[libvirt] [PATCH v2 0/5] network: Add support for local PTR domains

I run a system dnsmasq to be able to forward specific DNS requests to specific servers. And I have it configured for both forward and reverse lookups. Another dnsmasq is started for a virtual network with domain "virt". The system dnsmasq knows it needs to forward any requests for the "virt" domain and corresponding PTR domain to the dnsmasq started by libvirt. The problem is dnsmasq forwards queries for unknown names to the upstream name server (which is the system instance in my case). One can get nice endless loops of DNS requests pretty easily. Forward loops can be avoided by specifying localOnly='yes', but there was no way to avoid reverse lookup loops. And this is what I'm trying to address in the following patches.
