Comment 34 for bug 1202266

This one is since folsom, when live-migrate landed, totally my bad:
https://blueprints.launchpad.net/nova/+spec/xenapi-live-migration

The backport should be more straight forward for this one, although there has been quite a lot of rework around live-migrate recently, it shouldn't fundamentally change things.

Sorry for the delay, seem to have lost the updates on this in the regular email soup.
