Comment 3 for bug 1009974

Added this as a doc bug, here's a copy-paste from an email from Florian:

Apologies for the noise. I had mistakenly believed that since the list
of --live_migration_flags contained spaces, it was OK to quote the
--live_migration_* options. Evidently it's not, as removing the double
quotes made the problem go away. My guests now do migrate.

Anne/Thierry: I've thus far been unable to find any documentation that
says "don't use double quotes in nova.conf". In fact,
http://docs.openstack.org/trunk/openstack-compute/admin/content/compute-options-reference.html
uses them in several places, including the --live_migration* flags. That
quotes can break things appears to be a known issue as per
https://bugs.launchpad.net/nova/+bug/987473. Is this something that we
should mention in the documentation, or is this unexpected parser
behavior that needs to get fixed?
