I would need to see more logs to be sure, but I would guess pygrub is 
missing at least one update and this one
http://xenbits.xenproject.org/gitweb/?p=xen.git;a=commit;h=d513814db6af2b298b8776d7ffc5fb1261e176f4http://xenbits.xenproject.org/gitweb/?p=xen.git;a=commit;h=d513814db6af2b298b8776d7ffc5fb1261e176f4
is a possibility. You could test if it is pygrub by running directly - in 
your case try
/usr/bin/pygrub /dev/VolGroup02/LogVol12
as root - it should give you a choice of kernels and return the details 
for the one you pick.
