[one-users] Simplified VM creation?

[Pentium100]

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.
