Seems it's possible to use vga-passthrough with kvm-qemu in Linux.
Anyone have IOMMU mobo and tried this with Windows 9x?
Tried pci-passthrough with virtualbox but there seems no way to boot guest from attached GPU (using rage128 vr in pass through); it simply displays screen from xorg window while being stuck with virtualbox's GPU, and running Linux with rage128 causes guest screen to go blank and crash during boot (have rage128 drivers installed in guest btw). Seems XEN doesn't like Windows 9x; at least from what I've heard.
It's quite amazing IMO to see how successful folks have been with vgapassthrough with current GPUs. Being able to boot into your own custom Linux install, startup a Windows Vista-8 guest, and run games with native GPU speed and driver. That's just mind blowing. You can literally be compiling, encoding movies, and ripping CDs in the background at your own taste, while playing games simultaneously in a Windows guest, inside your favorite OS. Perhaps onchip gpu's won't be such a waste after all...?
