This sounds very much like a job for DNS + DHCP with fixed MAC/IP
mappings. libvirt might want to offer this IP lookup capability for
adhoc setups, but it encourages very bad administration practices.

My objection isn't so much to where this should live, as that it's
unnecessary at best and wallpapers over broken setups/apps at worst.
