CPU affinity for LXC containers setting?

[Giovanni]

Hi, I found the "CPU affinity" (cpu pinning) setting for VMs inside hardware panel in proxmox but I am unable to find this setting for LXC containers.
How can I pin a specific LXC container to specific CPU cores in PVE 7.3.3?

Hello,

currently there is no way to do this in the GUI, but you can achieve this by editing the container's configuration file [1]. The configuration files are stored in /etc/pve/lxc.

thank you!
TL;DR

add to 101.conf of the lxc container. I hope this feature makes it to web GUI soon.

lxc.cgroup2.cpuset.cpus: 0-10
