Nice write up!

Why not put 'preserve_srcdir = True' by default?
In general, you can simplify the documentation by using the most 
frequent use case at the beginning. For example, you can just point to 
another link to get you all the yum dependencies instead of adding it 
here in this page where they do not belong.

The get_started.py script is cool :)

Note that in your output screendump is not functioning.

The setup was really neat and the tests managed to execute easily. I did 
got some failures and exception below:
