MSI-X is a default mode for NetKvm and viostor on Vista and forward.
It must work. Just make sure that CPU family is 0xf or higher, otherwise
Windows will not activate MSI-X.

Speaking of which, I asked Asias about this recently and he seems to
think that virtio-net + virtio-blk drivers for MSFT do in fact support
MSI /MSI-X.
MST, do you know if that that true..?
