This switches to the new facility with stages and introduces per-flow
migration, with a simple structure roughly based on struct
tcp_tap_conn.
I tested this: a simple connection between socat and nc with some text
works (again) for me. Sequence numbers (of course), window parameters,
and MSS all match.
However, it *is* draft quality and *it might contain bugs*.
It also contains a lot of TODO items, missing comments, probably
some left-overs, and so on.
David Gibson (2):
migrate: Make more handling common rather than vhost-user specific
migrate: Don't handle the migration channel through epoll
Stefano Brivio (4):
Introduce facilities for guest migration on top of vhost-user
infrastructure
Add interfaces and configuration bits for passt-repair
vhost_user: Make source quit after reporting migration state
Implement source and target sides of migration
