我的 xcp-ng 伺服器出現問題，我在 Linux xcp-ng 4.19.0+1 上使用 xcp 中心 20.04.01。在問題發生之前我沒有做任何更新之類的事情，幾個月來一切都正常工作。
這是我仍然可以做的：
- 透過xcp中心和SSH連接伺服器
- 查看所有伺服器和快照
- 啟動或停止虛擬機
但是，我面臨一些問題：
- “效能”標籤未顯示任何資料。
- 用於運行虛擬機器的控制台沒有顯示任何內容。
- 已啟動的虛擬機器不回應 IP。
- VM 選項卡呈灰色
我嘗試過了 ：
- 分析日誌並尋找錯誤，但沒有成功
- xe-toolstack-重新啟動
- 重新啟動虛擬機
- 重新啟動整個伺服器
誰能提供解決這些問題的步驟？
