Bug Description

OS: Ubuntu 14.04.2 LTS
Ironic version: master branch, commit: 6e714ffb6c84913ed53e647f7637da3a936ab1fa

Upon attempting to enable the UCS drivers in Bifrost, I encountered two issues:

1) The documented UcsSdk version fails to install from pip. Although, a slightly newer revision was released a few days ago, so I attempted 0.8.1.7 which does successfully install.

  Downloading UcsSdk-0.8.1.6.tar.gz (2.7MB)

    (See the setuptools manual under "Namespace Packages" for details.)

2) Upon adding the agent_ucs driver to the enabled drivers line in the ironic.conf and restarting the conductor service, the logs below were observed in the conductor log. The root cause appears to be rooted in a file in the initial commit of the SDK. https://github.com/CiscoUcs/UcsPythonSDK/blob/master/src/UcsSdk/Constants.py#L1596

WORKAROUND:

So the __init__.py from UcsSdk is missing. As a workaround you can copy that __init__.py and then the ironic-conductor will load the driver (run as root):

# curl https://raw.githubusercontent.com/CiscoUcs/UcsPythonSDK/master/src/UcsSdk/__init__.py > /usr/lib/python2.7/site-packages/UcsSdk/__init__.py

Now restart the Ironic conductor service.
