15 The "Nested VMX" feature adds this missing capability - of running guest
16 hypervisors (which use VMX) with their own nested guests. It does so by

32 In nested virtualization, we have three levels: The host (KVM), which we call
33 L0, the guest hypervisor, which we call L1, and its nested guest, which we
