gvir_domain_new_device(GVirDomain *domain, GVirConfigDomainDevice *config)
maybe ?
Having the argument that is always non-NULL first feels better to me.

I'd have a slight preference for something like
switch (G_OBJECT_TYPE(config)) {
case GVIR_CONFIG_TYPE_DOMAIN_DISK:
type = GVIR_TYPE_DOMAIN_DISK;
break;
...
but I'm fine with either version.

slight preference for g_list_prepend (much more efficient when the list is
big).

The individual elements need to be unref'ed too as well as config.

Try to get the list sorted/consistent with the other entries.
