリースでは、VGA コンソール（LXD API 内の SPICE）とプロジェクトのディスク制限が含まれており、少し拡張された「マイナーな改良」となっています。4.0 リリースの主要な機能のいくつかのギャップを埋めるには、これが重要で（そして簡単だ）と思ったのです。

これらの機能は、データベーススキーマの更新を必要とせず、ダウングレードを防止したり、ディスク上の構造を変更したりすることもありませんので、変更を行うことは安全で重要であると感じました。

主な変更点は次のとおりです:

• lxc launch に新たに --console フラグが追加されました
• 仮想マシン内の /dev/lxd API のサポート
• /1.0/resources API 内で GPU 媒介（mediated）デバイスのサポート
• 仮想マシンに対する VGA コンソールのサポートの追加。クライアントで --console=vga（lxc launchもしくはlxc start）や --type=vga（lxc console）を指定します

LXD 4.4 リリースのお知らせ¶

31st of July 2020

はじめに ¶

LXD チームは LXD 4.4 のリリースをお知らせできることにワクワクしています!

このリリースは、ユーザーの方々すべてに新しい機能を提供する非常に忙しいリリースのひとつになりました。クラスタリングとマルチユーザーのデプロイメントを大幅に改良し、今後さらにエキサイティングな機能を追加するための基盤になっています。

Enjoy!

新機能とハイライト ¶

仮想マシン向けの VGA コンソール ¶

LXD 4.3 では、QEMU の設定に、デフォルトの virtio-gpu デバイスと SPICE 通信チャンネルのサポートを追加しました。

このリリースでは、実際に仮想 GPU にアタッチして操作するための通信メカニズムとクライアントロジックが追加されました。

lxc launch もしくは lxc start に --console=vga を指定するか、lxc console に --type=vga を指定できます。これを使うには、クライアントシステム上で remote-viewer か spicy が利用できる必要があります。もしどちらもない場合は、SPICE ソケットがクライアント上にマッピングされ、パスが提供されます。

この API は LXD 自身の websocket コンソール API に基づいていますが、spice-html5 と互換性があるため、LXD にアクセスする Web インターフェースに使用できます。

クラスタリングの failure domain ¶

LXD はクラスターメンバーに対する failure domain のコンセプトを公開するようになりました。

これにより、どのシステムが同時にオフラインになりそうかを LXD データベースに伝えることができますので、リーダーを選出する際や、クラスターメンバーを別のデータベースロールに昇格させたりするときに、より良い決定を下せるようになります。

failure domain の例としては、物理システムの電源回路、仮想マシン上で LXD が実行されている場合のホストシステム、クラウドインスタンス上で LXD が実行されている場合のクラウドアベイラビリティゾーンやリージョンがあります。

root@nuc01:~# lxc cluster list
+-------+----------------------------+----------+--------+-------------------+--------------+----------------+
| NAME  |            URL             | DATABASE | STATE  |      MESSAGE      | ARCHITECTURE | FAILURE DOMAIN |
+-------+----------------------------+----------+--------+-------------------+--------------+----------------+
| nuc01 | https://172.17.16.140:8443 | YES      | ONLINE | fully operational | x86_64       | pdu01          |

+-------+----------------------------+----------+--------+-------------------+--------------+----------------+

仮想マシンの /dev/lxd ¶

/dev/lxd API（英語サイト）が仮想マシンでも利用できるようになりました。

これはコンテナ内の場合と同じように動作します。しかし、イメージダウンロードの転送機能は利用できません。

デーモンの graceful シャットダウン ¶

これまでは、システムがシャットダウンされる際や LXD がアップデートされる際に、LXD がシャットダウンの指示を受けたときは、実行中のすべての操作が即座に中断されていました。

これはいくつかの不具合を引き起こしていました:

• いかなる lxc exec/console コマンドも即座に切断されていた
• イメージの更新が中断され、イメージが壊れたり失われたりする可能性があった
• マイグレーション中のインスタンスが、移行元サーバー上で停止したままの状態になっている可能性があった

新しいロジックは次のように処理しようとします:

• キャンセルできる操作はクリーンにキャンセルする
• 新しい操作の開始を防ぐ
• シャットダウン中のいかなる API 操作も防ぐ
• （exec/console のような）キャンセルできない操作を最大で 5 分待機する

残念ながら、lxc exec や lxc console のユーザーに数分後に切断されることを通知する良い方法はありません。どんな出力でも、その操作を妨げる可能性があるからです。しかし、5 分間の猶予時間は多くの場合で充分であり、現在の動作に比べて大きな改善になると考えています。

管理ネットワークの macvlan タイプと sriov タイプ ¶

管理ネットワークに、すでにある bridged に加えて新たにふたつのネットワークタイプが加わりました。

これは、macvlan もしくは sriov を使った管理ネットワークを定義し、（管理されたネットワークしか使えない）制限されたプロジェクトで使用できるようにすることができるようになったということです。

このように定義すると、MAAS サブネット、MTU、VLAN を事前に定義することができ、インスタンスごとに定義を繰り返し行う必要がありません。

これは、今後実装される仮想ネットワーク（OVN 経由）の外部レイヤーの基盤となります。これによりプロジェクトユーザーは、許可された管理ネットワークを使った独自のネットワークを、ホストシステムとコンフリクトする危険性なく構築できます。

root@lantea:~# lxc network create my-macvlan parent=enp11s0 --type=macvlan
Network my-macvlan created
root@lantea:~# lxc network create my-sriov parent=enp7s0 vlan=1017 --type=sriov

プロジェクト内のディスク使用量制限 ¶

最近、プロジェクトに対する制限（limit）と制約（restriction）が設定できるようになり、信頼できないユーザーが LXD を安全に使えるようになりました。その後、プロジェクトに欠けていた機能として、プロジェクトがディスクスペースのないホストシステムを実行できていたことがあります。

これは、新たに追加された limits.disk 設定キーがプロジェクトで利用可能になり、プロジェクトに対してトータルのディスク使用量を制限できるようになったことで問題ではなくなりました。

これはすべてのプロジェクトのインスタンス、イメージ、カスタムストレージボリュームに対して適用されます。

dnsmasq に対する AppArmor 制限 ¶

AppArmor サポートが拡張され、インスタンスに対する保護だけでなく、LXD が操作する他のサービスも保護するようになりました。

最初のこのような外部サービスは dnsmasq です。ネットワークごとの AppArmor プロファイルで実行されるようになりました。

LXD が起動する、長時間実行しつづけるプロセスのすべてをカバーするように、forkdns、forkproxy、qemu についても同様のプロファイルを追加する予定です。

リソース API の GPU 媒介（mediated）デバイス ¶

LXD は GPU の媒介デバイスを検出するようになりました。

これは Intel と NVIDIA の一部のデバイスでサポートされています。そして複数のプロファイルから選択できる物理デバイス上に仮想デバイスを作成できます。作成したデバイスは、仮想マシンの VFIO として使用できます。

現時点では、LXD は媒介デバイスを検出して表示するだけで、まだ仮想マシンでそれらを使用できません。

LXD 4.3 リリースのお知らせ¶

1st of July 2020

はじめに ¶

LXD チームは LXD 4.3 のリリースをお知らせできることにワクワクしています!

