== P.Haul: live migrating with CRIU ==
Pavel Emelyanov, man in a red T-shirt with microphone
* Process-Haul (like U-Haul, but about processes) See http://criu.org/P.Haul
* CRIU is a part of solution for live migration of containers
* CRIU part of live migration: perform nodes compat checks, pre-dumps in a loop, copy fs if not shared, don't forget container config
* P.Haul migrate container is two steps
* More information about P.Haul: written in Python, source code https://github.com/checkpoint-restore/p.haul/, can migrate OpenVZ container (How-to https://github.com/checkpoint-restore/p.haul/blob/master/test/mtouch/HOWTO), call rsync on chroot-ed container
* P.Haul future: Docker/LXC support, smarter interations, shared FS autodetection, post-copy live migration, send images over the wire (CRIU)
* Discussion of P.Haul started
LXC has a similar concept, but slightly different. Consensus seems to be easy to achieve as to how to merge (it just needs coding effort).
Predump allows process to continue running, vs full dump which is a freeze
