features:
|
|
- Adds support for `routed networks
|
|
<https://docs.openstack.org/neutron/latest/admin/config-routed-networks>`_
|
|
when using the ``flat`` network interface. This feature requires the
|
|
``baremetal`` ML2 mechanism driver and L2 agent from the
|
|
`networking-baremetal <https://docs.openstack.org/networking-baremetal>`_
|
|
plugin. See the `networking configuration documentation
|
|
<https://docs.openstack.org/ironic/latest/install/configure-networking.html>`_
|
|
for more details.
|
|
upgrade:
|
|
- |
|
|
The ``baremetal`` ML2 mechanism driver and L2 agent should now be used
|
|
with the ``flat`` network interface. When installed, the ``baremetal``
|
|
mechanism driver and agent ensure that ports are properly bound in the
|
|
Networking service. Installation and configuration of the ML2 components
|
|
are documented in the `networking-baremetal project documentation
|
|
<https://docs.openstack.org/networking-baremetal>`_.
|
|
|
|
Without the ML2 mechanism driver and L2 agent, the Networking service's
|
|
ports will not be correctly bound. In the Networking
|
|
service, ports will have a ``DOWN`` status, and the ``binding_vif_type``
|
|
field equal to ``binding_failed``. This was always the status for the
|
|
``flat`` network interface ports prior to the introduction of the
|
|
``baremetal`` mechanism driver. For a non-routed network, bare metal nodes
|
|
can still be deployed and are functional, despite this port binding state
|
|
in the Networking service.
|
|
fixes:
|
|
- Fixes an issue where the Networking service would reject port bindings
|
|
with the ``flat`` network interface because no host would match the
|
|
*host-id* used in such configurations. The ``flat`` network interface no
|
|
longer requires a networking agent (such as ``neutron-openvswitch-agent``)
|
|
to be run on the ``nova-compute`` proxy node which executes the ironic virt
|
|
driver. Instead, the interface uses the `baremetal mechanism driver
|
|
<https://docs.openstack.org/networking-baremetal>`_.
