The add_virtualhost calls insert key/values into a dictionary. The key is 
the first parameter to the add_virtualhost call and the value is the second 

You are not generating three entries in the dictionary with your 
add_virtualhost calls. The effect is as if the first two were not made and 
the only virtual host you are defining is the last one.

This might be part of your problem.
