Good job, the koan issue is resolved.   You now have a straight up Xen 
issue, which should be directly reproducible by using virt-install, so 
here are some initial thoughts:

Initial thoughts:  

- Make sure you're using a Xen kernel and initrd, rather than the normal 
one.   This comes out of the "xen" directory on a CD, not the "pxeboot" one.
- Check the logfiles (/var/log/xen/*) for anything suspicious
- If all else fails, ask fedora-xen at redhat.com
