VFIO is Linux-only, and in theory will be able to work on the guest, but no= t at the moment, since it requires IOMMU. There was a GSoC proposal for KVM= to do IOMMU implementation, and there were a few AMD IOMMU-emulation patch= es floating around the KVM lists for some time, but nothing has made it int= o release yet.
