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. Paolo
