This is a known bug in the /etc/init.d/xendomains script - the parseln
function uses a hardcoded value (something like 17 chars) instead of
using spaces as separators, to get the hostname from screenscraping
xm.

The problem is fixed in Xen unstable upstream(with a pervetedly long
patch)  and in newer Debian(unstable) xen packages, as well as in the
xen 3.1 packages from debianbase (with a simple and very short patch).
