Interesting...  I tried something similar using KOAN/Cobbler and believe 
that is the error I saw as well...

The only thing that does work is if I install Fedora 11 and then perform an upgrade to Fedora 12.  I really don't want to have to deploy machines this way.
> Is anyone else experiencing this issue?  I can provide any further information requested.  Basically, to repeat my error, install CentOS 5.4 with Virtualization, then try to install a Fedora 12 domU.  The installation finishes without error but you can't boot.  The systems are all x86_64.
