Could you please confirm, preferably on-list, whether the patch makes the errors go away for you with userspace virtio? However, as I said previously, it's good to fix them but I think they are unrelated to the fact that vhost does not work for you. Shirley, if you have the time, please send details on your setup and observations on tcpdump output in both guest and host with vhost enabled. Thanks! -- MST
