Hello,
I am reporting a blocking issue for any external integration on my Khadas VIM1S (Ubuntu 24.04, kernel Amlogic 7.0.0+).
Symptom — unable to start an external integration (tested with Shelly), error in the logs:
Cannot restart container XXX: ... error setting cgroup config for procHooks process:
openat2 /sys/fs/cgroup/.../cpu.max: no such file or directory
Isolated cause, reproducible outside Gladys:
bash
docker run --rm hello-world # OK
docker run --rm --cpus="1.0" hello-world # fails with the same error
Kernel confirmation :
bash
cat /boot/config-$(uname -r) | grep CFS_BANDWIDTH
→ CONFIG_CFS_BANDWIDTH is not set
This kernel compile flag provides cpu.max (CPU quota cgroup v2). Without it, no --cpus limit can be set on a container — so as soon as external integrations apply this limit at creation, it systematically fails, with no possible workaround on the system config side (tested: cgroup driver systemd and cgroupfs, cgroup delegation verified correct at all levels).
Potential scope : this is not isolated to my hardware. The Raspberry Pi has historically had the same issue (ticket raspberrypi/linux#3387, still open).
Suggestion : make the CPU limit optional, or switch to --cpu-shares (weighting, does not require cpu.max) rather than a strict quota — or detect the absence of cpu.max and create the container without a limit rather than failing.
I remain available to test on this hardware if needed. Thanks
