Also, until 3.2.0 it was mandatory to restart the virtual network after
configuring the libvirt_guest module (I've updated the wiki accordingly).

This is the problem. Libvirt is not the one who's assigning IP addresses
and thus the NSS module doesn't work.

By having libvirt network assign IP addresses. Generally, <interface
type='network'/> is what you should look for.
