Yes. Our virtualenvs are currently configured to not allow system
packages to be used (so that they only use python libs installed into
the virtualenv. However, libvirt is not installable via pip, which is a
problem.

We've recently added a new tox environment to help with this, so try
running:

tox -v -efull

Which is set up to allow system site packages.

However, if you're adding unittests, you should look at the other ones
which test for libvirt existence and skip the tests if they can't find it.
