Public bug reported:
I'm trying to migrate an OS running on a physical machine to an LXC container,
but no luck so far. Right now the system gets stuck somewhere during lxc-start:
<...>
* Stopping cgroup management proxy ...done.
* Starting load modules from /etc/modules ...done.
* Stopping Mount network filesystems ...done.
* Starting set sysctls from /etc/sysctl.conf ...done.
* Stopping set sysctls from /etc/sysctl.conf ...done.
* Stopping load modules from /etc/modules ...done.
* Starting configure network device ...done.
* Starting Bridge socket events into upstart ...done.

Both host and guest are running ubuntu 14.04 LTS and same guest boots
properly via VirtualBox... kern.log shows some issues with mounts:
