[one-users] Simplified VM creation?

[Shek Mohd Fahmi Abdul Latip]

Hi Pentium100,

What I can suggest to simplify VM deployment by developing a so called "golden image" and "golden template" in advanced. From there, you just make use of context and cloning features to ease your deployment.

Just my 20cent.

Best regards,

Subject: [one-users] Simplified VM creation?

Hello,
While trying out OpenNebula, I noticed that the VM creation process is quite inconvenient if I want different VMs (as opposed to scaleout situation).
1. Create the image (upload a new one or copy some other image), set it as persistent (I don't want the VM to disappear if I shut it down).
2. Create a template that uses the image.
3. Finally create a VM from the template. There will only be one VM using that template (because I don't really need two identical VMs).
To create 10 virtual servers (all the same "hardware" but different images) I need to repeat steps 1-3 ten times.

It would be nice, if there was a way to simplify this. I can think of 3 ways to do it:
1. Skip the creation of a template. Create an image then create a VM based on that image.
2. Do not define an image while creating a template. Assign the image when creating the VM.
3. Have some "template" image that gets copied when a VM is created. The copy should be persistent.
Is there a way to do it? Non-persistent images behave almost like option 3, but accidentally shutting down a VM would mean data loss.

We have quite a few VMs, but they all are used as real servers would be - all have different data (no scaleout) and none can be deleted easily.
