I think the choice of subnet should be added to the configuration
file. A default of 127.28.0.0/16 is fine, as long as people can
override it easily if it causes trouble.

The Sys::Virt::TCK->generic_network method would then return you
a Sys::Virt::TCK::NetworkBuilder instance with the ip details
filled in from the config file. So all test cases should 'just work'
if they use the convenience APIs for building network XML.
