RAM and other state can be part of a snapshot for VMs, in which case the VM will continue right where it was.

The state of a container is not part of the snapshot (just checked), as it is really hard to capture the state of the container (CPU, network, all kinds of file and socket handles) and restore it because all an LXC container is, is local processes in their separate cgroups. This is also the reason why a live migration is not really possible right now, as all that would need to be cut out from the current host machine and restore in the target machine.

This is much easier for VMs as Qemu offers a nice abstraction layer.
