+	  PVH is an experimental guest mode that is a cross between
+	  full PV and HVM. The hypervisor ABI for PVH guests is not
+	  yet stable and this kernel may not boot in PVH mode on later
+	  Xen hypervisors.
+
+	  Do not enable this option unless you are a developer working
+	  on PVH guest support.
