Creating a Volume from a Volume (Clone)

You can create an image using Cinder backup, and from that image create another volume, and boot your instance from that volume. You can take a snapshot of your original VM and create a second instance booting up from that snapshot. The hostname can be changed using cloud-init (or manually after the first boot).

The following screenshot illustrates how to create a volume from a volume (clone) in Lightbits.
