Thanks for the feedback. I will be looking forward to those patches in Liberty.
In the meanwhile, it appears my best option would be to manually sparsify the
Glance images using qemu-img convert.

Several patches aim to solve that by using RBD snapshots instead of QEMU
snapshots.
Unfortunately I doubt we will have something ready for OpenStack Juno.
Hopefully Liberty will be the release that fixes that.
Having RAW images is not that bad since booting from that snapshot will do a
clone.
So
Hello all.
The current behavior of snapshotting instances RBD-backed in OpenStack involves
uploading the snapshot into Glance.
The resulting Glance image is fully allocated, causing an explosion of
originally sparse RAW images. Is there a way to preserve the sparseness? Else I
can use qemu-img