このリリースは、特に仮想マシンの使用における多数の改良を行っています。また、クラスターユーザー向けのかなりの数のバグ修正と一般的なパフォーマンスの改良が含まれています。

Enjoy!

新機能とハイライト ¶

カスタムのブロックストレージボリューム ¶

これまで、カスタムストレージボリュームはすべてファイルシステムでした。それをサポートするストレージバックエンド上のディレクトリ・サブボリューム・データセット、または他のバックエンド上のフォーマットされたブロックのいずれかでした。

LXD が仮想マシンをサポートするようになりましたので、（以前から可能であった 9p を使った）従来のボリューム上のファイルシステムを仮想マシンにアタッチできるのと同様に、追加の RAW ディスクを仮想マシンにアタッチできるようにする必要性がでてきました。

これによりブロックのカスタムストレージボリュームが使えるようになりました。

VM: グラフィカルコンソールの初期作業 ¶

すべての LXD VM で virtio-gpu と virtio-input デバイスがすぐに使える状態になりました。同様にローカルの Unix ソケットに接続されている spice チャンネルも使える状態になっています。

現状、spicy のようなクライアントを使ってソケットに直接接続できます。しかし、すぐに　LXD で lxc console を使った websocket 経由でリモートアクセスできるようになるでしょう。

VM: PCIe レイアウトの見直し ¶

VM に公開している全 virtio デバイスが確実に PCIe バス上にあるようにし、スロットの数を節約するために可能な限りデバイスはファンクションにマージするようにしました。

また、ネットワークデバイスは常に同じスロットに表示され、ハードウェアベースのネーミングが有効なときは一定の名前が得られるようなロジックが導入されています。

VM: GPU パススルー ¶

gpu タイプのデバイスを VM にアタッチし、VFIO 経由で物理 GPU を与えることができるようになりました。ホストと GPU を共有できるコンテナとは違い、VM では共有できないことに注意してください。

lxc start と lxc restart での直接のコンソールアタッチ ¶

単一のインスタンスを扱う場合、lxc start と lxc restart で --console オプションを指定できるようになりました。これにより、コマンドラインからすぐにコンソールにアタッチできるようになり、インスタンスのブートシーケンスを見ることができるようになります。

リソース API での Isolated CPU の表示 ¶

新たに、/1.0/resources API の全 CPU スレッドに isolated フィールドが追加されました。もし特定のスレッドが isolated な CPU と設定されている場合、このフィールドが true に設定されます。

これは通常はカーネルのコマンドラインで isolcpus= を指定してシステムを起動した場合に起こります。

LXD 4.2 リリースのお知らせ¶

5th of June 2020

はじめに ¶

LXD チームは、LXD 4.2 のリリースをお知らせすることにとてもワクワクしています！

このリリースでは、完全に新しい機能の導入と、多数のバックグラウンドの安定性の向上と速度の改良を行っています。

このリリースでのネットワークの改良は、プロジェクトごとの仮想ネットワークを OVN を使って実装するという最終的なゴールへ向かって設定した作業の始まりを示しています。この一環として、既存の OVS の扱いをいくつか修正し、VLAN フィルタリングと設定レポートをいくつか LXD に追加しました。

データベースやクラスタリングロジックの改良、問題の修正、テストカバレッジの改良、パフォーマンスの改善にもかなりの努力が払われています。

最後の注目点はセキュリティです。我々がここ数ヶ月〜数年の間に行ってきたアップストリームのカーネルでの作業から利益が得られるようになっています。このような機能を使って競合状態を避けながら、全体的に LXD をスピードアップしています。

Enjoy!

新機能とハイライト ¶

ブリッジでの VLAN フィルタリング ¶

物理的なネットワークスイッチに精通している人は、ポートやボンディングにタグなしやタグ付きの VLAN を設定するのに慣れているでしょう。Linux のソフトウェアスイッチでも、タグなし VLAN のポートごとの選択や、タグ付き VLAN のリストを全く同じように扱えます。

今回のリリースで、LXD はネイティブな Linux のブリッジと OVS の両方をサポートするようになりました。

ブリッジされた nic での vlan と vlan.tagged 設定キーを通して実装されます。vlan プロパティはタグなし VLAN を制御します。一方で、vlan.tagged は通過させるカンマ区切りのタグ付き VLAN のリストです。

ネットワーク状態情報の拡張 ¶

/1.0/networks/NAME/state API エンドポイントが拡張され、ボンディングとブリッジ固有の詳細が表示できるようになりました。これにより、LXD ホストをリモートから調査するのが容易になりました。特にクラスターの場合に役に立ちます。

ボンディングの詳細は次のように見えます:

stgraber@castiana:~$ lxc query /1.0/networks/bond0/state | jq .bond
{
  "down_delay": 500,
  "lower_devices": [
    "dum0",
    "dum1"
  ],
  "mii_frequency": 100,
  "mii_state": "up",
  "mode": "balance-rr",
  "transmit_policy": "layer2",
  "up_delay": 100
}

ブリッジの詳細は次のように見えます:

stgraber@castiana:~$ lxc query /1.0/networks/lxdbr0/state | jq .bridge
{
  "forward_delay": 1500,
  "id": "8000.06099e00b912",
  "stp": false,
  "upper_devices": [
    "tap1053b4fd",
    "tapef45d46d",
    "veth1651f83f",
    "veth8eb3fb1a"
  ],
  "vlan_default": 1,
  "vlan_filtering": true
}

カスタムの検索ドメインのサポート ¶

新たにネットワークで domain.search 設定キーが設定でき、これを使ってインスタンスに広告する検索のためのドメインのリストをカンマ区切りで設定するために使えます。

ネットワークリストの新たな IPv4 と IPv6 カラム ¶

lxc network list のデフォルト出力で新たに IPv4 と IPv6 のサブネットを表示するようになりました。 ネットワークを識別するのがかなり簡単になりました。

stgraber@castiana:~$ lxc network list
+--------+----------+---------+----------------+---------------------------+-------------+---------+

コンテナで mips と riscv64 の VM で s390x のサポート ¶

色々な MIPS バリアントのサポートが追加され、LXD で MIPS システムをビルドして実行できるようになりました。

RISC-V 64bit のサポートも追加され、コンテナで動作することを確認しました。

ubuntu@riscv64:~$ lxc list -cns46ta
+------+---------+----------------------+-----------------------------------------------+-----------+--------------+
| NAME |  STATE  |         IPV4         |                     IPV6                      |   TYPE    | ARCHITECTURE |
+------+---------+----------------------+-----------------------------------------------+-----------+--------------+
| b1   | RUNNING | 10.108.12.160 (eth0) | fd42:5832:5781:1eaf:216:3eff:fedd:884d (eth0) | CONTAINER | riscv64      |
+------+---------+----------------------+-----------------------------------------------+-----------+--------------+

