I add that on the proxmox node I can find the following logs:

Seems an apparmor problem... furthermore seems that old LXC doesn't
suffer of this problem but if I create a new LXC it does.

------------------------------
On a proxmox 6.4 environment, when a user log on to a specific LXC
container machine named unifi-controller, the logon time is very slow
and on the host logs I find:
Sep 02 07:15:36 unifi-controller systemd[1978474]:
systemd-logind.service: Failed at step NAMESPACE spawning
/lib/systemd/systemd-logind: Permission denied
Sep 02 07:15:36 unifi-controller systemd[1978474]:
systemd-logind.service: Failed to set up mount namespacing:
/run/systemd/unit-root/proc: Permission denied
Other LXC doesn't have any problems. Someone can help me to find the issue?
Best regards
Piviul
