sourceMachineImageId property
The unique ID of the machine image used to create this disk. This value identifies the exact machine image that was used to create this persistent disk.
For example, if you created the persistent disk from a machine image that was later deleted and recreated under the same name, the source machine image ID would identify the exact version of the machine image that was used.
Output only.
