I see frequently warning messages in the result of gate-cinder-python27.
Those messages are as below:

<Warning Message 1>
/home/jenkins/workspace/gate-cinder-python27/.tox/py27/local/lib/python2.7/site-packages/novaclient/v1_1/__init__.py:30:
UserWarning: Module novaclient.v1_1 is deprecated (taken as a basis for novaclient.v2).
The preferable way to get client class or object you can find in novaclient.client module.
