Hi Matt,

Sorry I couldn't reply earlier - was away.
I'm worrying about ScaleIO ephemeral storage backend 
(https://blueprints.launchpad.net/nova/+spec/scaleio-ephemeral-storage-backend) 
which is not in this list but various clients are very interested in 
having it working along with or instead of Ceph. Especially I'm worrying 
in view of the global libvirt storage pools refactoring which looks like 
a quite global effort to me judging by a number of preliminary reviews. 
It seems to me that we wouldn't be able to squeeze ScaleIO additions 
after this refactoring.
What can be done about it?
We could've contribute our initial changes to current code (which would 
potentially allow easy backporting to previous versions as a benefit 
afterwards) and promise to update our parts along with the refactoring 
reviews or something like this.

Best regards,
   Alex Levine