両方とも、事実上イメージが存在しないので、今の所は Busybox を使うしかありません。

VM 側では、s390x 仮想マシンのサポートを追加しました。

すべてのコンテナのサブプロセスで pidfd を使用 ¶

LXD はコンテナ由来の PID を受け取るサブプロセスを頻繁に生成します。 これは状況次第では競合状態になる可能性があります。プロセスが終了し、我々がそれを検知する前に PID がリサイクルされる可能性があり、偶然間違った相手とやりとりしてしまう可能性があります。

Linux カーネルの pidfd に関する @brauner 氏の作業はこれを修正することを目的としています。LXD と LXC は PID を渡すのではなく、可能な限りファイルディスクリプタを特定のプロセスに渡すようにしています。

LVM ボリュームは必要なときのみアクティブに ¶

LVM はインスタンスが実行されていない限り、LV を非アクティブに保つことにより、ZFS や CEPH と同じように動作します。これにより /dev が乱雑さが減少し、小さなパフォーマンスの向上につながる可能性があります。

DB クエリのトレースサポート ¶

LXD のデータベースクエリをデバッグするために、新たに trace オプションが追加されました。 デーモンを --debug --trace database オプション付きで起動すると、すべての SQL クエリがログに記録されます。

より良いクラスターライフサイクルの扱い ¶

最近、外部の dqlite/raft/libco プロジェクトに対する自動テストを拡張し、他のダウンストリームユーザーが発見した多数の問題を修正し、LXD のロジックの一部をアップストリームのコードベースに移動しました。

LXD のクラスタリングテストは、リーダーシップの変更、ノードの再起動、デグレードのセットアップのより多くのケースをテストするために拡張されました。

クラスター化された環境でよくある問題の原因は時間のズレ（Time skew）です。数秒以上ずれると、スケジュールされたタスクやイベントなどで大混乱が引き起こされる可能性があります。これを解決するために、LXD は時間のズレを検出する方法として内部的なハートビートを使います。そして検出されたり解決された場合にログに警告を出力するようになりました。

データベース関数のクリーンアップ ¶

データベースの面では、データベースロジックのより多くがコードジェネレーターに移動され、コードを書く際にミスをするリスクを制限しています。その結果、多数の関数が非推奨となり、コードパスの一部が単一のトランザクション内で実行されるように最適化されました。

LXD 4.1 リリースのお知らせ¶

8th of May 2020

はじめに ¶

LXD チームは、LXD 4.1 のリリースをお知らせすることにとてもワクワクしています！

このリリースは 4.0 LTS リリースに続く初めてのフィーチャーリリースです。 通常のフィーチャーリリースですので、LXD 4.1 は、通常は約 1 ヶ月後にリリースされる 4.2 リリースまでのみサポートされます。

変更の大部分は、4.0 リリース以来行ってきたバグフィックスとリファクタリングです。しかし、多数の小さい機能の追加や改良が多数あります。

Enjoy!

新機能とハイライト ¶

イメージのプッシュとリレーのサポート ¶

インスタンスのコピー・移動と同様に、ソースサーバーが直接ターゲットサーバーにイメージをプッシュしたり、クライアントツールがサーバー間を中継したりできるようになりました。

これにより、サーバー間に存在するファイアウォールに対応するのが容易になります。

lxc image copy source:some-image target: --mode=push
lxc image copy source:some-image target: --mode=relay

routed NIC デバイスのルーティングテーブルサポート ¶

routed NIC デバイスに新たにオプションがふたつ追加されました:

• ipv4.host_table
• ipv6.host_table

このオプションは、どのルーティングテーブルにルーティングルールを挿入するかをコントロールします。 デフォルトでは、これはメインのルーティングテーブルですが、これを有効にすることで代替のルーティングテーブルを使いたいというユーザーがいました。

ipvlan NIC デバイスの L2 モード ¶

LXD の ipvlan デバイスはデフォルトでは Layer 3 シンメトリックモード（l3s）です。しかし、新たな mode オプションが導入され、Layer 2 モード（l2）も使えるようになりました。

リソース API の調整 ¶

新たに system セクションが追加され、多数の DMI フィールドと LXD を実行するのに使っているシステムのタイプ（物理、仮想、コンテナ）が表示されるようになりました。

加えて、NUMA ノードが CPU スレッドレベルでトラッキングされるようになり、CPU ダイの情報もコアレベルで記録されるようになりました。

次は CPU 出力の例です:

サーバー情報への OS データの追加 ¶

OS 情報が /1.0 と lxc info で出力されるようになりました:

stgraber@castiana:~$ lxc info | grep os_
  os_name: Ubuntu
  os_version: "20.04"

新たな lxd cluster remove-raft-node コマンド ¶

この新たに追加されたコマンドは、LXD がデータベースのクオラムの不足で起動できない場合に、強制的にデータベースメンバーを削除するのに使えます。

コマンドラインツールの表のソートの改良 ¶

リストは自然な順序でソートされるようになり、番号付きのアイテムが適切にソートされるようになりました。 加えて、ボリュームのリストでは、スナップショットが親のすぐ後に表示されるようになりました。

LXD 4.0 LTS リリースのお知らせ¶

31st of March 2020

はじめに ¶

LXD チームは、LXD 4.0 LTS のリリースをお知らせすることにとてもワクワクしています!

これは LXD の 3 つめの LTS リリースです。とても忙しく、そしてエキサイティングです! あとの ChangeLog は、LXD 3.23 ユーザーと 3.0 ユーザーの両方が私たちが準備したものを見れるように分けています。

私たちの他の LTS リリースと同様に、このリリースも 5 年間（2025 年 6 月まで）サポートされます。その間に多数のバグフィックスとセキュリティのポイントリリースが行われます。

LXD 3.0 に関しては、残り 3 年間のセキュリティ fix のみのメンテナンスモードに入る前の近いうちに、最後のバグフィックスリリースを 3.0.5 としてリリースしたいと思っています。

Enjoy!

互換性のない変更 ¶

--container-only の削除と、--instance-only への置き換え ¶

このリリースでの CLI の互換性のない変更は --container-only を --instance-only に置き換えるものだけです。フィーチャーリリースでは数ヶ月の間は両方をサポートします。4.0 リリースでは、非推奨の機能は削除されます。

3.23 ユーザー向けのハイライト ¶

virtual machines: バックアップサポート（import/export）¶

lxc export と lxc import が仮想マシンで使えるようになりました。

しかし、注意点があります。仮想マシンはコンテナとは異なり、大きなブロックデバイスとしてしかアクセスできません。これは、VM 内で実際にどれだけの容量が使われていたとしても、数 GB のデーターを読み込み圧縮する必要があるということです。

