You need to have lguest working for the lguest tutorial. We had a preparation
BoF, and here's what we ended up with (thanks everyone!)
- Get a 2.6.23 kernel
- Make sure CONFIG_EXT2=y so you can read the root image.
- Build your kernel with CONFIG_LGUEST=m (here are pre-built kernel trees for
Debian unstable and Ubuntu 7.10 (Gutsy).)
- Install the kernel on your machine.
- cd into Documentation/lguest/ and type "make" to build the "lguest" launcher binary (you will need the zlib headers and static libraries).
- Grab a simple root image I use the Xen-test tiny image.
- Reboot into your 2.6.23 image.
- sudo modprobe lg
- Run the lguest launcher like so:
sudo /usr/src/linux-2.6.23/Documentation/lguest/lguest --block=initrd-1.1-i386.img 128 /boot/vmlinuz-126.96.36.199 root=/dev/lgba
- If you see the "sh" prompt, you're ready for the tutorial!
There's also a Qemu image
with instructions but you need to build outside and install updates into the image.
