Ubuntu 22.04サーバーでKVMブリッジを構成するためにnetplanとsystemd-networkdを使用しています。ブリッジは機能しますが、networkctlはステータスのデフォルトインターフェイスを表示しますconfiguring。とりわけ、systemd-networkd-wait-onlineブリッジインターフェイスを明示的に要求することでタイムアウトの問題を解決できますが、systemd-networkd-wait-onlineネットワーク設定がまだ「理想的」であるようには見えません。多くの方法を試しましたが、基本インターフェイスをconfigured状態に切り替えることはできません。
これは私のシステム設定です。
