[Pkg-xen-devel] Bug#624788: Python version issue: "ImportError: No module named lxml"

[Moonwalker]

Package: xen-utils-4.0
Version: 4.0.1-2

Right after another Wheezy distribution update I've faced the following issue with "xm".
=====
host:~# xm new /etc/xen/domains/test.cfg
Unexpected error: <type 'exceptions.ImportError'>

Please report to xen-devel at lists.xensource.com
Traceback (most recent call last):

=====

The cause is that the current version (2.3-0.1+b2) of python-lxml package in Debian Wheezy available only for Python 2.6 and 2.7. You can safely change python2.5 dependency to python2.6. Also you need to modify /usr/lib/xen-4.0/bin/xm shebang to "#!/usr/bin/python2.6". Works flawlessly.
