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。
