> If you are not working with the graphic's card driver then what you describe > sounds feasible and may actually work. I don't quite follow what you mean by "if you are notworking with the graphics card driver", could you clarify it for me? My hope would be to use the normal Direct3D API to send work to the card through the normal stack including the card's driver; but I would specify an off-screen rendering target. Or alternatively, I would specify an on-screen rendering target but no monitor would actually attached to the card. Xen/Qemu would still present the normal Cirrus emulated graphics card to the Windows DomU (but there would be nothing to back it up so any writes to it would just be dropped?)
