          Select this option, if you want to share the text segment of the
          Linux kernel between different VM guests. This reduces memory
          usage with lots of guests but greatly increases kernel size.
+         Also if a kernel was IPL'ed from a shared segment the kexec system

          You should only select this option if you know what you are
          doing and want to exploit this feature.
