When launching an unprivileged container as a non-root user, I get this error in logs:
20250625180046.951 ERROR cgfsng - ../src/lxc/cgroups/cgfsng.c:__cgfsng_delegate_controllers:3341 - Device or resource busy - Could not enable "+cpu +memory +pids" controllers in the unified cgroup 11
This is the only error, and everything else appears to work just fine. How can I solve this (alleged) error?
systemd-run --unit=mylxc --user --scope -p "Delegate=yes" -- lxc-start -n myuplxc --logfile=/tmp/logs.log
I’m on Debian 12 (Host) with LXC 5.0.2.
