Another question: (6) vhost-user + "read-only" property acts a bit strangely. After opening virtio-blk-vhost-user it throws an EROFS error if you try to "blkio_start" it. However if you set the "read-only" property to true then it's OK to start it, and subsequent read operations work too. I would expect that any device can be started without needing to set this property, and in general I don't understand why vhost-user is r/o since everything I read about it seems to indicate it's a general purpose writable protocol.
