+         Paravirtualization is a way of running multiple instances of
+         Linux on the same machine, under a hypervisor.  This option
+         changes the kernel so it can modify itself when it is run
+         under a hypervisor, improving performance significantly.
+         However, when run without a hypervisor the kernel is
+         theoretically slower.  If in doubt, say N.
