Problems with removing CPU limit on a running CT via API

[dmemsm]

Hello, I'm using Proxmox VE 8.2.4. I get an error when trying to change the CPU limit to 0 on a running CT via the API: unable to hotplug cpulimit: closing file '/sys/fs/cgroup/lxc/101/cpu.max' failed - Invalid argument.


This error only appears when I try to disable CPU limit by setting it to 0. If I want to change it to some other value, then everything works fine.

I also found this thread on forum: https://forum.proxmox.com/threads/issue-with-removing-cpu-limit-from-running-vm.97799/, but in my situation removing CPU limit on a running CT via web interface works fine, error appears only when using API.


Is it a bug or am I doing something wrong?

How exactly are you trying to set it to 0 - which APIclient/curl arguments are you using?

The GUI sends 'delete: cpulimit' as parameter (which works).
