错误：virPidFileAcquirePath：422：无法获取 pid 文件'/run/user/1000/libvirt/libvirtd.pid'：资源暂时不可用

有人知道如何修复这个问题吗？计算机似乎告诉我 libvirt 没有可连接的虚拟机。我可能错了。

我开始使用 vitrd。我正在考虑使用以下命令连接到我在服务器上启动的虚拟机盒子在 CentOS7 上。

使用命令检查 libvirtd 是否在你的系统上运行

ps -ef | grep libvirtd

使用命令移动你的 pid 文件

mv /var/run/libvirtd.pid /var/run/libvirtd.pid.old

使用命令停止 libvirtd 服务

systemctl stop libvirtd.service

然后使用命令重新开始

systemctl start libvirtd.service
