CLOUDSTACK-5172. Detaching VM volume is not allowed if there are VM snapshots
because any changes to the disk layout will break the semantics of VM-based
snapshot
> Removing disks from VMWare VMs with snapshots causes problems

> Components: Snapshot, VMware

>
> We currently don’t allow volumes to be attached to VMs with snapshots and
> allowing volumes to be detached causes quite a bug:
> 1) Attach a data disk to a VM
> 2) Snapshot the VM
> 3) Detach the data disk
> 4) Attempt to restore the VM from the snapshot — FAILS since the data disk is
> no longer there, although it is expected to be
> 5) Attempt to re-attach the volume to the VM — FAILS since you cannot attach
> volumes to VMs with snapshots
> 6) Attempt to delete the VM snapshot — FAILS since the data disk is no longer
> there, although it is expected to be
> I have verified the above steps on VMWare, however Xen does not appear to
> fail on step 4, presumably because VMWare handles snapshots quite differently
> than Xen.
> After discussion on the dev list, it sounds like the proper course of action
> would be to prohibit disks from being detached from VMWare VMs with snapshots.
