[et-mgmt-tools] Xen System builds using Koan

[Jason Hartley]

First off, I really like the design of Cobbler and Koan.  I especially
like the kickstart templates and the flexibility that the templates give
you.  The only problem is that I am having trouble with the issue below
and would appreciate any kind of help.

I have a Centos 5 system that I have setup as a Xen host.  I have setup
the EPEL repository and used it to install Cobbler version 0.4.8-1,along
with koan 0.4.0-1.  I have successfully used the tutorial at
http://cobbler.et.redhat.com/cobbler-import.php with a few modifications
to build a Xen guest using the default profile for Centos 5 that is
created when you import from the Centos 5 DVD.  When I attempt to build
from a system definition that I have built from the default profile I get
the below error. I have started to dig through the code, but would like
some direction in debugging the problem and maybe a push in the right
direction on what might be wrong.
