I would suggest to try user mode linux (UML). With the
current kernel versions you don't need any patches anymore,
neither for the host nor for the uml-kernel itself.
The first relevant function there should be
init/main.c:start_kernel
To get started, refere to
http://user-mode-linux.sourceforge.net/UserModeLinux-HOWTO.html
In case of problems,
http://www.mail-archive.com/user-mode-linux-user@xxxxxxxxxxxxxxxxxxxxx/index.html
is a good source of information.
Just a few tips:
- use a new folder for the UML kernel, dont work on the same folder you
use to build your host kernel
- don't use versions of gdb older than 6.3! I had an older version
before and lots of trouble to get startet.
greetings
Thorsten
