+ ### はじめに <!-- Introduction -->
+ <!--
+ The LXD team is very excited to announce the release of LXD 4.2!
+ -->
+ 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！
+
+ <!--
+ This release brings quite a few new features and a lot of background stability and speed improvements.
+ -->
+ 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。
+
+ <!--
+ The networking improvements in this release mark the beginning of more work we've set for ourselves with the final goal of having per-project virtual networks implemented through OVN. As part of this, we've done some fixes in our existing OVS handling and added VLAN filtering and some useful config reporting to LXD.
+ -->
+ 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。
+
+ <!--
+ Quite a bit of effort is also going in improving our database and clustering logic, fixing issues, improving test coverage and improving performance.
+ -->
+ 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。
+
+ <!--
+ One last area of focus is security where we've now begun to reap the benefits from some upstream kernel work we've been doing for the past few months/years, using those features to avoid race conditions and speed up LXD in general.
+ -->
+ 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 <!-- New features and highlights -->
+ #### ブリッジでの VLAN フィルタリング <!-- VLAN filtering on bridges -->
+ <!--
+ Those familiar with physical network switches are no doubt used to configuring your untagged and tagged VLANs for your ports or bonds. Linux software switching allows for the exact same thing, per-port selection of your untagged VLAN and a list of tagged VLANs.
+ -->
+ 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。
+
+ <!--
+ Now LXD exposes that with support for both native Linux bridging and OVS.
+ -->
+ 現在、LXD はネイティブな Linux のブリッジと OVS の両方をサポートしています。
+
+ <!--
+ This is implemented through the `vlan` and `vlan.tagged` config keys on a bridged `nic` device. The `vlan` property controls the untagged VLAN while `vlan.tagged` is a comma separated list of tagged VLANs to let through.
+ -->
+ 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 <!-- Expanded network state information -->
+ <!--
+ The `/1.0/networks/NAME/state` API endpoint was expanded to show bond and bridge specific details. This makes it easier to remotely inspect a LXD host, particularly useful when in a cluster.
+ -->
+ `/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。
+
+ <!--
+ The bond details look like this:
+ -->
+ ボンディングの詳細は次のように見えます:
+
+ stgraber at 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
+ }
+
+ <!--
+ The bridge details look like this:
+ -->
+ ブリッジの詳細は次のように見えます:
+
+ stgraber at 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 <!-- Support for custom search domains -->
+ <!--
+ A new `domain.search` config key on networks can be used to set a comma-separate listed of search domains to advertise to the instances.
+ -->
+ 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 <!-- New IPv4 and IPv6 columns in network lists -->
+ <!--
+ The default output of `lxc network list` now shows the IPv4 and IPv6 subnets.
+ This makes it quite a bit easier to recognize your networks.
+ -->
+ `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 at castiana:~$ lxc network list

+ | wlan0 | physical | NO | | | | 0 |
+ +--------+----------+---------+----------------+---------------------------+-------------+---------+
+
+ #### コンテナで mips と riscv64 の、VM で s390x のサポート <!-- mips & riscv64 support for containers and s390x support for VMs -->
+ <!--
+ Support for various MIPS variants has been added, allowing LXD to be built and run on MIPS systems.
+ -->
+ 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 support was also added and confirmed to work with containers.
+ -->
+ 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 at 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 |
+ +------+---------+----------------------+-----------------------------------------------+-----------+--------------+
+
+ <!--
+ In both cases, image selection is effectively non-existent, so you're pretty much stuck with Busybox for now!
+ -->
+ 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。
+
+ <!--
+ On the VM front, we've added support for s390x virtual machines.
+ -->
+ 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 <!-- Using pidfds for all container subprocesses -->
+ <!--
+ LXD frequently spawns subprocesses that are fed a PID coming from a container.
+ This can be racy in some situations, allowing for the process to exit and the PID be recycled before we interact with it, causing us to accidentally interact with the wrong thing.
+ -->
+ 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際どい状況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。
+
+ <!--
+ That's what @brauner's work on pidfds in the Linux kernel is meant to fix and LXD and LXC now make us of those whenever possible, passing a file descriptor to a particular process rather than passing its PID.
+ -->
+ 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 volumes only active when needed -->
+ <!--
+ LVM now behaves in the same way as ZFS and CEPH by keeping LVs inactive unless the instance is running. This reduces clutter in /dev and can lead to some small performance improvements.
+ -->
+ 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 <!-- DB query tracing support -->
+ <!--
+ A new `trace` option has been added for debugging database queries in LXD.
+ Starting the daemon with `--debug --trace database` will have all SQL queries logged.
+ -->
+ 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 <!-- Better cluster life-cycle handling -->
+ <!--
+ We've recently been expanding our automated testing for our external dqlite/raft/libco projects, fixed a number of issues found by other downstream users and moved some of LXD's logic into the upstream codebases.
+ -->
+ 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's clustering tests have also been expanded to test more cases of leadership changes, node restarts and handling of degraded setups.
+ -->
+ 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。
+
+ <!--
+ A common source of issues with any clustered environment is time skew.
+ You get more than a few seconds and it can wreck havoc on scheduled tasks, events and more. To help with this, LXD now uses its internal heartbeats as a way to detect time skews and will log a warning in its log whenever one is detected or resolved.
+ -->
+ 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。数秒以上かかると、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 <!-- Cleaned up database functions -->
+ <!--
+ Still on the database front, a lot more of the database logic has been moved over to our code generator, limiting the risk of mistakes when writing that code. A number of functions have been deprecated as a result and some codepaths optimized to run within a single transation.
+ -->
+ 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変換内で実行されるように最適化されました。

A common source of issues with any clustered environment is time skew.
You get more than a few seconds and it can wreck havoc on scheduled tasks, events and more. To help with this, LXD now uses its internal heartbeats as a way to detect time skews and will log a warning in its log whenever one is detected or resolved.

#### データベース関数のクリーンアップ <!-- Cleaned up database functions -->
<!--
Still on the database front, a lot more of the database logic has been moved over to our code generator, limiting the risk of mistakes when writing that code. A number of functions have been deprecated as a result and some codepaths optimized to run within a single transation.
-->
- 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変換内で実行されるように最適化されました。
