Here is one option that you could use. Create a volume instead of an image (or create the volume from the image), snapshot the volume. If you pass the volume snapshot in as a secondary drive in block_device_mapping on boot, then you will get a volume copy of the image. If it is delete_on_terminate=True then the volume will be deleted when you terminate the vm.
