Comment 2 for bug 803186

This bug was more or less just a quick placeholder to link the branch for fast merging. We had already figured out the solution by this point.

The problem was nova-api was unable to import nova.services when attempting to start outside of the development branch (preventing nova-api from running entirely). If you were to install the package using setup.py (or any other real package) this would have gone unnoticed, since the modules would be in the python path.
