Sure, but, do you mean separating the "readonly=on" and the "writable
file" changes?  Or separating those two from the ISO url code style
change?

Yes, but more importantly, adding both "readonly=on" and "media=cdrom"
to the tests under machine_aarch64_sbsaref.py do the trick.  Now, the
behavior explained in my previous response still warrants investigation
IMO.
