This is a howto on how to get a working image of Hurd/L4 with qemu, on ia32 arch.
You will need the following :
* automake 1.7 (or greater)
* autoconf 2.53 (or greater)
* grub
* the CVS version of hurd-l4, which you can retrieve from the savannah server: `cvs -z3 -d:ext:anoncvs@savannah.gnu.org:/CVSROOT/hurd co hurd-l4`
* two flavours of Pistachio, the L4 kernel, which can be found at <http://www.l4ka.org/projects/pistachio/download.php>. Take both the source (`pistachio-0.4.tar.bz2`) and the demodisk for ia32 (`pistachio-ia32-0.4-demodisk.bin.bz2`)
We will begin with the hurd itself (these steps are taken from the `README`).
$ cd hurd-l4
$ autoreconf -f -i -s
You shouldn't have any warnings with this autoreconf. If that is not the case, it probably hasn't used the good version of automake or autoconf. For instance, on Gentoo Linux, you must set WANT\_AUTOCONF to 2.5 and WANT\_AUTOMAKE to 1.7.
$ ./configure --enable-maintainer-mode --prefix=/l4
$ make
$ make install
$ mkdir /l4/boot
$ install -s laden/laden /l4/boot
$ install -s wortel/wortel /l4/boot
$ install -s physmem/physmem /l4/boot
$ install -s task/task /l4/boot
$ install -s deva/deva /l4/boot
$ install -s ruth/ruth /l4/boot
Now we'll prepare the Pistachio kernel :
$ tar xjvf pistachio-0.4.tar.bz2
$ cd pistachio-0.4
We must apply some patchs for it to work properly with The Hurd. They are located in `hurd-l4/README`:
$ patch -p1 < ../hurd-l4/README
We will first compile sigma0 (and some other tools) :
$ cd user
$ mkdir BUILDDIR
$ cd BUILDDIR
We need to change the linkbase of sigma0 :
$ ../configure --with-s0-linkbase=0x40000 --prefix=/l4
$ make
$ make install
And now the kernel itself :
$ cd ../../kernel
You can use any builddir as long as the directory doesn't yet exist.
$ make BUILDDIR=/tmp/pistachio-build
$ cd /tmp/pistachio-build
$ vi Makeconf.local
You should modify the first three lines to :
ARCH=ia32
CPU=i586
PLATFORM=pc99
now run:
$ make menuconfig
Set the options as they fit you but for qemu to work, you must have the following hardware :
IA32 Basic Architecture
Pentium1 Processor Type
You can now:
$ make
You should obtain a file named ia32-kernel into your build directory.
$ cp ia32-kernel /l4/boot
$ cp /l4/libexec/l4/sigma0 /l4/boot
We now have to modify a little bit the demodisk to use the kernel and servers we just obtained :
$ mkdir qemu
$ mkdir qemu/image
$ cd qemu
$ cp ~/pistachio-ia32-0.4-demodisk.bin.bz2 .
$ bunzip2 pistachio-ia32-0.4-demodisk.bin.bz2
$ mount -o loop pistachio-ia32-0.4-demodisk.bin image
$ cd image/boot
$ cp /l4/boot/* .
$ cd grub
$ vi menu.lst
Your `menu.lst` should look like :
title GNU Hurd on L4
kernel /boot/laden -D -o serial,uart1,speed=9600
module /boot/ia32-kernel
module /boot/sigma0
module /boot/wortel -D -o serial,uart1,speed=9600
module /boot/physmem
module /boot/task
module /boot/deva
module /boot/task
module /boot/ruth
The two -D are intended for debug, you can delete them if you want. It is possible that filenames are limited to 8 characters, check your image/boot directory for ia32-kernel. If it has been renamed into ia32-ker, modify the according line in menu.lst
The image is now ready :
$ cd ../../../
$ umount image
We can launch qemu:
$ qemu -dummy-net -serial stdio -fda pistachio-ia32-0.4-demodisk.bin -boot a
Congratulations, you just booted Hurd/L4 ! To switch the KDB mode from character (I find it unusable) to command line, type

I didn't bother to licence it as it is so small, but consider it is under some sort of creative commons that allows redistribution and modification. <br /> -- Alexandre Buisse <nattfodd@gmail.com>
