I've been trying to make XEN vga passthrough work for five days now. I've installed Fedora 15, set-up Xen 4.0, but I can't seem to get any devices to be listed, when I run
xm pci-list-assignable-devices
I've tried many kernels. Could any of you share the way you made VGA passthrough work ?

I am running a i5 2400 on an h61 chipset motherboard.
