I'm not an OpenBSD user, so I'm more than happy if you can help the
upstream community to test QEMU codebase on this OS. Testing helps us to
avoid code rot.

What we currently use to run tests is the 'tests/vm/openbsd' script.
The script itself doesn't document how it was built, but looking at the
commit of his introduction fdfaa33291eb we have:

    The image is prepared following instructions as in:

Phil.
