That's an interesting idea. If you have an extra video card, you can 'passthrough' that card to the guest, enable paravirt DMA access and access that video card in the guest. In case you cannot use paravirt DMA (eg., Windows guests), you can use 1-1 mapping of the guest OS in the host address space. I sent out patches for passthrough for PCI devices and PV DMA for 64-bit hosts and guests last week. For 1-1 mapping of guests in host address space, there are some patches that were sent out to the lkml, but there are some issues to be ironed out first, but it might work for you. If you take this up seriously, I'd urge you to create a page on the wiki so that interested people will be able to follow the development and help with testing.
