Quoting Robert Pendell (shinji at elite-systems.org):
> OS: Ubuntu 14.04 LTS x86_64
> Kernel: Host-Supplied 3.14.1
> Provider: Linode
> Host Virtualization: Xen Paravirtualized
> LXC Version: 1.0.3-0ubuntu3
> 
> When I attempt to boot an unprivileged container I get the error
> "lxc_container: command get_cgroup failed to receive response".  This
> appears to be due to missing cgroup however it is mounted and is using
> cgmanager as was recently changed (output seen later).  For
> troubleshooting I switched to the distribution supplied kernel (host
> supports pv-grub) and it does the same thing.  Host has apparmor
> disabled and when I was running the distribution kernel I verified
> that apparmor was enabled and running so in this case it made no
> difference.
> 
> I was able to run a privileged container even with the host-supplied
> kernel however this won't meet my individual requirements.
> 
> Any assistance will be greatly appreciated.
