cat /sys/module/kvm_intel/parameters/nested
      vi /etc/modprobe.d/kvm-nested.conf

      ---> Contains

                  options kvm-intel enable_shadow_vmcs=1
                  options kvm-intel enable_apicv=1
                  options kvm-intel ept=1
      modprobe -r kvm_intel
      modprobe -a kvm_intel
      cat /sys/module/kvm_intel/parameters/nested
