Hurd on QEMU
I will assume you have already installed QEMU.
You will need the debian grub boot disk package for the floppy.img . The floppy boot image is called grub-0.95-i386-pc.ext2fs.gz and you can gunzip this and rename it to floppy.img if you like.
First off use qemu-img to create a disk image. I set mine to 2 gigabytes.
qemu-img create hd0.img 2G
Now you will need a cdrom image or an install CD. I will use debian/hurd K9 in this example. I use a floppy image with GRUB on it to boot the system, after i'm done installing. The first time you run it you'll want to use -boot d to boot off the cdrom.
qemu -hda hd0.img -cdrom debian-K9-hurd-i386-CD1.iso -fda floppy.img -boot d
Now at his point do the regular install using =hd0= as your harddrive. Partition it and install the base system. Instead of rebooting, just stop QEMU (it'll keep booting off the cdrom).
*Important:* Debian K8's gnumach will not boot in QEMU unless you use QEMU's -isa command line option (and niether will Debian K9).
Now run your image with floppy booting and finish the install (=./native-install= .. etc)
qemu -isa -hda hd0.img -cdrom debian-K9-hurd-i386-CD1.iso -fda floppy.img -boot a
So far I haven't been able to get networking going, it seems as if gnumach is not finding the ethernet device, although I haven't really looked into it that far.
Mounting disk image
If you want to mount your disk image, you'll either have to use mount or a program called [[lomount]] to do this. If you are going to use mount, you will need to know the correct offset.
mount -o loop,offset=OFFSET hd0.img /mnt/diskimage

To find the offset, you can run (from your host OS):
fdisk -ul hd0.img
and multiply sectors by the # of bytes given

HURD LiveCD from superunprivileged.org on QEMU
Download the image fromhttp://www.superunprivileged.org/hurd/live-cd/. Uncompress with appropriate program on your OS. Run qemu with following option: "-M isapc" like and without accelerator
qemu -M isapc -cdrom hurd-live-cd-20051117.iso -boot d
