+	  multiple instances of the same Linux kernel, using the
+	  "lguest" command found in the Documentation/lguest directory.
+	  Note that "lguest" is pronounced to rhyme with "fell quest",
+	  not "rustyvisor".  See Documentation/lguest/lguest.txt.

+	  The guest needs code built-in, even if the host has lguest
+	  support as a module.  The drivers are tiny, so we build them
+	  in too.
