As far as I can see, the difference bwteen stroustrup style and yours is
a few tweaks to c-offsets-alist and c-hanging-braces-alist. I'm not
sure how to do that from .dir-locals.el.

The obvious way is to check the buffer-local variables. Buffer-local
variable c-indentation-style is the name of the style in use. Without
anything in .emacs or local variables, it's "gnu". With your
(c-add-style "qemu" qemu-c-style) in .emacs, it should be "qemu". With
Dan's .dir-locals.el, it should be "stroustrup".
When you can't or don't want to create or modify a .dir-locals.el, you
can do something like this instead:
(dir-locals-set-class-variables 'qemu '((c-mode . ((c-file-style . "qemu")))))
(dir-locals-set-directory-class "~/work/qemu" 'qemu)
This *overrides* .dir-locals.el in my testing.
