[openstack-dev] [glance] Proposal for a StorPool image backend driver

Hi,

Hm, looks like I was a bit confused as to the procedure of submitting
a blueprint and a spec for a new Glance image backend driver - and
yeah, the actual text of the "Reviewers" section of the spec should
have made me at least ask on the list...  So here I am, asking, and
sorry for the prematurely filed blueprint.

So, what do you peope think about a new image backend driver, using
snapshots in a StorPool distributed storage cluster?  The idea is that
since we already have an approved Cinder blueprint for volumes and we
are on the way of getting an approved Nova blueprint for attaching
StorPool-backed Cinder volumes, it might be nice to also have Glance
support, so that creating volumes from images and creating images from
volumes would be a breeze.  This will also help with another Nova spec
that I'll file today - using StorPool volumes instead of local files
for the Nova VM images; then cloning a Glance image to a Nova VM image
will also be a breeze.

Here's some more information:

- my prematurely filed blueprint:

- my prematurely filed spec: https://review.openstack.org/#/c/137360/

- the Cinder volume support blueprint:
https://blueprints.launchpad.net/cinder/+spec/storpool-block-driver

- the Nova "attach StorPool-backed Cinder volumes" blueprint:
https://blueprints.launchpad.net/nova/+spec/libvirt-storpool-volume-attach

Please feel free to ask for any additional information and
clarifications, and once again, sorry for filing a blueprint against
the rules!

G'luck,
Peter
