Re: [Qemu-devel] QEMU Video Driver for Win NT-based systems

[Grzegorz Kulewski]

Another idea is to allow qemu use second graphic card in your pc (not used 
by the host). I have one spare GeForce 2 @ PCI so I will be glad to see 
this implemented. Before that we will probably need working PCI layer in 
qemu. And I we can track the area in graphic memory used by current screen 
maybe it is possible to write driver that will copy screen from second 
card to a window on first (this could be implemented on guest or on host).
