libvirt users - Mar 2014 - Re: [libvirt] Python-libvirt in a virtual environment.

@Michel
using virtualenv we can create an isolated environment in the system.
Just go through - http://docs.python-guide.org/en/latest/dev/virtualenvs/
@Eric
I'm using Ubuntu, and I was able to install and use libvirt using sudo
apt-get install python-libvirt but its not available in tg2 virtual
environment.

Moreover if you try to install in the virtualenv using the sudo apt-get
install python-libvirt, it would say  the package is been already installed.

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

1:

I installed libvirt 1.2 tarball and then I use pip install libvirt-python
inside virtual env.. it worked..

thanks
