[Bug 1267242] [NEW] Running lxc-ls as non-root should provide a nicer error message

[Jorge O. Castro]

Public bug reported:

You need root to run lxc-ls now, but this happens:

jorge at jilldactyl:~$ lxc-ls
lxc: Permission denied - opendir on lxcpath
Traceback (most recent call last):
  File "/usr/bin/lxc-ls", line 200, in <module>
    for container_name in lxc.list_containers(config_path=lxcpath):
  File "/usr/lib/python3/dist-packages/lxc/__init__.py", line 390, in list_containers
    config_path=config_path)
ValueError: failure to list containers

I asked Serge:

<hallyn> jcastro: you have to run lxc-ls as root now
 jcastro: however, it shouldn't give you a backtrace like that, just a nice error msg
<hallyn> so that's bug-worthy
