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. -- MST
