Virtual disks - Location and shared type

[enkidu]

Hello,
Virtual Disk location can be quite important for VM provisioning, especially for VMs with multiple virtual disks. Typically OS and data are separated, with OS disk using location 0. Ideally it would be per-VM autoincrementing field being property of VirtualDisk itself, with contrains (min/max) declared on cluster level. Of course, naming convention can be used as a workaround here. Haven't really seen multiple controllers myself, but I can imagine there is some deployment out there using such an approach.

Another issue is shared virtual disk type - useful for nested clustering. For example, clustered fileserver or SQL server running under clustered hypervisor will have shared disks (data and witness). Current model limits disk ownership to a single VM.
