QEMU Assisted Snapshots

Registered by Eric Harney on 2013-05-07

QEMU-assisted snapshotting

Enable snapshotting of volumes on backends such as GlusterFS by storing data as QCOW2 files on these volumes. With Nova support, this can also enable quiescing via the QEMU guest agent.

Whiteboard

There is a blueprint for the Cinder part of this at:
https://blueprints.launchpad.net/cinder/+spec/qemu-assisted-snapshots

I think this needs some more detail. It would be good to lay out a more detailed description and proposed design on a linked wiki page. --russellb
