Abstract

Approaches for performing nested virtualization using a hypervisor which does not support nested virtualization. A first hypervisor is loaded upon booting a computing device. The first hypervisor instantiates a first virtual machine, exposes an emulated hardware virtualization support interface to the first virtual machine, and executes a second hypervisor, which does not support nested virtualization, within the first virtual machine. The first hypervisor provides nested virtualization support to the second hypervisor to allow the second hypervisor to execute a third hypervisor within a second virtual machine by the first hypervisor abstracting hardware virtualization support to the third hypervisor.
