Open Stack

Hi,


Facing "Could not determine a suitable URL for the plugin " Error during 
stacking.
issue is seen only after repeated stack , unstack in a setup.
It will be fine 10 to 15 CI runs later it is starting throwing below error.
I am able to consistently reproduce it

2016-01-11 06:28:06.724 | + '[' bare = bare ']'
2016-01-11 06:28:06.724 | + '[' '' = zcat ']'

create cirros-0.3.2-x86_64-disk --public --container-format=bare 
--disk-format qcow2
