解决方法

步骤一：配置libvirt

# 修改libvirtd配置
vi /etc/libvirt/libvirtd.conf
unix_sock_group = "libvirt"
unix_sock_ro_perms = "0770"
unix_sock_rw_perms = "0770"
unix_sock_admin_perms = "0700"
unix_sock_dir = "/var/run/libvirt"
auth_unix_ro = "polkit"
auth_unix_rw = "polkit"

步骤二： 添加用户组

#添加组
usermod -aG libvirt $(whoami)

步骤三： 重启libvirtd服务

systemctl restart libvirtd
