[Xen-devel] Re: Accellerated windows graphics drivers

[Andrés Lagar Cavilla <andreslc@xxxxxxxxxxxxxx>]

James, VMGL should hit the ground running for your UNIXes, but I haven't 
done any work towards Windows compatibility. You might find this more 
immediately useful

Your mileage will vary, and is only OpenGL, but looks promising. No easy 
solution for Direct 3D. dxgl and wined3d claim to translate Direct3D 
calls into OpenGL. They look scary. But you need something like this 
sooner rather than later, as dom0 is UNIX. And don't forget getting your 
GPU drivers to work in dom0... Andres On Wed, Mar 12, 2008 at 11:40:29AM

I think wine can already do this.. ie. convert d3d calls to GL calls. 

Maybe this is interesting too: http://www.cs.toronto.edu/~andreslc/xen-gl/
