Maybe an RFC to see? I will try to hack up an RFC that involves vsock and net so we can discuss the approach. Unfortunately I currently have a lots of other (non-development) stuff on my plate, please bear with me. I suggest to go forward with this patch for fixing vsock, and look if we can do something better for the rest. By the way in the thread with Stefano, I've raised a question about live migration (i.e. what would happen of someone were to implement packed layout for vhost and make add the feature to vhost/net). I would very much like to have your opinion on that! Regards, Halil
