Dear Ian,

Thank you for your reply. But your advice came too late. I have already 
downgraded Ubuntu from 13.04 to 12.04.2 LTS, thinking it is a compiler 
problem.

By the way, based on your information, I have initially installed Xen 
4.4-unstable, then subsequently I replaced Xen 4.4-unstable with Xen 
4.3-unstable. Since this is the case, I should run ./configure 
--prefix=/usr/local in Xen 4.3-unstable to overwrite the installation of 
Xen 4.4-unstable. Am I right?
