Actually I think it may be the opposite problem, at least where I'm currently running into this. oslo.sphinx is only installed in the venv and it creates a namespace package there. Then if you try to load oslo.config in the venv it looks in the namespace package, doesn't find it, and bails with a missing module error. I'm personally running into this in tempest - I can't even run pep8 out of the box because the sample config check fails due to missing oslo.config. Here's what I'm seeing: In the tox venv: (pep8)[fedora@devstack site-packages]$ ls oslo* oslo.sphinx-1.1-py2.7-nspkg.pth oslo: sphinx oslo.sphinx-1.1-py2.7.egg-info: dependency_links.txt namespace_packages.txt PKG-INFO top_level.txt installed-files.txt not-zip-safe SOURCES.txt And in the system site-packages: [fedora@devstack site-packages]$ ls oslo* oslo.config.egg-link oslo.messaging.egg-link Since I don't actually care about oslo.sphinx in this case, I also found that deleting it from the venv fixes the problem, but obviously that's just a hacky workaround. My initial thought is to install oslo.sphinx in devstack the same way as oslo.config and oslo.messaging, but I assume there's a reason we didn't do it that way in the first place so I'm not sure if that will work. So I don't know what the proper fix is, but I thought I'd share what I've found so far. Also, I'm not sure if this even relates to the ceilometer issue since I wouldn't expect that to be running in a venv, but it may have a similar issue. -Ben
