I'll merge this on the virtio 1 branch shortly.

That branch still needs some work.
I hope to have things in mergeable state end of may.
In particular
- the way we have structured breaks migration and
  makes supporting it properly tricky, so I'm refactoring
  some code.
- virtio 1 spec forbids devices from accessing memory
  until DRIVER_OK is set, but we also need to support
  legacy guests which trigger ready state by kicking some ring.

Do you need some bits from master on that branch?
I could rebase it if it's helpful.
