Sorry your answer came late, so my reply too ;). It may depend on the
use case, what I suggest wouldn't need to stop the VM, but merely set
the link-down status. Furthermore, how do you disconnect/deactivate
the backend cleanly? Having an explicit message for that and document
it may make things easier.

It has been a while I haven't looked at vhost-user, so I am short of
details, but I rebased this series, if there is still interest. I'll
send a RFCv2, there are a couple of worthy fixes to pick from that.

thanks
