Hello all,
    I have already use xen for about a year. I use recently released Opensuse 11.3 (use Xen 4.0) for my experiment. I want to run 3D test in HVM(windows xp), so I want to use VGA passthrough technology. But there is something not work properly.
    I google a lot of time, it says, I/O virtualisation should be enabled, but I can solve it.
    I run "xm dmesg" command, in the output, there is "(Xen) I/O virtualisation disabled", what I should do to enable I/O virtualisation.
    Can anyone help me?
    motherboard verison is intel DG965RY.
    Thank you!

Di Zhang
