Re: [Xen-devel] Problems "upgrading" 3.1 to 3.2?

Yeah, it'll be some kind of "residue" problem.  Unfortunately there's not a 
particularly clean way to uninstall Xen.

You could try removing /usr/lib/libxen* and /usr/lib/python/xen and then 
reinstalling the tools.  Does that help?

Otherwise, I'm afraid you're going to need to keep hunting down Xen-installed 
binaries until the problem goes away :-(

Cheers,
Mark
