+          This is a very simple module which allows you to run
+          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.
