[CRIU] help for podman checkpointing

[yifan lu]

Hello, I'm doing some research on container C/R, then I choose criu and
podman. However, I got the similar issue with
https://github.com/containers/podman/issues/13672. How can I solve this?

The experiment env is as follows:
CRIU 3.17.1
Podman 4.3.1
runc 1.1.12
kernel 6.1.0(Debian 12.5)

The result of "criu check --all" is "Looks good."
(When I do the same on criu 3.19, the output became "Looks good but some
kernel features are missing which, depending on your process tree, may
cause dump or restore failure."
I'm confused with the missing kernel features and what to inspect for the
detail.)

Thanks for your help.
