Common issue is that la inside LXC shows hosts's loadaverage.

As solution, LXC provide option: -l, –enable-loadavg Enable loadavg virtualization.
This feature doesn't add to the isolation at all. `sysinfo()` will return the host information even when in a container.
[Service] ExecStart= ExecStart=/usr/bin/lxcfs -l /var/lib/lxcfs
NOTE: After restarting lxcfs.service, running containers lost /proc access. Restart of containers is required.
systemctl restart lxcfs
