Yes sir, did it after the upgrade to 6.11.0.
This was my first play around with lxc and was looking at moving some VMs to containers instead.
Was really hoping that cpu and memory limits would be visible in container, which doesn't seem to be the case.
From this: https://discuss.linuxcontainers.org/t/limitations-not-applied-inside-of-containers/11395/3
Just tried lxc.cgroup2.memory.max = 4G and it at least allows me to start the container, I think the limits are enforced as I tried to make a 4G file in /run and the container died
