I think I know what is going on.

It's not hanging, what is happening is that the virtualized console no 
longer becomes useful once the VNC graphics mode engages -- in other 
words, you should be able to watch the rest of the install with 
virt-manager.

Older versions of koan had a flag to disable VNC support, but this was 
missing in recent versions (because I was not aware of the virt console 
issue).  In newer versions of koan (such as the test builds... 
http://cobbler.et.redhat.com/download/testing) there is once again a 
--nogfx flag.

When this flag is used, the installation will happen entirely in the 
virt console (and is watchable in text mode), though you will not be 
able to get VNC graphics at the same time.

qemu/KVM (another virtualization type cobbler supports) does not support 
the --nogfx flag.

I suspect most folks using VMs in an automated context would want to 
disable the VNC/graphics bits so that they could use the text consoles.

Since koan in the "testing" directory does not contain any new features 
that require the newer cobbler, I can look at releasing this version 
(with the --nogfx flag) in a few weeks to Fedora/EPEL.
