It is possible to hibernate an LXC container?
Solution 1:
You want lxc-checkpoint, which is not yet implemented, at the time of writing (Jun 2014).
checkpoint the specified container NAME and dumps its state into the file FILE. If the option --pause is specified, the application will be stopped after the checkpoint just before resuming execution. The command lxc-unfreeze will resume its execution.
Actually, this command does not operate. Its description helps to define a CLI api for future Checkpoint / Restart solution
