You're right, I meant to the dhcp and install tree managed by cobbler

It just logs  "Creating guest from" and then the xml configuration, 
which seems ok except for the bridge being xenbr1 instead of xenbr0, and 
then "Saving XM config file '# Automatically generated xen config file", 
and the file that gets saved in /etc/xen.

It's serving on eth0 - if I could change the virtual-bridge to xenbr0, 
it should work, right?

Yes, but only Fedora 8 shuts down. CentOS 5 just can't connect to the 
(virtual) network.

Oops! "It's the version mismatch, stupid!" :)

I must have installed cobbler from epel-testing and koan from epel...

It's working now, thanks!
