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.
