[SOLVED] Issue with removing CPU limit from running VM

[leesteken]

I'm using the enterprise repository, currently running a Proxmox version 7.0-11.
Setting or changing the CPU limit of a VM via the Proxmox web GUI works fine. But removing it, while the VM is running, results in the following message:

Parameter verification failed. (400)

cpulimit: hotplug problem - closing file '/sys/fs/cgroup/qemu.slice/100.scope//cpu.max' failed - Invalid argument

My guess is that a numerical argument is expected by some part of the software but the syntax for the content of those files is max when unlimited.

yes, thats a bug. sent patch fixing it to pve-devel: https://lists.proxmox.com/pipermail/pve-devel/2021-October/050355.html

I only now noticed that the fix has reached enterprise repository and it resolves the issue.
