This is called X11 forwarding.  The virt-manager is running on the
'server' and with the '-X' option you are able to see the GUI for
the remote 'server'.

There is no way how to configure it and there is actually no need to
configure it like that.  If you open virt-manager on your system (not
using X11 forwarding on the remote 'server') it will connect to the
libvirt over ssh connection.

The difference is that in the first case (X11 forwarding) you are
receiving GUI data (which is usually slow) and in the second case you
are receiving raw data from libvirt, spice, etc.
