Re: [Xen-users] PCI Pass through on AMD with HVM?

Hi Greg,

There is currently no way of passing PCI devices to a HVM DomU on AMD  
platforms, because they don't have an IOMMU. People (including  
myself) have been waiting for this feature for quite a while now, but  
as of now, the first AMD CPUs, that implement it are supposed to be  
released early 2009 as far as I know.
Cheers,


Paul.
