Can not suspend LXC


Nov 4, 2011
Hello everybody,

I have an error when suspend LXC with API Proxmox.

Error log:
lxc-checkpoint: criu.c: criu_version_ok: 699 must have criu 2.0 or greater to checkpoint/restore
Checkpointing 27692769 failed.
TASK ERROR: command 'lxc-checkpoint -n 27692769 -s -D /var/lib/vz/dump' failed: exit code 1

Maybe i need to upgrade CRIU 2.0. How to i can upgrade criu in proxmox ?

Thanks a lot.
I am sorry, but checkpoint/restore for containers is not really implemented and tested ...
There is still no plan to integrate that. I suggest that you use VMs if you need that feature.

Would be great if Proxmox integrated that feature : I have a Proxmox laptop with a container that takes a few minutes to boot up, so "hibernating" it before I have to shutdown / reboot my laptop could save me some time at boot.

Right now the only solution is to manage the container directly (i.e. no Proxmox), and use LXC's native checkpoint feature (, or the CRIU project (
