Instantiate multiple persistent virtual machines

Community Support

Hello Guys,

Is there a way to instantiate multiple persistent virtual machines using a single template?, If not, then is there a feature request already submitted, Because I would like to submit a feature request if this feature is not already submitted.

Regards

Yes, this should be covered by the ‘OneFlow’ service definition module.

http://docs.opennebula.org/4.14/advanced_administration/application_flow_and_auto-scaling/appflow_configure.html

(I do not use OneFlow myself; I just observed that it would be suitable for your use)

Cheers,
Gavin.

Hi,

There was a feature request to “instantiate to persistent”, but it was closed in favor of the onevm save functionality:
http://docs.opennebula.org/4.14/user/virtual_resource_management/vm_guide_2.html#cloning-a-vm

Hi Carlos,

Sorry for replying so late, I was looking for deploying multiple persistent VM using one template in clouduser view, But it seems that this feature is not available.

Is this in the roadmap or may be I can request for this feature.

ONE already have all the work-flow like, clone, set to persistent, may we just need to bring this altogether and add a option in template “Deploy as persistent” and this will deploy multiple persistent VMs from a non-persistent disks.

Some of our workload require persistent disks while deploying VMs and deploying them in a bulk is really a tedious and time consuming job.

This will reduce manual work for oneadmin user to create a persistent template or disk and assign it to the clouduser again and again :smile:

Hi, i’d like this feature too… It’s the only reason why i’m not using opennebula yet…
What i need is basically create persistent template ( let’s say 10gb harddisk and 1gb ram with some software already configured ) then being able to istantiate persistent vms with custom hd size, ram and CPU…

Hi

We’ll take a look to implement this feature, it is very demanded indeed…
We are revisiting the save_as template and probably we can take care of
both.

Cheers

Great news!
Do you think it will be in a point release or a major one?

Thank you very much

This will probably hit the 5.0 release.

Sorry for necroposting, but is this feature implemented?
Because i still don’t know how to instantiate many VMs with persistent image cloned from reference image.
