There's several unresolved RFEs for the <network> bridge driver that are essentially requests to add XML wrappers for underlying dnsmasq options. This series adds a dnsmasq xmlns namespace for <network> XML that allows passing option strings directly to the generated dnsmasq config file. It will allow motivated users to work around libvirt until those types of RFEs are properly implemented.
This all looks like a reasonable facsimile of the qemu:commandline stuff, and it worked in my tests (including not creating any problems with all the existing networks I have on my test system).
My one reservation would be that it will tend to discourage adding *supported* methods of configuring things that people will instead use this backdoor to implement. But on the other hand, it makes it possible to do new things without needing to wait for an officially supported method (which could take a very long time, or simply never happen, as we've seen).
(Actually I for some reason thought we already *had* support for the specific example you used - CNAME records. I guess I had lumped it in with SRV and TXT records in my memory. It really should be straightforward to do, and should still be done, but that shouldn't stop this patch series from going in).
