lguest: the documentation, example launcher A brief document describing how to use lguest. Because lguest doesn't have an ABI we also include an example launcher in the Documentation directory.

# This creates the demonstration utility "lguest" which runs a Linux guest.
lguest: fix up compilation after move ed16648eb5b86917f0b90bdcdbc857202da72f90 "Move kvm, uml, and lguest subdirectories" broke the lguest example launcher. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

lguest: clean up warnings in demonstration launcher. These days the headers we use are in glibc. If those are too old, you can add the -I lines to get the kernel headers.

Introduce guest mem offset, static link example launcher In order to avoid problematic special linking of the Launcher, we give the Host an offset: this means we can use any memory region in the Launcher as Guest memory rather than insisting on mmap() at 0. The result is quite pleasing: a number of casts are replaced with simple additions. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
