My only concern about this patchset is how the "name" attribute is overloaded (historically) to include both the RBD pool and image name. Now if the RBD namespace is separated out to its own optional attribute, it requires constructing an invalid "<pool>/<image-name>" name attribute.  Can the pool be separated out to its own attribute as well  (i.e. <source ... image="image1" pool="rbd" namespace="ns1"...>) and keep a deprecated backwards

compatible "name='pool/image'" attribute that doesn't support namespaces? The QAPI already has the pool and image as separate attributes.
