Since Avahi is working only part of the time, it would be nice to implement https://github.com/uyuni-project/uyuni/wiki/Libvirt-DNS-and-DHCP-without-Avahi into a default libvirt network. This would help newcomers to get rid of the DNS issues.

The generated NAT network should be prefixed with the machine's prefix to avoid hijacking other networks.

Probable to do list:

auto-generate MACs for our various VMs (client, server, etc.)
create the new libvirt network in NAT mode, ensuring the previous setups like bridged setup still work
populate the DHCP tables of dnsmasq with the MACs and corresponding IPs
poulate the DNS tables of dnsmasq with the IPs and corresponding domain names
