Right here is where you should stick a --- marker.

It's okay to have a duplicate one; but the main point is that the v2
changelog is useful to reviewers but not to the git log; and anything
after the --- marker gets omitted by 'git am' when a maintainer accepts
your patch into their pull request.

This test starts as a duplicate of test_qemu_find_opts; I guess that's
okay (having both tests means a bit more insight into what broke if one
fails but the other passes).

s/dinamically/dynamically/

That's trivially fixable, so feel free to add:
