This new RBD format supports snapshotting and cloning. By having

Older versions of libvirt can work with this new RBD format as long
as librbd supports format 2, something that all recent versions of
librbd do.
Did somebody get a look at this patch yet? It's a fairly simple one, but
would be great for the Ceph project!
So I'm thinking we might want to do something similar with the compat
attribute added for qcow2 for the versioning that way things are
explicitly stated rather than implicitly switching versions on us.
Problem is that we are linking to a library here on compile time and not
executing a binary to create the image.
The Ceph project is still very new, almost nobody is actually using the
format 1 images anymore. I wouldn't recommend anybody creating format 1
images now.
They still work just fine, but we don't want to encourage people to keep
using them.
