Abstract
A system includes a processor providing hardware virtualization, and a memory to store a first virtual machine data structure corresponding to a first nested virtualization level and a second virtual machine data structure corresponding to a second nested virtualization level. The virtual machine data structures assist management of the hardware virtualization provided by the processor. The system includes a first nested virtual machine located within the first nested virtualization level and a second nested virtual machine located within the second nested virtualization level. The system includes hypervisors to manage the nested virtual machines using the virtual machine data structures. A root hypervisor is to manage the first nested virtual machine using the first virtual machine data structure. A first nested virtualization level hypervisor is to run within the first nested virtual machine and is to manage the second nested virtual machine using the second virtual machine data structure.
