Great, I'll prepare a patch to virtio then sketching the solution that
Conny agreed with.

While Fam and I agreed that patch 1 is not required, I'm not sure if the
mutex is necessary in the end.

So if Tu Bo can check without the virtio_queue_host_notifier_read calls,
and both with/without Fam's patches, it would be great.
