The virtio transport separation in QEMU is something I mean to look
into.  I've talked with Anthony in the past about the transport (e.g.
PCI) providing a virtio bus, which allows us to reuse qdev/QOM in a
more natural way.  Today the hw/virtio* code is glued together in an
ad-hoc way.  9pfs has started to factor out the virtio-9p-pci device.
It's time to put a good solution in place for all virtio devices.
