In Xen 3.4.x and below, xend would assume the configuration file was a
python module and you were therefore allowed to use python statements
and constructs to describe the configuration options dynamically.  If
using that config file is a must, then you should use xend just as
before. Otherwise, you should read the guide to Xen 4.1 from the link
below:
