Configure the Networking service for bare metal provisioning
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
You need to configure Networking so that the bare metal server can communicate
|
|
with the Networking service for DHCP, PXE boot and other requirements.
|
|
This section covers configuring Networking for a single flat network for bare
|
|
metal provisioning.
|
|
|
|
You will also need to provide Bare Metal service with the MAC address(es) of
|
|
each node that it is provisioning; Bare Metal service in turn will pass this
|
|
information to Networking service for DHCP and PXE boot configuration.
|
|
An example of this is shown in the :ref:`enrollment` section.

#. Edit ``/etc/neutron/plugins/ml2/ml2_conf.ini`` and modify these:
|
|
|
|
.. code-block:: ini
|
|
|
|
[ml2]
|
|
type_drivers = flat
|
|
tenant_network_types = flat
|
|
mechanism_drivers = openvswitch
|
|
|
|
[ml2_type_flat]
|
|
flat_networks = physnet1
|
|
|
|
[securitygroup]
|
|
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
|
|
enable_security_group = True
|
|
|
|
[ovs]
|
|
bridge_mappings = physnet1:br-eth2
|
|
# Replace eth2 with the interface on the neutron node which you
|
|
# are using to connect to the bare metal server
|
|
|
|
#. If neutron-openvswitch-agent runs with ``ovs_neutron_plugin.ini`` as the input
|
|
config-file, edit ``ovs_neutron_plugin.ini`` to configure the bridge mappings
|
|
by adding the [ovs] section described in the previous step, and restart the
|
|
neutron-openvswitch-agent.
|
|
|
|
#. Add the integration bridge to Open vSwitch:
|
|
|
|
.. code-block:: console
|
|
|
|
$ ovs-vsctl add-br br-int
|
|
|
|
#. Create the br-eth2 network bridge to handle communication between the
|
|
OpenStack services (and the Bare Metal services) and the bare metal nodes
|
|
using eth2.
|
|
Replace eth2 with the interface on the network node which you are using to
|
|
connect to the Bare Metal service:
|
|
|
|
.. code-block:: console
|
|
|
|
$ ovs-vsctl add-br br-eth2
|
|
$ ovs-vsctl add-port br-eth2 eth2
|
|
|
|
#. Restart the Open vSwitch agent:
|
|
|
|
.. code-block:: console
|
|
|
|
# service neutron-plugin-openvswitch-agent restart
|
|
|
|
#. On restarting the Networking service Open vSwitch agent, the veth pair
|
|
between the bridges br-int and br-eth2 is automatically created.
|
|
|
|
Your Open vSwitch bridges should look something like this after
|
|
following the above steps:
|
|
|
|
.. code-block:: console
|
|
|
|
$ ovs-vsctl show
|
|
|
|
Bridge br-int
|
|
fail_mode: secure
|
|

|
|

|
|

|

|
|

#. Create the flat network on which you are going to launch the
|
|
instances:
|
|
|
|
.. code-block:: console
|
|
|
|
$ neutron net-create --tenant-id $TENANT_ID sharednet1 --shared \
|
|
--provider:network_type flat --provider:physical_network physnet1
|
|
|
|
#. Create the subnet on the newly created network:
|
|
|
|
.. code-block:: console
|
|
|
|
$ neutron subnet-create sharednet1 $NETWORK_CIDR --name $SUBNET_NAME \
|
|
--ip-version=4 --gateway=$GATEWAY_IP --allocation-pool \
|
|
start=$START_IP,end=$END_IP --enable-dhcp
