Many tricky things need to be done, such as > frame buffer, VGA guest bios, etc. So current VT-d in Xen doesn't > support assigning graphics card yet. I wonder if those complications (which I don't pretend to understand) would go away if the graphics card did not have to produce any output to a locally attached monitor? My goal is not to render the Windows DomU graphics to the local monitor, but rather to just use the graphics device to do work like rendering to an off-screen buffer. I can then do whatever I want with that buffer, such as send it over the network to another machine for display. The Windows DomU would be running completely headless...I can RDP into it to administer it. Would that make it more feasible?
