 # Nested virtualization on a template virtual machine in Azure Lab Services
 
-Azure Lab Services enables you to set up a [template virtual machine](./classroom-labs-concepts.md#template-virtual-machine) in a lab, which serves as a base image for the VMs of your students. Teaching a networking, security or IT class can require an environment with multiple VMs. The VMs also need to communicate with each other.

-Nested virtualization enables you to create a multi-VM environment inside a lab's template virtual machine. Publishing the template will provide each lab user with a virtual machine that has multiple VMs within it. This article explains the concepts of nested virtualization on a template VM in Azure Lab Services, and how to enable it.
