No you didn't.

Yeah, this is what I had in mind. So if we ever add support for <listen>
child elements we may wish _set_listen to be reserved just for this case:

void
gvir_config_domain_graphics_spice_set_listen(GVirConfigDomainGraphicsSpice *graphics,
                                             GList *listen);

Same scenario is already happening for gvir_config_domain_set_devices().

what about

_listen_address(GVirConfigDomainGraphicsSpice *, const char *addr);

with @addr being either IP or hostname (in fact anything that is acceptable for libvirt)?
