Blank Virtual hard disk templates on demand without requiring a library object
When creating a VM template, if you want to add a data disk, you have to precreate the datadisk and load it into the library. If you want it Fixed, you have to take the time to precreate a Fixed VHDX and import it. Also if you want to add multiple data disks you must have unique entries in the library, they cannot be reused inside the same vm template. I propose allowing blank virtual hard disk templates of Fixed type of a specified size to be described in the template, and have scvmm create the disk on demand during provisioning as described without needed the disk in the library to copy.

Service templates group VMs together to provide an app. They contain information about a service, including the VMs that are deployed as part of the service, the applications installed on VMs, and the network settings that should be used.
