Sorry, I thought this email went to the upstream virt-manager list, hence I
was focusing on that :)

RHEL5 xen is an old frankenstein monster at this point as well, so could be a
xen issue that just hasn't been backported.

CCing fedora xen list as well, maybe they have ideas.

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=d513814db6af2b...
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.

It might be this one:

https://bugzilla.redhat.com/show_bug.cgi?id=1039171

CC-ing Jim on it

It was a bit hard to find it - but basically you had to use --network
parameter and if you used a bridge - then it had to be called 'xenbr0'.
