I think I last tried it with CRIU 0.8 without much success but I took an action item during Ubuntu's planning even last week to try with a newer release and get in touch with Pavel if I'm still having issues. From what we discussed at Linux Plumbers, CRIU should indeed let you dump a full container and restore it on the same machine or on another so long as the filesystem and any other external dependency of the container matches. If I can get this working and they've resolved a few of the known issues (specifically the fact that it'd only build on x86_64), then the plan is to add API calls to LXC's API that'll implement the checkpoint/restore feature using CRIU. -- Stéphane Graber Ubuntu developer http://www.ubuntu.com
