The bug being fixed here is a bit niche (I don't think many
people build with KVM support only) so I would not worry
about backporting it all the way to 7.2. I'm not sure about
the best approach for 9.0 (which is why I left that note rather
than actively suggestion one or the other) -- it depends whether
you value more "backport the change that's actually been tested
by being in mainline" or "make the minimal set of changes in the
stable branch"...
