US Patent 10467033 Enabling efficient nested virtualization

Embodiments of the invention enable dynamic level boosting of operations across virtualization layers to enable efficient nested virtualization. Embodiments of the invention execute a first virtual machine monitor (VMM) to virtualize system hardware. A nested virtualization environment is created by executing a plurality of upper level VMMs via virtual machines (VMs). These upper level VMMs are used to execute an upper level virtualization layer including an operating system (OS).
