Did you mistype your comment or misread mine? Raw does NOT work for snapshots.
snapshots only work for qcow2. Implementing snapshotting with raw would be
possible. Logic just needs to be added to skip the internal snapshot step and
just use the entire file when uploading to glance. This
Since we're talking snapshots, quick doc-related snapshot questions:
- Are snapshots only supported on qemu/kvm, or do they work with other
hypervisors as well? (Does Xen support qcow2 images?)
- Does OpenStack do anything with snapshots other than using them to generate
new images? I was a

What changes would be needed to make qcow2 files work as snapshots?
Some type of image dependency management in glance (and failure cases) and
the corresponding dependency fetching in nova (and failure cases)?
Might be something pretty useful to have, instead of forcing raw
So the ability to create a snapshot, rollback to a snapshot and to create a
new snapshot that references a snapshot as its base are strong
candidates for abilities to design for volume drivers. Any device that did
not support this capability would simply state so. Snapshotting would

Would this also be applicable to the ephemeral instance storage?
An ephemeral instance is essentially a non-persistent clone of a snapshot image.

Ok, but forcing a new block storage project to have this feature, is that the
right way?
Maybe it will, just wondering.
Glance seems to be the registry of images, so a natural progression is that it
can maintain the image dependencies?
This would allow the qcow2 image to pull the needed
Hi all
we plan to use openstack on our production,
we are not sure which disk type will be the better choice
I did a little test on qcow2 and it's performance looks good when I use
cache=writeback
can some one give us some advice, or some article,
cause for such common topic must be discussed
Hi,qcow2 for all the advantages it has : resize, compress, snapshopt, convert, backing files :-)
