[one-users] Instantiate to Persistent

Tue Feb 19 11:44:19 PST 2013

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.

Regards,
Ricardo

Hi
Yes, I did not really get the use case here.
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 ....
Cheers

Ruben

Hi Ruben,
I guess I was still not able to express the use case correctly.
- I want to have a template, registered within onetemplate, that generates machines with persistent disks, cloned from a master disk

- The only action I want to do to create the virtual machines is to run onetemplate instantiate- 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 want OpenNebula to clone the disk to the datastore and set it as persistent instead.

Is it possible?

OK, I think you can use onevm saveas for this:

Hi,

I will try to explain what I am trying to do:

- Say I have a template that uses image id 10, that is not persistent.
- Every time a user creates a new image with this template, I want the image id 10 to be cloned into a new persistent image, that is then allocated to the instance

Currently, when I instantiate a template with a non-persistent image, the image is cloned to a volatile disk on system DS.
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.

Thanks,
Ricardo

Hi Ricardo,

We are missing something here,  I think that a persistent image is what you are looking for [1]. If not could you elaborate a bit what are you missing?

Cheers

Hi there,

I'm trying to make all my virtual machines persistent.
So, I would like disks for vms instantiated from templates to be created as persistent clones, instead of volatile disks on system DS.

Is there a way to do it?

Thanks,
Ricardo
