Hi Ruben, I'm currently using the API. I know I can do it as you said, but it is not a single operation. It requires to track state, wait for images to be cloned, etc. It would be nice to be able to instantiate persistent images in the same way as we instantiate regular non-persistent. So, if the template has a base image and type=PERSISTENT, then OpenNebula would clone the disk and add it to the VM automatically. As far as I can see, this is not supported currently.

So from your email: "OpenNebula would clone the "source" disk, add it to the machine template and instantiate the machine when I run onetemplate instantiate. So far, I can only do this with non-persistent disks, where OpenNebula clones the source disk into a volatile disk inside system ds." I think that we are unsing the same word for different things. OpenNebula will clone any non-persistent images, (that is the way to keep the image untouched). But you need to clone a persistent image, right? Why not changing the image to non-persistent then?. If you need to clone but preserve the changes you can save_as the image, or maybe stop / resume the VM. Or, do you want to implement an special semantics for the clone operation? Or maybe you want to take a template using an image, copy that image make it persistent and create a VM using the original VM but with the copied image? Something like (assuming img and tmpl are the image and template you are interested in): #clone imageoneimage clone img new_img #clone the the templateonetemplate clone tmpl new_tmpl #change base disk in the new_tmpl, hakish I know EDITOR="sed -i 's/IMAGE=\"img\"/IMAGE=\"new_img\"/g'" onetemplate update new_tmpl #instantiantiage the new tmplonetemplate instantiate new_tmpl Hope it helps ....

So far, I can only do this with non-persistent disks, where OpenNebula clones the source disk into a volatile disk inside system ds.I want OpenNebula to clone the disk to the datastore and set it as persistent instead. Is it possible?

To create a persistent instance, I need to manually clone the image, then make the clone persistent, then create a new template that points to it.

If not could you elaborate a bit what are you missing?
