  Hi!

At least on s390x, you can also specify the memory backend via the -machine 
option instead of using the -numa option, e.g.:

  qemu-system-s390x -machine memory-backend=mem \
   -object memory-backend-file,id=mem,...

Not sure whether that works on other architectures, too, though. Stefan, 
David, do you know?
