These sorts of errors usually mean your toolstack and hypervisor are

One common way this can happen at the moment is that Xen recently
switched to installing in /usr/local by default instead of /usr
(mentioned in http://wiki.xen.org/wiki/Xen_4.3_Release_Notes). If you
have previously installed Xen into /usr then you might pickup the
old /usr/sbin/xl instead of the new /usr/local/sbin/xl.

The solution is to either clean out any remnants of the old installation
from /usr (e.g. "make uninstall" in the old source tree, or by hand) or
to install the newer version with "./configure --prefix=/usr".


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?

Yours sincerely,
Singapore Citizen Mr. Teo En Ming (Zhang Enming)
