我删除了 Libvirt 用户，现在 virt-manager 抛出“无法连接到 libvirt qemu:///system。”

我知道这并不明智，只是想找到解决办法。

完整错误信息：

Unable to connect to libvirt qemu:///system.

Verify that the 'libvirtd' daemon is running.

Libvirt URI is: qemu:///system

您需要重新配置 LibVirt 包以运行安装后脚本：

  • 对于 Ubuntu 16.04 LTS 你需要运行：

    sudo dpkg-reconfigure libvirt-bin

  • 对于 Ubuntu 18.04 LTS，你需要运行：

    sudo dpkg-reconfigure libvirtd-daemon-system
