Re: [Xen-devel] Xen PCI/VGA passthrough failing on Ubuntu 12.04 (64-bit)

I believe your biggest problem is that the A75 chipset does not support
IOMMU.  Based on what I've read, it would be impossible to do vga
passthrough without it.  You best bet is a 990FX or 970 motherboard with any
AM3 or AM3+ cpu.
