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 ... (XEN) AMD SVM: ASIDs disabled.

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

-----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.

I have a SUN ULTRA 40 - M2 running AMD CPU0: AMD Dual-Core AMD Opteron(tm) Processor 2218 stepping 03 and IOMMU is enabled on BIOS but i still get (XEN) I/O virtualisation disabled. IS there anything i am missing ? Is IOMMU a cpu feature or a motherboard feature ?
