This section should read:

  qemu-system-x86_64 -m 1024 -smp 1 \
    -net user -net nic,model=3Dvirtio -boot menu=3Don \
    -drive file=3Dguixsd.img \

(It=E2=80=99s a typo in the manual fixed in commit

This is just a warning.

However, you really need networking support in the VM to install GuixSD.

HTH!
