Xen users - May 2006 - Network and first domu installation

I would like to use on my notebook XEN just as an add on sometimes. 
Therefore I would like to get Dom0 also able to have networking ability. 
How can I do that? (I know it is designed for security reason not to do so)

I tried all variations of config files  in /etc/xen/examples to boot 
from cd and install a small Linux version (puppy). It just does not 
start. Puppy usually runs from the CD, however, if I can get XEN to 
work, I could install it to the hard disk.


All example config files at a glance:
