Hi,
I experience the exact same problem. Similar setup (wily host, elementary freya
container). No user session is created when I login the desktop so polkit won't
grant elevated privileges.
In the container, /proc/1/cgroup shows:
10:cpu,cpuacct:/lxc/topaze
9:freezer:/lxc/topaze
8:devices:/lxc/topaze
7:memory:/lxc/topaze
6:cpuset:/lxc/topaze
5:net_cls,net_prio:/lxc/topaze
4:hugetlb:/lxc/topaze
3:perf_event:/lxc/topaze
2:blkio:/lxc/topaze
1:name=systemd:/lxc/topaze
In the container auth.log, I see those lines:
Jan 24 15:20:09 topaze systemd-logind[1739]: cgmanager: cgm_list_children for
controller=systemd, cgroup_path=lxc/topaze/user failed: invalid request
Jan 24 15:20:09 topaze systemd-logind[1739]: New seat seat0.

Jan 24 15:20:11 topaze lightdm: pam_systemd(lightdm-greeter:session): Failed to
create session: Invalid argument
The container runs cgproxy.
On the host, cgmanager reports:
jan 24 15:20:09 opale cgmanager[952]: cgmanager: Invalid path
/run/cgmanager/fs/none,name=systemd//lxc/topaze/lxc/topaze/user (No such file
or directory)
jan 24 15:20:09 opale cgmanager[952]: cgmanager:list_children_main: Could not
determine the requested cgroup (systemd:lxc/topaze/user)
jan 24 15:20:09 opale cgmanager[952]: cgmanager: Error getting children for
systemd:lxc/topaze/user for pid 2095
Does anybody have a hint on what causes this cgroup path duplication
(lxc/topaze/lxc/topaze)? I suspect it may have something to do with the issue.
Thanks
Alain.
