ok, I understand now ;)

Indeed, currently, a template is a vm with a base-xxx disk.

Maybe can we improve that ? 


Note: my patches can also clone a vm without need to be a template, and without disk.


Do you want to clone this template to create a new vm without disk ?

there is no drive at all it's the name of the VM. 

name: base-template-test 

but it seems i can't create a template without a drive ;-) I just wanted 
to have a template with settings for VMs. Like predefined configuration 
without a disk.
