Which of course only works with new enough QEMU that is known to support QMP
(which BTW we detect by checking the version number).
Or you could just try the -qmp option and if QEMU exits, it doesn't support it.
That's going to be a lot more reliable than checking a version number.

Anyway, the fix is easy,
we just need to assume micro is 0 if it's missing instead of requiring it to
be present. A fix will come soon.
