--- upgrade: - | If you have overridden your ``openstack_host_specific_kernel_modules``, please remove its group matching, and move that override directly to the appropriate group. Example, for an override like: .. code-block:: yaml - name: "ebtables" pattern: "CONFIG_BRIDGE_NF_EBTABLES" group: "network_hosts" You can create a file for the network_host group, inside its group vars folder ``/etc/openstack_deploy/group_vars/network_hosts``, with the content: .. code-block:: yaml - name: "ebtables" pattern: "CONFIG_BRIDGE_NF_EBTABLES"
