No addition of the new function in libvirt-gobject.sym?

Same here, domain

xml shouldn't be const and need to be g_freed when it's no longer needed.

Here I'd do
   g_mutex_lock(priv->lock);
   g_hash_table_insert(priv->domains,
                       (gpointer)gvir_domain_get_uuid(domain),
                       g_object_ref(domain));
   g_mutex_unlock(priv->lock);

   return domain;

to make it clearer that the hash table needs a ref on the object. The way
it's written, I had to check how priv->domains is declared to make sure
that wasn't an extra _ref.
