LXD 5.2 リリースのお知らせ

26th of May 2022

はじめに

LXD チームは LXD 5.2 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!

今回は移行やストレージに関する様々な問題の解決にフォーカスを当てているため、機能的にはそれほど多くのものがあるわけではありませんが、それでも歓迎すべき変更や改良がいくつか含まれています。

Enjoy!

新機能とハイライト

リソース API での VPD 情報

スマート NIC のような複雑な PCI デバイスの識別と追跡を簡単にするため、利用できる場合は LXD リソース API で PCI VPD（Vital Product Data）を公開するようになりました。

次はサーバーに内蔵されたネットワークカードのエントリーの例です:

{
        "driver": "ixgbe",
        "driver_version": "5.17.6+",
        "iommu_group": 54,      
        "numa_node": 0,
        "pci_address": "0000:01:00.1",
        "product": "Ethernet Controller 10-Gigabit X540-AT2",
        "product_id": "1528",   
        "vendor": "Intel Corporation",
        "vendor_id": "8086",    
        "vpd": {
                "entries": {
                        "PN": "AOC-UR-i4XT",
                        "SN": "OA14BS031362",
                        "V0": "0100",
                        "V1": "1.01",
                        "V2": "002590FB3BBD",
                        "V3": "002590FB3BBC",   
                        "V4": "",               
                        "V5": "",               
                        "VA": "2"               
                },
                "product_name": "Supermicro Network Adapter"
        }
}

プロジェクトをまたいだプロファイルのコピー

コマンドラインツールで、--target-project パラメーターを使ってあるプロジェクトから別のプロジェクトへのプロファイルのコピーができるようになりました。

stgraber@dakara:~$ lxc profile list --project default
+---------+---------------------+---------+
|  NAME   |     DESCRIPTION     | USED BY |
+---------+---------------------+---------+
| bar     |                     | 0       |
+---------+---------------------+---------+

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

/dev/lxd API での HTTP ストリーミングサポート

LXD インスタンス内の /dev/lxd/sock を通して公開される REST API は長らく /1.0/events エンドポイントを持ち、LXD から来るイベントをリスンしていました。

これまで、このエンドポイントでは websocket を使用する必要があり、安定した websocket サポートを持たない cloud-init やその他のツールでは問題となることがわかっていました。

このようなツールに対応するため、このエンドポイントは HTTP ストリーミングもサポートするようになり、HTTP エンドポイントを通して JSON 構造体のストリームを取得できるようになりました。

root@u1:~# curl --unix-socket /dev/lxd/sock -N lxd/1.0/events
{"type":"config","timestamp":"2022-05-26T23:33:03.481505039-04:00","metadata":{"key":"user.foo","old_value":"","value":"bar"}}

CLI でのサーバーサイドフィルタリングの使用

大きな lxc list の呼び出しでスピードが上がるのがわかる以外には、直接目に見える変化はありませんが、多数のフィルタリングがクライアントサイドのフィルタリングではなくサーバーサイドのフィルタリングを使うようになりました。

仮想マシンでの Ceph librbd

直接目につかない他の変更点に、Ceph 上に保存された仮想マシンの安定性と柔軟性をかなり向上させるものがあります。以前の LXD のリリースでは、LXD はカーネルの RBD ドライバーに依存し、VM のディスクをマッピングし、それを QEMU に公開していました。

このリリースから、LXD は直接 Ceph とやりとりするために QEMU に librbd の使用を指示するようになりました。カーネルドライバーを使わないようにするだけでなく、システムの ceph.conf を通して Ceph RBD キャッシュを調整できるようになりました。
