LXD 3.0.4 リリースのお知らせ¶

21st of June 2019

はじめに ¶

LXD チームは LXD 3.0.4 のリリースをお知らせできることをうれしく思います！

Stable に対するバグフィックスのリリースですので、大きな変更はありません。バグフィックスと細かな使い勝手の改良にフォーカスしています。

ハイライト ¶

マイグレーション機能のネゴシエーション ¶

マイグレーション時に rsync と ZFS のオプションをネゴシエートするようになりました。これにより異なる LXD やホスト OS のバージョン間での移動時に、コンテナマイグレーションの問題を防げるようになりました。

進捗報告が表示されるコマンドの追加 ¶

lxc launch や lxc publish などのいくつかのコマンドで、進捗情報が表示されるケースが増えました。
