**Running Tests from Shared Folders**
If you are running the unit tests from a shared folder, you may see tests start
to fail or stop completely as a result of Python lockfile issues [#f4]_. You
can get around this by manually setting or updating the following line in
``nova/tests/fake_flags.py``::
FLAGS['lock_path'].SetDefault('/tmp')
Note that you may use any location (not just ``/tmp``!) as long as it is not
a shared folder.
