I think you could use a live disk snapshot [1] for that. OpenNebula will
create a new Image in the same datastore as the original Image, and then
you can clone that new img to a different DS [2] (in the same zone).

Moving images to a different zone is not supported. To do that, you can
take the image file from the DS, the file's path is stored in the SOURCE
attribute shown in 'oneimage show <id>'. This will be straight forward for
file-based datastores, not so much for other type of drivers. Then register
a new image in the new zone as usual.

Hope it helps
