have you looked at the Spice ?
what i get from my quick google read on this was that QXL vGPU driver found in Spice offers higher fidelity than other traditional virtual video drivers
other reoccurring theme was something about that the virtual driver res can't be bigger than your host OS res or the host graphics card is going to like it
from what it sounds like Spice handles the resolution dynamically based on the host and guest support - but i'm no export on spice - something to look at if you haven't already
