Hello Michael, When I am testing deferring skb allocation patch, I found this problem. Simply removing and reloading guest virtio_net module would cause guest exit with errors. It is easy to reproduce it: [root@localhost ~]# rmmod virtio_net [root@localhost ~]# modprobe virtio_net vhost_net_init returned -17 Any idea?
