Yes, we need such a smoke test for all targets.

I toyed with it myself, but I haven't been able to go beyond the crude
hackery we discussed about a year ago:
https://lists.nongnu.org/archive/html/qemu-devel/2012-08/msg01197.html

The problem is that many targets have mandatory options (fun oxymoron),
such as -kernel or -pflash.

If I understand your approach correctly, you solve it by making these
mandatory options optional when qtest_enabled().

My idea was to create suitable dummy images, so we can provide the
mandatory options.  Guest won't be happy, but that's fine, as this smoke
test doesn't want to run any guest code.

I like my idea better, because with it we can run unmodified standard
code.  No testing of qtest_enabled().

However, you've got patches, and I haven't, and that means I like your
*patches* infinitely more than mine ;)
