Hi,

Today when creating a VM from template the user can choose the
provisioning method:
- It can be 'Thin' in which the engine is taking a snapshot of the
template disks (running AddVMCommand which executes
CreateSnapshotFromTemplateCommand)
- Or 'Clone' which results in cloning the template disks (executes
AddVmFromTemplateCommand which in turn executes
CreateCloneOfTemplateCommand)


Thanks, Livnat
