I'm not sure if this will help the KVM camp at all but I have a very similar situation. I have a Radeon 7970 and a Xonar DX which uses the same chipset and pci-pcie bridge. The best I could get passthrough to work in KVM was exactly the same as the original poster's experience. I eventually got the 7970 working in the guest but it would not reset properly on guest restart or shutdown. After getting frustrated with my experience I decided to try Xen. To my surprise both the 7970 and the Xonar DX worked perfectly on the first try and performance was excellent. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
