Daniel P. Berrange bcb3e00929 Fix XML config tests for disk/net/cpu tuning 
Due to a bug in the XML matching code, some XML formatting
problems related to disk/net/cpu tuning were not flaged as
errors. The problems were all simply ordering of the elements.
This patch also fixes some indentation problems at the same time

Fixes bug #1130146
Change-Id: Iee392ed823002b8231b33c27b487c2538b2dc8cd
