Re: [Xen-users] PCI Pass through on AMD with HVM?
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
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.

I have gone through the lists as well as google and can not find
the answer. All I could find for info was some posts from 2006 and
early 2007 indication the AMD IOMMU was comming soon.
Is it possible to get PCI pass through running on HVM with AMD (X2
4200)?
I can get my apps running in hvm but pass through.
xm dmesg

I'm not sure if my processor is not capable or if it simply does
not work with AMD.
Any help would be appreciated.
Greg
