I was trying to to check how criu works with podman and each time getting same error - 

➜  ~ sudo podman run -d --name httpd -p 7000:80 docker.io/httpd

Error: configured runtime does not support checkpoint/restore

OS - Ubuntu 23.10

That is pretty easy:

Error: configured runtime does not support checkpoint/restore

My guess is that crun is built without CRIU support on Ubuntu. Try Fedora, we know that crun supports CRIU there.

On Ubuntu you could also try to switch to runc.

Hi @adrianreber actually I was working on this issue - https://github.com/checkpoint-restore/checkpointctl/issues/77

and I just wanted to check how criu works with checkpointctl, is there any way to see that on ubuntu system?

Try to use runc instead of crun.
