It appears that the RBD driver in Cinder only checks that the image is accessible, and if it is, assumes it is cloneable, regardless of its format. I think it would be more useful if the driver also confirmed the image format, and reverted to straight copy instead of copy-on-write if the format is anything else but raw.
