Re: [Xen-devel] [PATCH] Pass-through a graphic card

["Jean Guyader" <jean.guyader@xxxxxxxxx>]

Neo,

There is no code that is graphic card dependent. It is graphic card
dependent because this patch re-execute the native vga bios inside the
guest.
I tried with ATI and when windows loads the ATI driver the guest reboots.
Good luck with your tests.
