A VM deployed by cloning another VM creates an exact copy of the original VM. Cloning is the fastest method to deploy a new VM if an existing VM has the same features and applications you need for the new installation. When using the Clone option, the new VM will have exactly the same configuration as the source one (for instance, the same IP address will be configured within the guest OS or hostname). A new VM on the vSphere level will, of course, have a different UUID or MAC address.

This procedure allows you to save time during deployment because you simply need to clone and configure a few parameters.
To deploy a new VM by cloning an existing one, follow these steps:

1. From the vSphere Client, log in to the vCenter Server and access the inventory view. Right-click the VM to clone and select Clone | Clone to Virtual Machine to create a new VM.
2. Enter the name of the virtual machine and select the location in which to deploy the VM, then click Next.
3. Select a computer resource to allow the VM to access the resources of the selected object. If the compatibility checks succeed, click Next to continue.
4. Select the storage in which to store the configuration and disk files. Make sure you have sufficient space in the selected datastore. Specify the virtual disk format and click Next.

5. In Select clone options, you can customize the guest OS to prevent conflicts (a duplicate computer name or IP address already in use) and automatically power on the VM once it is deployed. Click Next.
6. In the Summary window, click Finish to begin the cloning process of the selected VM:
