RE: [Xen-users] Re: PCI Passthrough to Windows DomU

Hi,

Only the very latest AMD boards using the AMD SR56X0 chipsets (Or to be more 
specific the SP5100 southbridge that goes with them) support PCI Passthrough. 
Here are a couple of examples:

I suspect you need a fairly recent kernel and Xen version for these boards to 
work but maybe someone on the list knows the specifics.

Afaik there are no AMD boards with an IOMMU capable of passing through 
devices to an HVM guest, so Vt-d (which is an Intel-term) is your only 
choice for now.
Supported (or better "working", since almost no vendor gives official 
VT-d support with Xen) boards can be found here:
