[lxc-users] Are these messages normal for un-previlieged lxc containers?

Mon Feb 22 07:46:30 UTC 2016

OS: Ubuntu 16.04
LXC: 2.0.0-rc1

Following are from host journal when starting up a lxc container:

My main concern are those cgmanager and audit messages.

Are they normal for unprivileged container and can be ignore??
