Containing container memory

Snapshots and live migration with CRIU

This talk is about how CRIU deals with application memory during container checkpoint, restore and live migration. We present techniques we use to create exact snapshot of a process memory layout during checkpoint and then how we recreate that exact layout at the time of restore. We present optimizations for reducing the snapshots footprint and for making container live migration livelier.
