Since we are python3 only for openstack we create a single python3 virtualenv to install all the packages into. This gives us the benefits of installing into a virtualenv while still ensuring coinstallability. This is a major change and will likely break many things. There are several reasons for this. The change that started this effort was pip stopped uninstalling packages which used distutils to generate their package installation. Many distro packages do this which meant that pip installed packages and distro packages could not coexist in the global install space. More recently git has made pip installing repos as root more difficult due to file ownership concerns. Currently the switch to the global venv is optional, but if we go down this path we should very quickly remove the old global installation method as it has only caused us problems. Major hurdles we have to get over are convincing rootwrap to trust binaries in the virtualenvs (so you'll notice we update rootwrap configs). Some distros still have issues, keep them using the old setup for now.
