Why we can return a RP which has a specific trait but we won't consume any resources on it? If the case is that we request two VFs, and this two VFs have different required traits, then that should be granular request. > > > __________________________________ > ________________________________________ > OpenStack Development Mailing List (not for usage questions) > Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev >
