If "consistent" = "you get the same state as power failure on a physical
server, which most database can recover from using some kind of journal
replay", then it should be storage-level snapshot. This requires that the
containers use a storage which can support a large number of snapshots
without degrading performance (e.g. btrfs or zfs).

If "consistent" = "vmware/virtualbox's snapshot/resume feature", then AFAIK
there's no perfectly reliable way to do that in lxc yet. There's
http://criu.org/LXC , but it still have some limitations.
