FYI, I have a follow up series (~20 patches,
https://github.com/elmarco/qemu/tree/vhost-user-reconnect) doing
mostly cleanups and extra checks for disconnection at run time. In
particular, it should avoid some obvious crashers/asserts, and
prevents qemu from running as long the initial vhost_user_start()
didn't succeed (so initial flags are set). I would like to know how to
proceed with the follow-up: should I resend the whole series or should
we review/merge this rfc first (even though it is known to be
incomplete in many disconnect cases that the follow up fixes).
thanks
