William,
Sorry I am late to respond.. and I also further apologize as I seem to have misread your request.. I missed the part about koan, unfortunately I've never used koan to provision in my setup, I like you had too many issues getting it working right. Instead I used scripts that acted directly with ESXI CLI, kvm (virt-install), etc. to boot new virtual machines, which would then install the default profile via pxe boot, self register with cobbler and then reinstall to the appropriate OS/settings (based on settings within the default profile, and or script, which I changed depending on the install.)
I looked through my files, and I have some of my scripts, but I don't have any of the cobbler settings themselves.
If possible could you provide the output for any errors that you are getting? I could help you take a look (it would also be nice to finally get around to learning koan... :) ).
Respectfully,
Scott
(((FYI, (although it's not related to your issue) I am also
attempting to build a potential upgrade to cobbler that will hopefully
allow OS/Configuration for rack-scale installations based on
switch/switchport of the installed server,)))
