On a related note, some weeks ago, I captured some context and analysis
(including some debugging done by Dan Berrange and Eric Blake on public
IRC channel mid-last year) for the above bug, since the actual bug has
too many comments:
https://kashyapc.fedorapeople.org/virt/openstack/nova-live-snapshot-bug-1334398-context-and-analysis.txt
The cause of it is almost narrowed down here by Dan in this comment
