When installing KVM, in order to facilitate later installation of virtual machines, GNOME Desktop is installed directly, so that you can directly manage desktop operations. After installing KVM-related controls, start vncserver to report an error, as follows:

[root@localhost home] # systemctl status-l vncserver@:1.service
