Automatically detecting the format is dangerous for raw images, write
operations on block 0 will be restricted.
Specify the 'raw' format explicitly to remove the restrictions.
Check the integrity of the image you've downloaded.
No, that warning happens on correct images. It just means that qemu does
not dare touching the beginning of an image which was not asserted to be
a raw image.

I believe the fix is to add "format=raw" to the end of the line, like so:
$ kvm -m 1G -drive file=$(echo debian-hurd*.img),cache=writeback,format=raw
At least, this seemed to work for me.
