[libvirt] [RFC PATCH 1/4] configure: Include support for CRIU
Checkpoint/restore in User-space [1] enables the current running state
of lxc containers to be stored as a set of image files. Then, one could
restore the container to its previous state (before checkpointing) on
the same or another system.
