Sorry for the top post but I think it's appropriate here. The message
below was posted 20th of December last year with no response. I've now
hit the same problem.

I have CentOS 5.7 and and trying to install an F16 domU PV guest. It
seems that pygrub is failing to read the grub2 setup.

It also seems that there is a fix for this in xen-3.0.3-135.el according to:


(pygrub cannot start F16 PV guests (GPT partition) under Xen 4.1.1)

However, centos only has xen-3.0.3-132.el5_7.2 and so does not have
the pygrub fixes and I'm not even sure RH has relased xen-3.0.3-135.el

Has anyone found a way to install F16 as a domU guest on Centos 5.7?
