1Welcome, friend reader, to lguest.
   3Lguest is an adventure, with you, the reader, as Hero.  I can't think of many
   45000-line projects which offer both such capability and glimpses of future
   5potential; it is an exciting time to be delving into the source!
   7But be warned; this is an arduous journey of several hours or more!  And as we
   8know, all true Heroes are driven by a Noble Goal.  Thus I offer a Beer (or
   9equivalent) to anyone I meet who has completed this documentation.
  11So get comfortable and keep your wits about you (both quick and humorous).
  12Along your way to the Noble Goal, you will also gain masterly insight into
  13lguest, and hypervisors and x86 virtualization in general.
  15Our Quest is in seven parts: (best read with C highlighting turned on)
  17I) Preparation
  18        - In which our potential hero is flown quickly over the landscape for a
  19          taste of its scope.  Suitable for the armchair coders and other such
  20          persons of faint constitution.
  22II) Guest
  23        - Where we encounter the first tantalising wisps of code, and come to
  24          understand the details of the life of a Guest kernel.
  26III) Drivers
  27        - Whereby the Guest finds its voice and become useful, and our
  28          understanding of the Guest is completed.
  30IV) Launcher
  31        - Where we trace back to the creation of the Guest, and thus begin our
  32          understanding of the Host.
  34V) Host
  35        - Where we master the Host code, through a long and tortuous journey.
  36          Indeed, it is here that our hero is tested in the Bit of Despair.
  38VI) Switcher
  39        - Where our understanding of the intertwined nature of Guests and Hosts
  40          is completed.
  42VII) Mastery
  43        - Where our fully fledged hero grapples with the Great Question:
  44          "What next?"
  46make Preparation!
