LXC + CRIU

Status, future work

Tycho.Andersen @ Canonical .com

What exists today?

$ lxc-checkpoint --help
  • frontend for criu
  • manages network bits
  • mounts rootfs correctly
  • error checking for unsupported configurations
  • reattaches so other lxc-* tools work

Future work

  • Support all filesystem options
  • Support criu's pre-dump
  • Better checking for unsupported things
  • General predictability

Demo

Thanks!
