It prints out: <module 'virtinst' from 'virtinst/__init__.py'>""

I checked again, and see that virt-install was installed into
/usr/local/bin, which might not be the right place? It should be in
/usr/bin, right? So how to install virt-install there?

If that matters, I install virt-install by running "python setup.py
install". I am on Ubuntu 904, and I heard that Python 2.6.2 on this
distro has some problems with installation, so that they always put
code into /usr/local/ (??)