つまりエクスポートもインポートも長い時間がかかる可能性があるということです。

ZFS のようなバックエンドで --optimized オプションを使うと、同じタイプのストレージプールにインポートするなら、エクスポートの時間を大幅に短縮できるでしょう。

resources: リソース API の PCI、USB デバイス ¶

リソース API（/1.0/resources）が拡張され、システム上の PCI、USB デバイスが表示されるようになりました。これは特に、仮想マシンで VFIO パススルーや、コンテナで USB デバイスを扱う場合に有用です。

network: 複数の ipvlan NIC デバイスのサポート ¶

複数の ipvlan デバイスの ipv4.gateway と ipv6.gateway の両方もしくは片方が none に設定されている場合、複数の ipvlan デバイスを同じコンテナに追加できるようになりました。

network: routed NIC のホスト側アドレス設定のサポート ¶

routed NIC のホスト側のアドレスは ipv4.host_address と ipv6.host_address プロパティで設定できるようになりました。

clustering: クラスターロール編集のサポート ¶

新たに lxc cluster edit コマンドでクラスターのロールを編集できるようになりました。

現時点では書き込みできるロールがないので意味がないのですが、近いうちにいくつかロールを追加し、API とコマンドで管理できるようになるにする予定です。

instances: カスタムボリュームのディスク使用量 ¶

カスタムボリュームをアタッチしているコンテナが、state API （と lxc info）経由でボリュームの使用量をレポートするようになりました。

instances: スナップショットのディスク使用量 ¶

API でスナップショットごとのそれぞれのサイズを取得できるようになりました。

stgraber@castiana:~$ lxc snapshot c1
stgraber@castiana:~$ lxc query /1.0/instances/c1/snapshots/snap0 | jq .size
61440

これは再設計が済むとすぐに lxc info で表示されるようになるでしょう。

auth: パスワード不要の PKI モードのサポート ¶

管理された PKI を使って LXD を使う場合、その CA が署名したクライアント証明書であれば自動的に信頼するように LXD を設定できるようになりました。

これは core.trust_ca_certificates で設定します。

revoke を扱うため、server.ca と同時に設定する server.crl を CRL として受け入れます。

3.0 ユーザー向けのハイライト ¶

上記の機能と変更点に加えて、LXD 3.0 ブランチのユーザーは、以下の「新しい」機能が期待できるでしょう:

仮想マシン ¶

LXD はコンテナと仮想マシンの両方を実行できるようになりました。

デバイスや設定オプションによっては仮想マシンではまだ設定できないものがありますが、使い方や設定方法は同じように動作します。

操作によっては仮想マシン内で動作するエージェントが実行します（lxc exec と lxc file）。プロジェクトで作成したイメージのほとんどはエージェントがあらかじめインストールされています。

コンテナではなく仮想マシンを作成するのであれば、シンプルに lxc launch に --vm オプションを指定します。

VM イメージは主要なよく使われる Linux ディストリビューションのものが準備されており、将来的にも更に追加する予定です。

LXD 3.23 リリースのお知らせ¶

20th of March 2020

はじめに ¶

LXD チームは、LXD 3.23 のリリースをお知らせすることにとてもワクワクしています!

このリリースは最後の 3.x シリーズのリリースです。来週リリース予定の LXD 4.0 に少しの変更（いくつかの後方互換性のない CLI の調整）を加えています。

このリリースは、カスタムストレージボリューム、プロジェクト、仮想マシンを使うユーザーに特に機能が詰まったリリースです。

Enjoy!

ハイライト ¶

プロジェクトのカスタムストレージボリューム ¶

features.storage-volumes という新しいプロジェクトの機能が、すべての新しいプロジェクトで使えるようになりました。プロジェクトにカスタムボリュームを関連付けることができます。

この機能により、コンフリクトのリスクなしで専用のカスタムストレージボリュームのセットが作成できます。Canonical RBAC と組み合わせて、異なるプロジェクト間でストレージを適切に分離できるようになりました。

stgraber@castiana:~$ lxc storage volume list default | grep custom
+--------+----------+-------------+---------+
|  TYPE  |   NAME   | DESCRIPTION | USED BY |
+--------+----------+-------------+---------+
| custom | backups  |             | 1       |
+--------+----------+-------------+---------+
| custom | blah     |             | 0       |
+--------+----------+-------------+---------+
| custom | images   |             | 1       |
+--------+----------+-------------+---------+

stgraber@castiana:~$ lxc project create blah
Project blah created
stgraber@castiana:~$ lxc project switch blah

stgraber@castiana:~$ lxc storage volume create default foo
Storage volume foo created
stgraber@castiana:~$ lxc storage volume list default | grep custom
+--------+------+-------------+---------+
|  TYPE  | NAME | DESCRIPTION | USED BY |
+--------+------+-------------+---------+
| custom | foo  |             | 0       |
+--------+------+-------------+---------+
stgraber@castiana:~$

カスタムストレージボリュームのスナップショットのスケジューリング ¶

インスタンスと同じように、snapshots.schedule と snapshots.pattern 設定がカスタムボリュームでも使えるようになりました。

これらは lxc storage volume set POOL VOL KEY VALUE を使って直接設定できます。

カスタムストレージボリュームの有効期限 ¶

カスタムストレージボリュームで自動スナップショットが使えるようになったので、同時に有効期限の設定を行うのが良いでしょう。インスタンスで使えるものと合わせて、snapshots.expiry を使って設定できます。

既存のスナップショットの有効期限の編集は lxc storage volume edit POOL VOL/SNAP コマンドを使って行えます。

プロジェクトに対する制限値 ¶

プロジェクトごとに制限値をいくつか加えることができるようになりました。 現時点で使える制限値は次のものです:

• limits.containers 作成できるコンテナの総数
• limits.virtual-machines 作成できる仮想マシンの総数
• limits.cpu 使用できる仮想 CPU の数
• limits.memory 与えられるメモリーの総量
• limits.processes 起動できるプロセスの総数

最後の 3 つの設定は、プロジェクト内の全インスタンスで一致する設定を持つ必要があります。制限は実際の使用量ではなく、インスタンスに設定する制限値のトータルに対して適用されます。

プロジェクトに対する制約 ¶

（制限値に）加えて、いくつかの機能に対する制約もプロジェクトに適用できるようになりました。

オプションの全リストは https://linuxcontainers.org/lxd/docs/master/projects でご覧いただけます。

この機能は、restricted=true を使って制約をプロジェクトに適用すると、信頼できないユーザーに対して安全となるようにデフォルト設定されるようにデザインされています。その後制約を、潜在的により危険だったり、より制限の少ない設定やデバイスを許可するように緩めることができます。

Canonical RBAC とこの機能を組み合わせて、あまり信用できないユーザーに対してホスト上の完全な特権を与える必要なしに、共有 LXD サーバーやクラスターを実行できます。

バックアップ・エクスポートロジックの改良 ¶

lxc export が使うバックアップ・エクスポートロジックが更新されました。エクスポート中のディスクスペース量が減少しました。コンテナファイルは、ディスク上に作成される中間コピーファイルなしに直接圧縮した tarball に書き込まれます。

これによりエクスポートで使うディスクの使用量を大幅に減らすだけでなく、処理のスピードも向上しました。

VM: マイグレーションのサポート ¶

仮想マシンをローカルストレージプール間やリモートの LXD サーバー間でコピーできるようになりました。

この機能は "cold" マイグレーションのみであることに注意してください。仮想マシンは移動の間は停止していなければなりません。ライブマイグレーションは今後実装が予定されています。

VM: publish のサポート ¶

仮想マシンが lxc publish できるようになりました。より多くの仮想マシンを起動したり、他のサーバーに転送するのに使えるイメージが作成できます。

この機能はコンテナと完全に同じように動作しますが、仮想マシンのディスクはコンテナよりかなり大きいという事実を強調しておく必要があります。publish プロセス中にイメージを qcow2 に再度パックする必要がありますので、大きな仮想マシンを扱うためには、システム上にかなりの量のディスクの空き容量が必要になります。

LXD 3.22 リリースのお知らせ¶

6th of March 2020

はじめに ¶

LXD チームは、LXD 3.22 のリリースをお知らせすることにとてもワクワクしています!

このリリースでは、コンテナと仮想マシン両方にかなりの数の改良が加えられています。nftables サポートを追加し、xtables から切り替えられた一部の新しい Linux ディストリビューションに対する互換性が大きく向上しています。

このリリースとは別に、かなりの新しい VM イメージをイメージサーバーに追加しました。Ubuntu、Debian、Fedora、CentOS、OpenSUSE、ArchLinux の VM イメージを見つけられるでしょう。

Enjoy!

ハイライト ¶

プロジェクトに対するリソース制限 ¶

プロジェクトのリソース量を制限するのに使える新しい設定項目を追加しました:

• limits.containers
• limits.virtual-machines
• limits.cpu
• limits.memory
• limits.processes

CPU、メモリ、プロセスの制限を使う際に適用される制限がいくつかあります。詳しくは公式ドキュメントをご覧ください: プロジェクトの制限

ファイアウォールの nftables バックエンド ¶

最近の LXD リリースで、ファイアウォールのリクエストに対する内部抽象化レイヤーが導入されました。 これは、LXD ネットワークのファイアウォール、NAT、コンテナに対するプロキシーデバイス、IP や MAC フィルタリングなど、あらゆるものに対応しています。

このリリースの LXD で、新しいバックエンドとして、nft が既存の xtables 実装に加わりました。 起動時に LXD はシステムでどちらが現在使用されているかを検出し、以降はそれを使い続けます。

既存のバックエンドは lxc info で次のように参照できます:

stgraber@castiana:~$ lxc info | grep firewall:
  firewall: nftables

コンテナ: 非特権コンテナの Hugepages ¶

非特権コンテナで hugepages にアクセスできるようになりました。

• hugetlbfs ファイルシステムのマウントインターセプション
• hugepages に対して新たに制限を適用可能

x86_64 の設定例は次のようになります:

• security.syscalls.intercept.mount=true
• security.syscalls.intercept.mount.allowed=hugetlbfs
• limits.hugepages.1MB=1GB

hugepages の割り当ては、コンテナがすでに使っている通常のメモリに追加されることに注意してください。また、他の制限と同様に、制限を設定しないと無制限に hugepages を使えることに注意してください。

root@edfu:~# lxc init ubuntu:18.04 c1
Creating c1
root@edfu:~# lxc config set c1 security.syscalls.intercept.mount true
root@edfu:~# lxc config set c1 security.syscalls.intercept.mount.allowed hugetlbfs
root@edfu:~# lxc config set c1 limits.hugepages.2MB 1GB
root@edfu:~# lxc start c1

root@edfu:~# lxc exec c1 bash
root@c1:~# mkdir /dev/hugepages ; mount -t hugetlbfs hugetlbfs /dev/hugepages
root@c1:~# ls -lh /dev/hugepages/
total 0

VM: 9p ディスクデバイスのサポート ¶

LXD の仮想マシンに長く待望されていた機能のひとつが、ホストから仮想マシンに任意のパスを渡す機能でした。

LXD 3.22 で LXD 自身とエージェントのロジックを組み合わせることでこれを可能にしました。

これがプロファイルを通してコンテナと仮想マシンの両方で使えるようになりました。

root@edfu:~# lxc profile create shared-data
Profile shared-data created
root@edfu:~# lxc profile device add shared-data home disk source=/home path=/mnt/home
Device home added to shared-data
root@edfu:~# lxc profile device add shared-data srv disk source=/srv path=/mnt/srv
Device srv added to shared-data

root@edfu:~# lxc launch images:fedora/31 f31-ctn -p default -p shared-data
Creating f31-ctn
Starting f31-ctn
root@edfu:~# lxc launch images:fedora/31 f31-vm -p default -p shared-data --vm
Creating f31-vm
Starting f31-vm

root@edfu:~# lxc exec f31-ctn -- df -ah | grep /mnt
/dev/sdb1                   220G   12G  197G   6% /mnt/home
/dev/sdb1                   220G   12G  197G   6% /mnt/srv
root@edfu:~# lxc exec f31-vm -- df -ah | grep /mnt
lxd_home        220G   12G  197G   6% /mnt/home
lxd_srv         220G   12G  197G   6% /mnt/srv

VM: ファイルテンプレートのサポート ¶

イメージ内のテンプレートファイルが仮想マシンにも使えるようになりました。 テンプレートは、設定内で使用可能なメタデータを使ってホスト上の LXD が設定を読み込み、読み込まれたファイルは仮想マシンにインストールするためにエージェントに渡されます。

カスタムイメージへのテンプレートの追加がコンテナと同様に動作するようになり、LXD のイメージサーバー images: （https://images.linuxcontainers.org/）でも使われています。

LXD 3.21 リリースのお知らせ¶

13th of February 2020

はじめに ¶

LXD チームは、LXD 3.21 のリリースをお知らせすることにとてもワクワクしています!

このリリースは、これまでと同様の 2 週間の短い開発サイクルのリリースで、多数のストレージ、VM、ネットワークのバグフィックスとリファクタリングを含んでいます。

機能的には、ネットワークインターフェースを接続する新たな簡単な方法、新たなクラスタリングデータベースの設定、多数の仮想マシンの改良があります。

Enjoy!

