OCI runtime error: unable to start container: crun: cannot set memory swappiness with cgroupv2

[Bush-cat]

Issue Description

To update my Containers I recreated them, but after they were created, most couldn't start anymore. 4 out of 7 of my Containers got that Error.
I guess the other Containers do not have a swappiness flag. Or is it possible to globally disable only swapiness since cgroupv2 doesn't allow it. Or should I use cgroupv1 instead, is it posible to set cgroupversion per Container? I tried podman updatebutit requiresthe container to be running.
Everything worked before, I'm not sure if podman used cgroup v2 before or it changed with podman v5 or decided to use it with a kernel update

Steps to reproduce the issue

cgroupv2 doesn't allow you to set swappiness so I suggest you simply remove that setting. The cgroup version is defined globally and depens on the system configuration.

I think you can still configure swappiness globally via sysctl.

I didn't configure swappiness, yesterday I recreated the containers again and they are working now, I'm not sure how they got the swappiness configuration

[rhatdan]

Did you create the containers with an older podman and then update or switch to cgoupv2?

[Bush-cat]

possible, I was running podman v4 before, I'm not sure when I updated podman since it happens automatically in opensuse microos
