Huh. Running a more recent Xen release with an older kernel on Fom0 is 
kind of begging for incompatibility, I'd suspect.
What is in /var/log/xen/*? And what does "yum list extras" say, in case 
you pulled non-FC6 or non-FC7 packages while working with things? And 
have you tried building any new images and looking for differences in 
the config files? FC6 was xen 3.0.3, FC7 is Xen 3.1.0.
