Which statement about virtual machine templates is incorrect?

The statement about virtual machine templates that is incorrect involves the notion that templates can be utilized across different virtualization platforms. While some virtualization technologies provide compatibility or options for converting templates between different systems, generally, virtual machine templates are designed to work within the specific context of the virtualization platform for which they were created. This means that a template developed in one hypervisor environment may not be directly usable in another without a conversion process or intermediary steps.

On the other hand, some aspects of virtual machine templates, such as cloning, custom parameters, and template existence post-cloning, adhere to standard functionality. For instance, cloning a virtual machine to create a template does not erase the original virtual machine, and custom parameters can indeed be set to tailor the deployment of multiple instances efficiently. Furthermore, when a template is converted into a virtual machine, the original template typically remains available until deletion is manually executed, reinforcing that templates are routinely maintained and utilized within their respective environments.
