Libvirt doesn't provide vnc console, it's only framework to manage running of 
kvm/xen/vbox processes, which can provide vnc access to virtual machine's console.
You should think of this virtual machine as of real machine than needs X server 
to run gui apps. Do you have X server running on your virtual machine? You do 
not need X server started on virtual machine if you are using ssh X forwarding 
because you are executing app process on virtual machine and forwarding its 
connection to X server to X server running on your host/remote machine. (Yes, 
this method is great because it allows to run gui aps on headless server).

BTW even if you will run X on you virtual machine you will have problems with 
copy/paste buffer which will not work through kvm vnc, so maybe you'll better 
with ssh -X.
