This is logging in as root?
Yes. This log was recorded by logging in with root.

I found there is something like error "cgmanager:get_pid_cgroup_main: Could not determine the requestor cgroup". root@myhost:~# tail -f /var/log/upstart/cgmanager.log UPSTART_JOB=cgmanager TERM=linux PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin cgmanager_opts=--debug PWD=/ cgm_extra_mounts=-m name=systemd,name=container,name=fairsched,name=beancounter Mounted systemd onto /run/cgmanager/fs/none,name=systemd found 1 controllers buf is /run/cgmanager/agents/cgm-release-agent.systemd Mounted systemd onto /run/cgmanager/fs/none,name=systemd Connection from private client GetPidCgroup: Client fd is: 6 (pid=442, uid=0, gid=0) cgmanager:get_pid_cgroup_main: Could not determine the requestor cgroup Disconnected from private client Connection from private client Create: Client fd is: 6 (pid=442, uid=0, gid=0) Created /run/cgmanager/fs/none,name=systemd/user/0.user/c2.session for 442 (0:0) cgmanager_create: returning 0; existed is -1 Connection from private client Disconnected from private client MovePid: Client fd is: 7 (pid=442, uid=0, gid=0) 963 moved to systemd:user/0.user/c2.session by 442's request Connection from private client Disconnected from private client Chown: Client fd is: 6 (pid=442, uid=0, gid=0) Chown: Client fd is: 6 (pid=442, uid=0, gid=0) Connection from private client Disconnected from private client Chown: Client fd is: 7 (pid=442, uid=0, gid=0) Chown: Client fd is: 7 (pid=442, uid=0, gid=0) Disconnected from private client > > This error message is written even if I log out before reboot is executed > > or I execute reboot via control panel which is outside of ubuntu system. > > > > > The message may be ignorable - the real question is, when you > > > login, do you get a custom cgroup?

But the log "failed: invalid request" is still written. Here's my current /etc/default/cgmanager: root@myhost:~# cat /etc/default/cgmanager cgmanager_opts="--debug" env cgm_extra_mounts="-m name=systemd,name=container,name=fairsched,name=beancounter" root@myhost:~# Regards,
