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

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

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
