[Qemu-devel] [PULL 5/5] migration: fix analyze-migration.py script

[Juan Quintela <quintela@redhat.com>]

From: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>

Commit 61964 "Add configuration section" broke the analyze-migration.py script
which terminates due to the unrecognised section. Fix the script by parsing
the contents of the configuration section directly into a new
ConfigurationSection object (although nothing is done with it yet).
