[Xen-devel] Re: graphics passthrough with VT-d

[Christian Tramnitz <chris.ace@xxxxxxx>]

It seems this was unrelated to the gfx_passthrough, I started with 
"fresh" domU configs and also reinstalled them and now its working WITH 
gfx_passthrough and USB (the whole controller as pci device) passthrough.
I do have (all as pass-through):
- accelerated video (even survives hardware detection during Win7 
installation)
- audio (onboard HDA, using digital output)
- USB (UHCI only, EHCI crashed Windows during HW detection)
running Windows 7 x64 (b7600).


I'll now try to swap the primary and secondary gfx (both ATI) to get 
some real 3D horse-power.


Best regards,
   Christian
