Maybe...

Nice, seems to work.

I actually was on that page, but I must have missed that bit...

No, thats not it. I do not want to set single hosts, I want to tell
dnsmasq to read an additional hosts-file. In the normal dnsmasq.conf
this is done via addn-hosts=, and that appears in the conf-file for
the network called e.g. WHATEVER:

addn-hosts=/var/lib/libvirt/dnsmasq/WHATEVER.addnhosts
