在使用 virt-manager 时报错 Unable to connect to libvirt qemu:///- system

具体报错信息如下

Unable to connect to libvirt.   
Failed to connect socket to '/var/run/libvirt/libvirt-sock': Permission denied

Verify that:
 - The 'libvirt-bin' package is installed
 - The 'libvirtd' daemon has been started
 - You are member of the 'libvirtd' group

Libvirt URI is: qemu:///system

将文件 libvirt-sock 权限改为 666 即可

sudo chmod 666 /var/run/libvirt/libvirt-sock

重启 virt manager 即可。
