This new RBD format supports snapshotting and cloning. By having libvirt create images in format 2 end-users of the created images can benefit of the new RBD format.
What's the compatibility like here. If one node creates a v2 image, can a host which only knows v1 still use that v2 image for booting guests ?
Only very old clients won't be able to open v2 images when they only support v1. Ceph is however a fast moving project where almost all users are on the most recent versions of Ceph due to new features and bug fixes. Wido
