Are you sure?  Which ones don't work?

I've never had a problem with the first two:
$ wget http://people.debian.org/~sthibault/hurd-i386/debian-hurd.img.tar.gz
$ tar -xz < debian-hurd.img.tar.gz

I have had problems with the last command:

$ kvm -m 1G -drive cache=writeback,file=$(echo debian-hurd-*.img)

mainly that "kvm" is not the command you use.  I've always had to run
  qemu-system-i386.

My script looks like so:

#!/bin/bash
modprobe kvm
modprobe kvm_intel
cd ~/programming/gnu/hurd/vm/
MEMORY=2G
FILE=debian-hurd-2017-06-13.img
# If I ever need to add a cdrom
    echo "running ssh"

qemu-system-i386 -m $MEMORY -net nic                          \
                     -net user,hostfwd=tcp:127.0.0.1:2222-:22     \
                     -drive file=$FILE,cache=writeback,format=raw \
                     -enable-kvm                                  \
                     -curses                                      \
                     -no-reboot;
                     # -curses                                      \
                     # -machine kernel_irqchip=off                  \

P.S. I have a video at youtube explaining how to contribute to the Hurd
wiki.  My channel is called the GNU Guy.  If you do decide to edit the
wiki, send your patch to bug-hurd.  No one uses the web-hurd mailing list.
