Agreed. I'm pretty sure it's the scenario that I posted in my other
reply to this thread.
The common virtio-scsi code in QEMU should guard against this. In
virtio-blk data plane I hit a similar case and ended up starting the
data plane thread (equivalent to vhost here) *before* the status
register is set to DRIVER_OK.
