This is a great news.
We are finishing the development of the new OpenNebula catalog
component. This component will interact with external repositories in
order to create new images in the OpenNebula repository. You can
follow up its development in the following link [1]. So as we talked
in the last IRC session, it would be nice to have a CDMI driver for
this component.

As Ignacio said, do not hesitate to send us any questions that you
have about this integration or any suggestions about the component.

BTW, there was a typo in the previous mail in my contact information:
Daniel (dmolina at opennebula.org)
instead of
Daniel (dmolona at opennebula.org)
