Comment 4 for bug 1077817

Well,we have to admit that there exist some scenarios which require several ceph clusters as backends-although Ceph is power enough to properly combine 2 clusters into 1 by clush rules ,but it require much more effort than just starting several cinder-volume instance and config proper monitor addresses for them.

I am not sure if sheepdog face the same situation since sheepdog need gateway address for data accessing.As a framework,Nova and Cinder should work together to support passing more informations from cinder configuration to libvirt.
