After the cloning process is completed you will have a clone of the Base VM you have configured. You will use this for creating the VM Template. The original VM (i.e. the VM clone) is destroyed after a VM Template is created.
Later on, you might need to modify your VM template. In that case you will use the base VM available that has thankfully remained intact.
...
71) Once the VM clone is created, right-click on it and click on Properties.