ハイライト¶

LXD が管理するネットワークに対する新たな接続方法 ¶

LXD が直接管理しているブリッジインターフェースを使う場合（lxc network list 参照）、次のように直接そのブリッジにインスタンスを接続できるようになりました:

eth0:
    type: nic
    network: lxdbr0
    name: eth0

もしくは lxc config device add c1 eth0 nic network=lxdbr0 name=eth0 のように実行します。

nictype: bridged や parent: lxdbr0 というプロパティは設定する必要がありません。代わりに network に LXD ネットワークを設定すれば、すべて完了です。

このモードでは、ブリッジの MTU は自動的にネットワークインターフェースから継承します。IPv4/IPv6 アドレスは、ネットワークに設定されたサブネットに対して検証されます。そして、MAAS IPv4, IPv6 サブネットは、個別のインターフェースでなくネットワークを通して設定されるようになりました。

Ceph ドライバーの新しいストレージドライバーインフラストラクチャーへの移植 ¶

Ceph ストレージドライバーが、新しいストレージインフラストラクチャーに移植される最新で最後のドライバーです。ユーザーに見えない変更がありますが、LXD で Ceph をお使いのユーザーは、まずは重要ではないシステムで 3.21 へのアップグレードを試し、ストレージに関連する問題をすみやかに報告することをおすすめします。

この最後のドライバーの移植で、LXD のコードベースからすべての古いストレージインフラストラクチャーを削除する作業を始められるようになりました。これにより、今後の保守が大幅に容易になります。

クラスタリング: アクティブとスタンバイのメンバーの数を設定できるようになりました ¶

クラスターに対する設定オプションをふたつ追加しました。

• cluster.max_voters は、期待するアクティブデータベースクラスターのメンバー数を設定します（投票 (voting)）
• cluster.max_standby は、期待するスタンバイデータベースクラスターのメンバー数を設定します（非投票 (non-voting)）

デフォルトの設定は 3 台の投票 (voting) メンバーと、2 台のスタンバイメンバーです。投票 (voting) メンバーがダウンした場合、スタンバイは速やかに投票 (voting) に昇格し、予備の待機メンバーがスタンバイに昇格するかもしれません。

投票 (voting) メンバーの数を増やすとデータベースのパフォーマンスが低下するでしょう。これは、変更に同意するメンバーの数が増えるからです。スタンバイメンバーの数を増やしてもデータベースのパフォーマンスに影響は与えませんが、データベースバイナリストリームを取得する必要のあるメンバーが増えるので、ネットワーク負荷が増加するでしょう。

ほとんど間髪を入れずに 2, 3 のメンバーを失う可能性があるクラスターでのみ、これらのデフォルト値を増やすことを検討すべきです。

VM: CPU ピンニングとトポロジー ¶

limits.cpu で、コンテナでサポートされているように、特定の CPU ID を設定できるようになりました。例: limits.cpu: 0,2、limits.cpu: 0-3。

リストで指定された物理 CPU（やスレッド）への VM の仮想 CPU のピンニングに加えて、LXD は VM の CPU トポロジーを一致させようとします。

先の例の limits.cpu: 0,2 は、デュアルコアのハイパースレッドサポートの Intel システムでは、最初のコアとそのハイパースレッドを指します。その結果、仮想マシンではシングルソケット、シングルコア、ハイパースレッド CPU で構成され、物理ハードウェアと一致するように両方のスレッドが固定されます。

同じロジックが、ハイパースレッディングサポートの有無に関わらず、マルチソケット、マルチコアのシステムをサポートします。limits.cpu で指定された CPU が実際のハードウェア構成（各ソケットの同じ数のコア、すべてのコア上の同じ数のスレッド、…）と一致する限り、LXD は VM 設定を一致させ、ピンニングも一致するように設定することを保証します。

要求された設定が正しくない場合（ハードウェアと一致しない場合）、LXD はフォールバックし、シングルソケットのハイパースレッディングなしのマルチコア VM を提供し、設定した CPU ID それぞれをコアとして扱います。これは明らかに理想的な状況ではありませんので、このような状況になれば、警告が LXD ログに記録されます。

VM: ネットワークとストレージの最適化 ¶

ネットワークパフォーマンスを改良するため、LXD はネットワークデバイスに vhost_net を使います。

ストレージフロントでは、virtio-scsi ドライブで discard が有効になり、ブロックを破棄したり、ベースのファイルストレージを縮小したり、バックのドライブがブロックをより適切に管理できるようになったりしました。

VM: IPv6 アドレスのエージェントレスのレポーティング ¶

これまでは、仮想マシンの IP アドレスは LXD の DHCP サーバからのみ取得していました。 これは IPv4 では確実に動作しますが、ほとんどの IPv6 デプロイで使う SLAAC では、DHCPv6 リースが付属していないので、LXD では取得されません。

これを回避する方法のひとつは、VM 内で実行する LXD エージェントに頼ることでした。このエージェントは仮想マシン向けにネットワーク情報を取得するのに使います。

しかし、それが不可能な場合でも、LXD は一致する IPv6 アドレスの近傍レコードも参照するようになりました。

LXD 3.20 リリースのお知らせ¶

30th of January 2020

はじめに ¶

LXD チームは、LXD 3.20 のリリースをお知らせすることにとてもワクワクしています!

私たちは、LXD 3.19 のリリースのあとに行われた多数の機能強化とバグ修正をすばやくまとめるために、通常の 1 ヶ月ごとのリリースから 2 週間のリリースに短縮しました。LXD 4.0 のリリースまでこのペースを保つつもりで、その後通常の 1 ヶ月ごとのリリースに戻る予定です。

このリリースは、オースティンのテキサス大学の学生のコントリビュートによる、3 つの機能追加・改良を含みます。

• API コレクションのサーバ側でのサポート
• 新しい unix-hotplug デバイスタイプ
• バックグラウンドプロセス管理の見直し

これらのインテグレーションに加えて、私たちが考える VM ストーリーの現在存在するギャップを埋めることにもフォーカスを当てており、3.19 リリース以来の多数のバグを修正し、ネットワークインターフェースの処理を完了し、ppc64le サポートを追加し、ブートデバイスの順序設定をサポートしました。

Enjoy!

ハイライト ¶

API コレクションのサーバー側でのサポート ¶

ユーザーが扱うインスタンスやイメージがますます大きくなるにつれ、それらのすべてのレコードをクライアント側でフィルタリングすることは非常にコストが高くなる可能性があります。このリリースでは、サーバー側でのフィルタリングのインフラストラクチャと初期実装を追加しました。

これは次のようになります:

stgraber@castiana:~/data/code/lxc/lxd (lxc/master)$ lxc query '/1.0/instances?filter=config.image.os%20eq%20ubuntu'
[
    "/1.0/instances/snapcraft",
    "/1.0/instances/ups-monitor",
    "/1.0/instances/v1",
    "/1.0/instances/maas01",
    "/1.0/instances/steam",
    "/1.0/instances/lxd-build"
]

これは、URL エンコーディングを使って、フィルターとして config.image.os eq ubuntu を使っています。フィルタリングオプションの詳しくはこちら をご参照ください。

新しい unix-hotplug デバイスタイプ ¶

このデバイスタイプは usb と unix-char と unix-block のちょうど中間のようなものです。

特定の vendorid/productid を指定でき、その結果として unix-char/unix-block デバイスを自動的にコンテナに渡すことができます。

USB デバイスの例です:

stgraber@castiana:~$ lxc config device add c1 kingston unix-hotplug vendorid=0951 productid=1666
Device kingston added to c1

stgraber@castiana:~$ lxc exec c1 bash

スタンバイクラスターメンバーのサポート ¶

dqlite ベースのクラスターデータベースロジックが拡張され、新たに dqlite でサポートされた standby ロールと idle ロールが使えるようになりました。

この変更で、すべてのクラスターメンバーは dqlite に統合され、それぞれが次の 3 つのロールをひとつを持つようになりました:

