Xen VGA Passthrough: integrated GPU for dom0 and PCI card for win guest?

1

I know you need at least two graphics cards for VGA passthrough... but I'm worried the integrated graphics card will get disabled once I plug in the PCI card. could xen (xcp) override this default behavior?

I would like to use the integrated gpu (i5 3470) for dom0 and then use VGA passthrough for a PCI card (Nvidea gForce GT 430) for the HVM windows guest... using the motherboard H77M-itx

i wouldn't mind getting another pci graphics card but I was silly and went for the itx board that only has one pci slot.

I haven't tried yet but, I think I may have a chance.

http://superuser.com/questions/241157/how-can-i-enable-onboard-graphics-and-dedicated-card-simultaneously

they said 6 series and up chipsets support gpu and PCI at the same time. Now I noticed in my bios under advanced->North Bridge Configuration, there is an option to choose the preferred graphics card whether onboard or PCI.

I chose the onboard card as default.

When I setup the windows VM i'll see if the VGA passthrough works...

Check your BIOS settings for features related to onboard video and maybe dual screen support. My BIOS lets me control what the onboard video does when a video card is detected.
