Subject: virt-xml: refactor the handling of --define and --update options
From: Pavel Hrdina phrdina@redhat.com Thu Jul 2 14:09:46 2015 +0200
Date: Tue Jul 7 10:42:32 2015 -0400:
Git: 76bad650dea9f83305f4a77bf83dee34d79e5308

The code was wrong in many ways.  The main issue was, that for live
updates we were using config XML instead of live XML.

This patch fixes the --update and --define options to work properly as
described in man page.

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1192875
