Github user bhaisaab commented on the pull request: https://github.com/apache/cloudstack/pull/1423#issuecomment-212062046 @syed looks like marvin plugin is missing; if you've both python 2.6/2.7 (looks like nose is using python 2.6) make sure to install it for the one you use (the default python). Alternatively, try to install using pip with --upgrade; for example, after building cloudstack run: sudo pip install --upgrade tools/marvin/dist/<the marvin pkg>.tar.gz See if this helps.
