Well, it seems there is no luck!! eventhough I thought this CPU was the
right for me, I made a bad move, or at least the svm
that this CPU supports it's not enough.
So, as for your comment, it seems the vt-d it's an intel feature only?
no way to export pci devices to DomU's using AMD?
Thanks for yor time and support..
