observations:
- lxc-webpanel functions as expected
- lxc commands issued from command line interface and returns non-zero exit status 1
- functions called from lxclite module within a python interpreter raise exceptions
question:
How can I locate the missing factor that allows lxc-webpanel to function as expected? When I issue lxc commands in a bash shell or when I call the same defs that lxc-webpanel does from an python interpreter the lxc commands fail.
goal:
Be able to use the bash CLI or a python session to manage lxc containers

A container named 'test-container' was created using the lxc-webpanel.
observation 1: lxc-webpanel trial screenshots
observation 2: lxc commands from bash CLI
In:
lxc-info -qn test-containerOut:
test-container doesn't exist
In:
lxc-attach --name test-containerOut:
attach.c: lxc_attach: 635 failed to get the init pid
observation 3: lxclite def call from ipython3
- In:
import lxclite as lxc container = 'test-container' lxc.info(container)
ContainerDoesntExists Traceback (most recent call last) in () ----> 1 lxc.info(container)
../../python3_dev/_lxc/lxclite/init.py in info(container) 122 if not exists(container): 123 raise ContainerDoesntExists( --> 124 'Container {} does not exist!'.format(container)) 125 126 output = _run('lxc-info -qn {}|grep -i "State\|PID"'.format(container),
ContainerDoesntExists: Container test-container does not exist!
