Not yet? Imagine we extend the "Create VM" function to be available to 
the User,
rather than being restricted to the Admin?
Our target audience is new to virtualization and host administration.
He likely doesn't know what SCSI is; its even less likely that he cares.
How would he know what volume to choose? Could choosing the wrong one do 
harm?
He has access to create VMs from more than one template.
One asks him for volumes, one doesn't? Why?

We want VM creation to be a consistent experience, with no opportunity 
for failure or corruption.
