Code review comment for lp:~salvatore-orlando/nova/bug723301

Thanks for this Salvatore! We've need this for a while now.

Could only find a few things to pick on ;-)

PEP8 / Style nit-picks:

96 import os
97 +import sys
98 import pickle

pep8: sys should come after re in this list

351 import subprocess
352 import tempfile
353 import uuid
354 +import sys

Same thing