• voting メンバー
• standby メンバー
• idle メンバー

設定は 3 つの voting メンバー、5 つの standby メンバーと、残りのメンバーが idle となります。voting メンバーが失われると、短いタイムアウトの後、voting メンバーでないメンバーが自動的に voting に昇格します。idle メンバーは voting と standby メンバーの必要数を維持するために、voting メンバー以外に昇格します。

その結果、はるかに回復力のある LXD クラスターになり、メンテナンスや電源障害のためにオフラインになるクラスターメンバーを適切に処理します。

VM: NIC サポートの拡張 ¶

このリリースで、仮想マシンの nic デバイスがサポートされました:

• macvlan (macvtapを使用)
• sriov
• physical
• p2p

SR-IOV と物理 NIC のパススルーは、仮想マシンへの PCI パススルーを使っています。これには適切な IOMMU セットアップと適切な PCI セットアップが必要です。

VM: ブートの優先度 ¶

仮想マシンで使う disk と nic タイプのデバイスすべてに boot.priority オプションが新たに存在するようになりました。優先度が高いほど、VM がそのデバイスからブートする可能性が高くなります。

root ディスクからブートするデフォルトの動作でなく、常にネットワークから VM をブートしたい場合に特に役に立ちます。

VM: ppc64le ホストのサポート ¶

ppc64le ホストの初期サポートを追加しました。これは、PCIe でなく通常の PCI バスが使われ、ファームウェアが UEFI でなく SLOF であるという点を除いて、x86_64 と aarch64 とほぼ同じように動作します。

LXD 3.19 リリースのお知らせ¶

16th of January 2020

はじめに ¶

LXD チームは、LXD 3.19 のリリースをお知らせすることにとてもワクワクしています!

このリリースは、私たちがここ数ヶ月取り組んできた大きな機能である仮想マシンサポートを含む、盛りだくさんのリリースです! システム上で LXD を実行し、まったく同じ CLI や API を通して、そしてクラスターデプロイの一部としても、コンテナと仮想マシンの両方を管理できるようになりました!

このリリースでは、多数の他の機能、ユーザ体験の改良、修正を行っており、今までで最も精力的なリリースになっています。

Enjoy!

PS: このリリースは、通常の月ごとの開発サイクルより少し長い時間がかかりました。この遅れはストレージレイヤーの再実装の大部分を完成させただけでなく、それをベースに仮想マシンサポートを行いたいと思ったからです。次の数回の LXD リリースは、3/4 月の大物リリースである 4.0 を前にペースを早めて行う予定です。

ハイライト ¶

仮想マシンサポート ¶

このリリースのメインのハイライトは LXD を使って仮想マシンを実行するための初期サポートであることは間違いありません。

まさしくその通りです。システムコンテナと仮想マシンを組み合わせられるようになりました。 仮想マシンもイメージから作成され、コンテナと同じストレージプールに格納され、コンテナと同じネットワークに接続され、プロファイルを通して同じ設定を共有できます。

仮想マシン内部で LXD エージェントを実行すると、通常の exec、file、info 機能が使えるので、仮想マシンの操作がコンテナの操作とほとんど同じに行えます。

これは初期の作業であり、まだ実装されていない部分が多数ありませすが、現状、仮想マシンが Ubuntu イメージ（今後は他のディストリビューションでも）から、もしくは PXE ブートから作成できます。

すべての仮想マシンはセキュアブート有効の UEFI を実行し、コア数とメモリ割り当て、メモリに専用の Hugepage を使うかどうかの設定をサポートします。 cloud-init は設定されたドライブを通して、もしくはイメージ内に存在するエージェントを使うことで VM で使用できます。

Ubuntu 18.04 VM の作成し、エージェントをインストールし、詳細を問い合わせ、内部でシェルを取得する基本的な例を示します:

ストレージレイヤーの再実装 ¶

仮想マシンサポートの作業の一環として、ストレージレイヤーを完全に書き直しました。 これにより、仮想マシン向けのブロックデバイスの保存サポートを追加し、長年に渡って蓄積してきた多くの問題を解決し、ストレージレイヤーの進化のために行われました。

これにはユーザーに見える影響はありません。適切に動作すれば、新しいロジックは以前のロジックと全く同じように動作するはずですが、バグがある可能性はあります。

以降は、新しいストレージドライバーサポートの追加が容易になりました。そして、優れた抽象化が導入されたおかげで、ストレージ操作の大部分が共通のロジックを使うようになり、コードの重複とコードベース全体でのバグの重複リスクが大幅に減少しました。

これだけの膨大な作業であればバグがあることが予想されます。私たちは報告があった問題に可能な限り対処するために素早く対応するようにします。そして、安定する前に candidate チャンネルを通して、あまり重要でないシステム上で LXD 3.19 をテストすることを強くおすすめします。

テキサス大学の学生による貢献 ¶

オースティンのテキサス大学のたくさんの学生グループが、仮想化クラスの課題の一部として LXD 機能への貢献を行ってきています。

このリリースでは、次のものを含みます:

• 複数アーキテクチャのクラスタリング
• Ceph rbd/fs ボリュームのダイレクトアタッチ
• イメージへのプロファイルのアタッチ
• ディスクデバイスのカスタムなマウントオプション
• LVM ストライピング（ストレージレイヤーの再実装により一部の作業は置き換えられました）

現在、さらに多くの機能が行われ、次の LXD リリースに含まれる予定です。

LXD チームは、これらの貢献とプロジェクトへの新しいコントリビューターとのやりとりを本当に楽しんでおり、参加の学生の実りが多くなることを願っています。

その他の新機能 ¶

lxc list カラムのデバイスキー ¶

lxc list に、デバイスの設定値を表示する追加カラムの定義ができるようになりました。

例:

stgraber@castiana:~$ lxc list -c nst,config:image.os:OS,devices:eth0.parent:BRIDGE
+--------+---------+-----------------+--------+--------+
|  NAME  |  STATE  |      TYPE       |   OS   | BRIDGE |
+--------+---------+-----------------+--------+--------+
| maas01 | STOPPED | CONTAINER       | ubuntu | lxdbr0 |
+--------+---------+-----------------+--------+--------+
| v1     | STOPPED | VIRTUAL-MACHINE | ubuntu | lxdbr0 |
+--------+---------+-----------------+--------+--------+
| v2     | STOPPED | VIRTUAL-MACHINE | ubuntu | lxdbr0 |
+--------+---------+-----------------+--------+--------+
| v3     | STOPPED | VIRTUAL-MACHINE |        | lxdbr0 |
+--------+---------+-----------------+--------+--------+

routed ネットワークモード ¶

新たにネットワークインターフェースの nictype に routed モードを追加しました。 routedモードには下層の liblxc につい最近追加された機能が必要です。そして、このモードは実質的にコンテナとホスト間のポイント・ツー・ポイントのリンクを設定し、そのリンクを使って IP をコンテナへルーティングします。

stgraber@castiana:~$ lxc config device add c1 eth0 nic nictype=routed ipv4.address=10.255.243.155
Device eth0 added to c1
stgraber@castiana:~$ lxc start c1
stgraber@castiana:~$ lxc list c1
+------+---------+-----------------------+------+-----------+-----------+
| NAME |  STATE  |         IPV4          | IPV6 |   TYPE    | SNAPSHOTS |
+------+---------+-----------------------+------+-----------+-----------+
| c1   | RUNNING | 10.255.243.155 (eth0) |      | CONTAINER | 0         |
+------+---------+-----------------------+------+-----------+-----------+

