This patch actually prompted me to check s390, and the mentioned
command line works fine.

However, if we start a qemu with no guest memory defined and then call
dump-guest-memory without filtering, we get a core dump instead of a
guest dump (s390x or x86_64, machine none).

I can take a stab at fixing that, unless someone beats me to it.
