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: https://bugzilla.redhat.com/show_bug.cgi?id=746602 (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 yet. Has anyone found a way to install F16 as a domU guest on Centos 5.7? On 20 December 2011 00:33, Scot P.
