my view is the use case of shared disk defined at template level is 
nice, but can be done at a later phase. the higher priority would be to 
actually support a shared disk, even if user needs to attach it to the 
VMs they instantiated from the template.
so we need to remember the template use case, and not do things making 
it more complex later, but can also do some validations preventing it if 
it makes things more complex.
