I installed Glance and Compute node (KVM) with Ceph backend. I want to know about suitable image formats and the reason of selecting each ones. As my object and block storage (Ceph), Which kind of image format support?

In my experience, Ceph doesn't care what image format you store. But now I read "You must use only raw image formats with the Ceph RBD back end" (config guide).

Formats supported by KVM: http://docs.openstack.org/newton/conf....
