Apply a Customization Specification to a Virtual
You can add guest OS specification to an existing virtual machine. When you customize a guest operating system, you can prevent conflicts that might result if you deploy virtual machines with identical settings, such as duplicate computer names. You can change the computer name, network settings, and license settings.
When you clone an existing virtual machine, or deploy a virtual machine from a VM template in a folder, you can customize the guest operating system of the resulting virtual machine during the clone or the deployment tasks.
When you deploy a virtual machine from a template in a content library, you can customize the guest operating system only after the deployment task is complete.
