After you create a template, you can clone it to a template. Templates are master copies of virtual machines that let you create ready-for-use virtual machines. You can make changes to the template, such as installing additional software in the guest operating system, while preserving the state of the original template.

Verify that you have the following privileges:

Virtual machine.Provisioning.Clone template on the source template.

Virtual machine .Inventory.Create from existing on the folder where the template is created.

Datastore.Allocate space on all datastores where the template is created.


To make changes to a template and preserve the state of the original template, you clone the template to a template.


If you started the New Virtual Machine wizard from an inventory object other than a template, you select a template to clone.


When you deploy a template to the vCenter Server inventory, you provide a unique name for it. The unique name distinguishes it from existing templates in the virtual machine folder or datacenter. The name can contain up to 80 characters. You can select a datacenter or folder location for the template, depending on your organizational needs.


When you deploy a virtual machine template, select a host or cluster resource for the template. The template must be registered with an ESXi host. The host handles all requests for the template and must be running when you create a virtual machine from the template.


Each virtual machine or virtual machine template requires a folder or directory for its virtual disks and files. When you create a virtual machine or template to deploy to the vCenter Server inventory, select a datastore or datastore cluster for the virtual machine's configuration and other files and all of the virtual disks. Each datastore can have a different size, speed, availability, and other properties.


Before you deploy the template, you can review the template settings.
