[Touch-packages] [Bug 1378738] [NEW] guest os boot stuck with mount operation error
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:

Re: [Touch-packages] [Bug 1378738] [NEW] guest os boot stuck with mount operation error
Thanks for reporting this bug. To fix the cgmanager issue, add the line
lxc.mount.auto = cgroup:mixed
to your container configuration file.
That shouldn't explain your hang however. Assuming it doesn't, please
run
lxc-start -n container -l trace -o debug.out -- /sbin/init debug
verbose --debug --verbose
And append both the console output and the file debug.out
