#add_delta_disk_layer_on_all_disks ⇒ Object

Add a layer of delta disks (redo logs) in front of every disk on the VM. This is similar to taking a snapshot and makes the VM a valid target for creating a linked clone.

Background: The API for linked clones is quite strange. We can’t create a linked straight from any VM. The disks of the VM for which we can create a linked clone need to be read-only and thus VC demands that the VM we are cloning from uses delta-disks. Only then it will allow us to share the base disk.
