錯誤：virPidFileAcquirePath:422：無法獲取 pid 文件“/run/user/1000/libvirt/libvirtd.pid”：資源暫時不可用

任何人有任何想法如何解決這個問題？看起來電腦告訴我 libvirt 沒有要連接的 VM。我在那裡可能不合時宜。

我開始玩 vitrd。我正在考慮使用 CentOS7 上的機器連接到我在伺服器上啟動的虛擬機。

error : virPidFileAcquirePath:422 : Failed to acquire pid file '/run/user/1000/libvirt/libvirtd.pid': Resource temporarily unavailable
