+Special Requirements for Virtual Deployments
+--------------------------------------------
+
+In scenarios where advanced performance options or features are used, such
+as using huge pages with nova instances, DPDK, or iommu; it is required to
+enabled nested KVM support. This allows hardware extensions to be passed to
+the overcloud VMs, which will allow the overcloud compute nodes to bring up
+KVM guest nova instances, rather than QEMU. This also provides a great
+performance increase even in non-required scenarios and is recommended to be
+enabled.
+
+During deployment the Apex installer will detect if nested KVM is enabled,
+and if not, it will attempt to enable it; while printing a warning message
+if it cannot. Check to make sure before deployment that Nested
+Virtualization is enabled in BIOS, and that the output of ``cat
+/sys/module/kvm_intel/parameters/nested`` returns "Y". Also verify using
+``lsmod`` that the kvm_intel module is loaded for x86_64 machines, and
+kvm_amd is loaded for AMD64 machines.