コンテナへの Ceph RBD と FS のダイレクトアタッチ ¶

LXD が管理していない Ceph 上の既存の RBD もしくは FS ボリュームを持っており、従来のディスクデバイス経由でアタッチできないユーザーは、そのようなボリュームを直接コンテナにアタッチできるようになりました。

これは disk デバイスの source に特別な値を設定して行います。

例: - source=ceph-rbd:pool/volume - source=ceph-fs:fs/path

さらに、Ceph クラスターとユーザーを設定するために、設定項目が追加されました。

• ceph.cluster_name
• ceph.user_name

ディスクデバイスのカスタムマウントオプション ¶

新たに disk デバイスに対して raw.mount_options の設定が追加されました。 これは任意に設定可能なリストで、コンテナにディスクをアタッチする際に使うマウントオプションをカンマ区切りで指定します。

イメージへのプロファイルのアタッチ ¶

複数プロファイルのセット（組み合わせ）をプロファイルに設定できるようになりました。イメージから作られた新しいインスタンスは、デフォルトプロファイルの代わりにプロファイルのセットを使います。

これは lxc image edit 経由で設定し、イメージの自動更新でも維持されます。

stgraber@castiana:~$ lxc image show a722a8eb4d31
auto_update: true
properties:
  architecture: amd64
  description: Alpine 3.8 amd64 (20200116_13:00)

mount システムコールのインターセプト ¶

システムコールのインターセプトのためのレイヤーが拡張され、mount システムコールのインターセプトをサポートしました。

これは、通常は非特権コンテナ内でのマウントが制限されているファイルシステムをマウントできるようにするために使えます。しかし、もっと重要な事は、FUSE ドライバーへのマウント呼び出しの透過的なリダイレクションを可能にすることです。

新しい設定オプションは次の通りです:

• security.syscalls.intercept.mount (機能の有効・無効を設定 )
• security.syscalls.intercept.mount.allowed (マウントを許可するファイルシステムのリスト )
• security.syscalls.intercept.mount.fuse (FUSE へのリダイレクトをするファイルシステムリスト )
• security.syscalls.intercept.mount.shift (ShiftFS レイヤーの設定を自動的に行うかどうか )

完全に信頼していないコンテナに対して allowed パーミッションを決して与えないでください。この設定は、カーネルのスーパーブロックパーサーにコンテナを直接公開します。カーネルを攻撃したり、ホストをクラッシュさせたり、コンテナから脱出したりすることに使えます。

次の例は、ext4 を許可する例と、より安全な代替手段として FUSE を使う場合の例です:

リソース API の追加 ¶

リソース API のディスクエントリーに、新たにふたつのフィールドが追加されました。

• FirmwareVersion はネットワークカードのファームウェアリビジョンを公開します
• DeviceID は /dev/disk/by-id 以下での検索に適したデバイスの識別子を示します

NVME ドライブの例は次のようになります:

stgraber@castiana:~$ lxc query /1.0/resources | jq .storage.disks[0]
{
  "block_size": 512,
  "device": "259:0",
  "device_id": "nvme-eui.0000000001000000e4d25cafae2e4c00",
  "device_path": "pci-0000:05:00.0-nvme-1",
  "firmware_version": "PSF121C",
  "id": "nvme0n1",
  "model": "INTEL SSDPEKKW256G7",
  "numa_node": 0,
  "partitions": [
    {
      "device": "259:1",
      "id": "nvme0n1p1",
      "partition": 1,
      "read_only": false,
      "size": 52428800
    },
    {
      "device": "259:2",

  "wwn": "eui.0000000001000000e4d25cafae2e4c00"
}

マルチアーキテクチャークラスタリング ¶

クラスターメンバーに異なるアーキテクチャのメンバーを混在させることができるようになりました。 LXD はイメージのアーキテクチャーに基づいた正しいシステム上にコンテナを配置します。

極端な例として、3 つの異なる Intel 以外のアーキテクチャーで作られるクラスタを示します:

root@cluster:~# lxc cluster list
+---------------+----------------------------+----------+--------+-------------------+--------------+
|     NAME      |            URL             | DATABASE | STATE  |      MESSAGE      | ARCHITECTURE |

クラスターセットアップロジックの改良 ¶

このリリース以降、LXD クラスターを構築する場合、クラスターの一部である最初の 3 つのサーバーはデータベースノードとして機能し、データベースの完全なコピーを受信し、データベーストランザクションの投票を始めます。

この動作により、2 サーバーからなるクラスターがデータベースメンバーの数が偶数であっても安全に動作し、適切なクオラムを防ぎ、どちらかのサーバーがオフラインになっても全データーベースが効率的に停止すると考えられるようになりました。

新しい動作では、3 つめのサーバーが加わるまでは単一のデータベースで動作し続け、3 つめのサーバーが参加した時点で、3 つのサーバすべてがデータベースサーバーとなります。

LXD 3.20 ではスタンバイデータベースノードの導入で、クラスター自身をオフラインにすることなしに複数のデータベースノードをオフラインにできるようになり、この点がさらに改善されます。

未管理ブリッジの MAC フィルタリング ¶

security.mac_filtering が、LXD が管理していないネットワークブリッジに接続された nic デバイスで使えるようになりました。

設定可能な Ceph データプール名 ¶

データとメタデータ用に別々の OSD プールが必要な場合、データを保存する場所をコントロールできる ceph.osd.data_pool_name が新たに追加されました。メタデータは ceph.osd.pool_name で参照するプールに保存されます。

LVM ストライピングサポート ¶

LVM ストライピングがサポートされるようになりました。volume.lvm.stripes と volume.lvm.stripes.size で設定できます。

cgroup2 リソース制限の初期サポート ¶

新しい cgroup 抽象レイヤーが LXD に追加され、v2 リソースコントローラーの初期マッピングも追加されました。これに最近の liblxc の改良を組み合わせて、ほとんどのリソース制限が cgroup v2 環境で機能するようになりました。

作成時のバックアップ圧縮の設定 ¶

backups.compression_algorithm を設定することで、バックアップで使う圧縮アルゴリズムが設定できます。これはすべての新しいバックアップに適用されるグローバルな設定です。

インスタンスの publish コマンド（lxc publish）で、バックアップの作成時に圧縮アルゴリズムを上書きできるようになりました。これは lxc export --compression-algorithm で公開されます。

squashfs を使った圧縮されたバックアップとイメージのサポート ¶

圧縮アルゴリズムとして、イメージとバックアップの両方で squashfs を選択できるようになりました。 これ以前は、LXD は squashfs で圧縮されたイメージを使うことはできましたが、LXD 自身で squashfs イメージを作成できませんでした。
