I'm not sure if vfio covers your needs completely, but I tested it here very successfully. I was able to create a patch, which can be applied to opensuse 3.4.1 kernel and which seams to run well. I even managed to integrate it into libvirt :-). So it is usable as every other traditional VM, too. Besides the problem with AMD IOMMU, which requires to unbind a whole group of devices in some cases (PCI passthrough - not PCIe), it's really cool! And it's usable now!
