apt-get operates with system-level packages, so there's no
difference if you run it from virtualenv or not.

I think you have two options:

- Install python-libvirt and create virtualenv with
  --system-site-packages [1] so it pulls system python-libvirt

- Activate virtualenv and install python-libvirt using pip
