I think what it means that, if the file permission for the disk image in
host OS is read only for the user running qemu, then it is not saying
that clearly. May be qemu should just exit as soon as it sees that image
is read only. I am not sure if in some kind of mode it is possible to
run a VM without the need of writing anything on the image. If that is
the case then probably it should give an option or default to run in
that mode under such circumstances.
