This is very strange, as I have libvirt installed on my development machine and these unit tests pass for me. Can you try rebuilding your venv and see if that fixes the problem? In fact, are you using a venv at all?

Hi.
This bug was seen without venv on centos 6.4.

Confirming because there appears to be enough information to reproduce (or not) - run tests on CentOS 6.4 with libvirt installed.

Also, testing without a venv is not really valid for unit tests.
