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.

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> 2007-10-22 09:03:26 +08:00			`all: lguest`
