There is no need to run a GUI on the host with or without direct guest SSH 
access. The virtual console for Xen & QEMU guests is made available via a
VNC server listening on host's 127.0.0.1 address. So you can access the 
virtual console from a remote host by tunnelling the appropriate VNC port 
over SSH to the host. You can find the appropriate port by running

   virsh --connect qemu:///session dumpxml <guestname>  | grep vnc

Dan.
