You can always use Designate. That is the "real" DNS for Openstack.

I'm not exactly sure HOW to use the "Neutron DNS thingie". Maybe it just
don't work for me because I managed to set that to the same domain name
that I later used in Designate.. Haven't bothered to fix it, I rather
use Designate.

That's "easy" (setting up Designate is "a breeze" compared to Neutron :).
You just set the "dns_domain" property on the network and the "dns_name"
on the instance and it's automatic..

If I remember correctly, Designate can also do reverse DNS, but I ended
up in some weird corner case so that it don't work for me. So I had to
setup my own reverse DNS domain (a .in-addr.arpa.) and add entries manually
to that. That's not a biggie for me, I rather have it that way anyway.
