- Welcome, friend reader, to lguest.
- Lguest is an adventure, with you, the reader, as Hero. I can't think of many
- 5000-line projects which offer both such capability and glimpses of future
- potential; it is an exciting time to be delving into the source!
- But be warned; this is an arduous journey of several hours or more! And as we
- know, all true Heroes are driven by a Noble Goal. Thus I offer a Beer (or
- equivalent) to anyone I meet who has completed this documentation.
- So get comfortable and keep your wits about you (both quick and humorous).
- Along your way to the Noble Goal, you will also gain masterly insight into
- lguest, and hypervisors and x86 virtualization in general.
- Our Quest is in seven parts: (best read with C highlighting turned on)
- I) Preparation
- - In which our potential hero is flown quickly over the landscape for a
- taste of its scope. Suitable for the armchair coders and other such
- persons of faint constitution.
- II) Guest
- - Where we encounter the first tantalising wisps of code, and come to
- understand the details of the life of a Guest kernel.
- III) Drivers
- - Whereby the Guest finds its voice and become useful, and our
- understanding of the Guest is completed.
- IV) Launcher
- - Where we trace back to the creation of the Guest, and thus begin our
- understanding of the Host.
- V) Host
- - Where we master the Host code, through a long and tortuous journey.
- Indeed, it is here that our hero is tested in the Bit of Despair.
- VI) Switcher
- - Where our understanding of the intertwined nature of Guests and Hosts
- is completed.
- VII) Mastery
- - Where our fully fledged hero grapples with the Great Question:
- "What next?"
- make Preparation!
