Linux 6.6 EEVDF scheduler on Kubernetes: openat2 /sys/fs/cgroup/kubepods.slice/cpu.weight: no such file or directory

[chenk008]

What happened?

Linux 6.6 comes with a new job scheduler called EEVDF (Earliest Eligible Virtual Deadline First), replacing the old CFS.

The kubelet/containerd failed to create cgroup

What did you expect to happen?

Kubelet/containerd is compatible with linux EEVDF scheduler

How can we reproduce it (as minimally and precisely as possible)?

Run kubernetes on Ubuntu 24.04 LTS

Anything else we need to know?
