As specified in Intel's SDM, do not allow the L1 hypervisor to launch an L2 guest with the VM-execution controls for "unrestricted guest" or "mode-based execute control for EPT" set and the VM-execution control for "enable EPT" clear. Note that the VM-execution control for "mode-based execute control for EPT" is not yet virtualized by kvm.
