To prevent conflicts that can occur if you deploy virtual machines with identical settings, such as duplicate computer names, you can apply a customization specification to an existing virtual machine.
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.
Prerequisites
- Verify the guest operating system is installed.
- Verify that VMware Tools is installed and running.
- Power off the virtual machine.
