and what about giving to Windows HVM the entire access to the graphic card.
It doesn't matter if my dom0 is headless, all I want it to do is to emulate the network card. I want dom0 to work as a firewall for domU.

I was guessing that RDP would have better performance than VNC, but I could be
wrong...  In any case, I guess running VNC within the guest may give better
display performance than running it in dom0.
