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.
