xcp-ng サーバーに問題があり、Linux xcp-ng 4.19.0+1 で xcp center 20.04.01 を使用しています。問題が発生する前に更新などの操作は何も行っていませんでしたが、数か月間すべて正常に動作していました。
私がまだできることは次のとおりです:
- xcp centerとSSH経由でサーバーに接続する
- すべてのサーバーとスナップショットを表示
- 仮想マシンを起動または停止する
しかし、次のようないくつかの問題に直面しています。
- 「パフォーマンス」タブにデータが表示されません。
- 実行中の VM のコンソールに何も表示されません。
- 起動された VM が IP に応答しません。
- VMタブがグレー表示
やってみました ：
- ログを分析してエラーを検索しても見つからない
- xe-toolstack の再起動
- VMを再起動する
- サーバー全体を再起動する
これらの問題を解決するための手順を教えてくれる人はいますか?
