How can you say the guest is badly setup ? I used virt-manager to install a fresh centos5 pv domain using file based image, gave it the installation CD to use. It installed perfectly fine and was working also fine. Unless virt-manager itself creates a badly behaved guest ?

And then once i remove centos5 xen packages, virt-manager, compile xen 3.1.1, the image stopped booting. Once i add those lines, it starts to work again.

Switching from a compiled configuration for *one* version of Xen, namely 3.0.x for CentOS 5, to another verson of Xen, namely 3.1.1, is sort of asking for backwards compatibility trouble.

I'm afraid such problems are likely to recur with hand-implemented Xen migrations to more recent releases, at least until RedHat has decided to update to it. And that's unlikely for RHEL 5: the stability of such OS version sis a big selling point for RedHat.
