xml.etree.ElementTree.ParseError not supported in Python 2.6

[Lorin Hochstein]

Unit tests fail in Python 2.6.5. Example:

Traceback (most recent call last):
 File "nova/tests/test_virt_drivers.py", line 437, in setUp
   import fakelibvirt
 File "nova/tests/fakelibvirt.py", line 18, in <module>
   from xml.etree.ElementTree import ParseError
ImportError: cannot import name ParseError

It looks like some code is using some ElementTree functionality that isn't in Python 2.6.x. Here's Python 2.6.6 on RHEL 6.1:

$ python

    Make fakelibvirt python2.6 compatible

    Fix bug #893757. In Python 2.6 xml.etree.ElementTree.fromstring
    raises xml.parsers.expat.ExpatError instead of
    xml.etree.ElementTree.ParseError when faced with invalid xml.
    Adjust accordingly.
