Hi Ruben, Thank you very much for the updates. Looking forward to see some of this features in the upcoming version.

I totally agree that we need to simplify the provision process even more. About feature 1. We have two issues: [1] Clone a running VM. http://dev.opennebula.org/issues/2637 [2] Clone a template . http://dev.opennebula.org/issues/2051 Last one includes images (pretty much the procedure outlined by Anandharaj under "New VM request") and I think this will cover exactly your request. About feature 2. We want to add the ability to update any part of a template for VM, most of it can be done if the VM is running (eg. attach a new disk or nic). Others like memory can be resized when the VM is powered off. You would not need to update and recreate the template. [3] http://dev.opennebula.org/issues/2065 So, I believe we can implement the workflow described by Anandharaj with these features (and exposing it through Cloud View)... Thanks for your feedback!

I start think about a dedicated web service to handle that, but a shorter (quicker) way to achieve deployments would be nice ! I will follow this thread for feebacks too Best regards, NB Le 02/10/2014 06:07, Anandharaj Subramaniam a écrit : Hi All, Just need some clarification and would like to get you guys feedback on managing VMs using OpenNebula in your environment. Our current practice as below (using OpenNebula 4.2): 1. New VM request - Clone existing image (master image) to a new image. All the images are persistent. - Clone existing template (master template) to a new template. - Update the new template – set cpu/vcpu, memory, image (point to newly created image), ip address, etc - Instantiate the template 2. Update the spec of the VM - Shutdown / delete the running VM - Update the template belongs to that particular VM – e.g set the new memory size - Instantiate the template Note: a) In our setup, every VM will have their own template as per done in #1 b) Reason being update the template & re-instantiate instead of just update the memory in VM is because of #3 below 3. Repair the VM - In some cases the VM’s filesystem will have some errors (eg: due to force shutdown / nfs issues) therefore require to run fsck using live CD. - Image type CDROM cannot be attached thru VM list page (click on the VM -> storage tab) - Update the VM’s template – add disk and choose the ISO image, choose boot = cdrom - Instantiate the template and fix the errors using the live CD - Shutdown / delete the running VM - Update the VM’s template – remove the ISO image and choose boot = hd - Instantiate the template From the above scenario, anything that we are doing inefficiently? Im still new to this OpenNebula so appreciate you guys feedback / suggestion Testing environment (OpenNebula 4.8) To further understand on this OpenNebula, I have setup ONE 4.8 and testing the Cloud View and see how I can improve my operation / VM administration. The way user can create VM in Cloud View is the one I need – user define the VM name, choose the template (OS), set the memory & CPU and launch it. Very simple. But unfortunately this only works with non-persistent image type. In my case, I cannot use non-persistent image because of the reason stated in #2 and #3 above. So what I think Cloud View can be improved is: - Based on config parameter (oned.conf -> ONE_DEPLOY=Persistent), when user create a VM, a template should be created and the image should be cloned as persistent image. This is kinda same behavior as “Save” VM with only different is the image persistent yes/no and template spec - Able to attach / detach CDROM Feel free to comment on this and provide some feedback. -- Regards, Anandharaj ________________________________ DISCLAIMER: This e-mail (including any attachments) is for the addressee(s) only and may be confidential, especially as regards personal data.
