    You are not right. I have played games inside a XEN vm at the same speed as with windows. 3D-Mark Ventage shows only 6000 instead of 6100 points. The loss is on CPU side.

    Regarding Xen VGA passthrough...

    Would anybody mind commenting on this...

    http://phoronix.com/forums/showthrea...e-way-to-go!!!

    How is it that such a thing is already possible on Linux but hardly anybody uses it?

    In the video shown on the Xen website, the VM is started in console mode. Doing this while X is running wouldn't be really easy ie. switching from the virtual graphic adapter in windowed mode to the VGA passthrough in fullscreen. It would imply saving all the X stack state before giving up the control to the VM, then repost the video hardware when coming back. Not quite grand public.

    You could then install say a native nvidia or ATI Windows driver for your video card in your Windows guests and should get very close to native performance as you are sharing the physical video device with the host. That would be sweet for running Windows within your Linux host for those Windows games you can't do without...without leaving Linux

    That could be quite possible once the technology matures.

    Also, if you really care about games on Linux, please stop hoping for patchwork stuff like this in order to play Windows games. As stated before: a Windows sale does not help Linux in any shape or form. Go buy the indie stuff that does support Linux instead like the humble indie bundle, Overgrowth and Enemy Territory: Quake Wars.

    EDIT:
    Felt the urge to plug Overgrowth
    until linux gets more commercial products, you can't honestly expect the average home desktop (or office) user to strictly use linux 100% for all of their needs. i have a separate computer i use strictly for gaming and nothing else, which runs windows. if linux could natively run everything i own and have yet-to-own, i wouldn't need windows at all. but if virtualbox can virtualize windows with vga passthrough, then that would still leave linux as the main os.

    btw, who said i paid for windows?

    the PCI pass-through support sounds potentially awesome, but i have questions:

    1. what does this mean to me as the owner of an IOMMU supporting system (890FX chipset) as a desktop user?

    2. does this mean that VB is finally supporting IOMMU#?

    cheers
