Nested virtualization is a system in which one can run virtual machines inside other virtual machines, so one can create their own virtual environments. It works in such a way that it enables a hypervisor inside a virtual machine (VM) which itself is a hypervisor.

This technology is useful in a variety of scenarios, such as:
Nested virtualization systems have various advantages over traditional on-site solutions. The following are some of the most prominent advantages:
