networking-midonet

This is the official Midonet Neutron plugin.

The current set of supported versions of MidoNet are:

• v2015.06
• v5.x

NOTE: MidoNet recently changed its versioning scheme. v5.0 is what used to be called v2015.09.

How to Install

For productional deployments, we recommend to use a package for your distribution if available:

http://builds.midonet.org/

You can install the plugin from the source code by running the following command:

$ sudo python setup.py install

The plugin requires python-midonetclient package, which is usually available along with other midonet packages. It’s recommended to use the same version of python-midonetclient and midonet-cluster. Alternatively, you can install python-midonetclient from source:

$ sudo pip install -e 'git://github.com/midonet/midonet.git@master#egg=midonetclient&subdirectory=python-midonetclient'

Core plugin and L3 service plugin

The following entry in /etc/neutron/neutron.conf enables MidoNet as the Neutron plugin. There are two plugins to choose from.

Plugin v1, which is compatible with MidoNet v2015.06:

[DEFAULT]
core_plugin = midonet

Plugin v2, which is compatible with MidoNet v5.0 and beyond. It works with a separate L3 plugin which you need to add to the list of service plugins:

[DEFAULT]
core_plugin = midonet_v2
service_plugins = midonet_l3

ML2 mechanism and type drivers

ML2 mechanism driver and type drivers are available. They are compatible with MidoNet v5.0 and beyond:

[DEFAULT]
core_plugin = ml2
service_plugins = midonet_l3

[ml2]
tenant_network_types = midonet
type_drivers = midonet,uplink
mechanism_drivers = midonet

Interaction with Neutron agents

For v2015.06, OpenStack deployment with MidoNet works with Neutron DHCP and Metadata agents.

For MidoNet v5.0 and later, no Neutron agents are necessary.

For details, please refer to MidoNet documentation:

https://docs.midonet.org

Interface driver

Neutron agents use interface driver to connect themselves into the datapath. In case of MidoNet, they should be configured with the MidoNet interface driver.:

[DEFAULT]
interface_driver = midonet

FWaaS

Starting v5.0, MidoNet implements Neutron FWaaS extention API.

To configure it, add the following service plugin to the service_plugins list in the DEFAULT section of /etc/neutron/neutron.conf:

[DEFAULT]
service_plugins = midonet_firewall

NOTE: No need to configure Firewall Driver at all. It’s irrelevant because this plugin does not use Neutron L3 agent.

VPNaaS

Starting v5.1, MidoNet implements Neutron VPNaaS extension API.

MidoNet plugin implements VPNaaS as a service driver. To configure it, add the following entries in the Neutron configuration file /etc/neutron/neutron.conf:

[DEFAULT]
service_plugins = vpnaas

[service_providers]
service_provider=VPN:Midonet:midonet.neutron.services.vpn.service_drivers.midonet_ipsec.MidonetIPsecVPNDriver:default

NOTE: This plugin does not use Neutron VPNaaS agent.

Gateway Device Service

Starting v5.1, MidoNet implements Gateway Device Service vendor extension API.

To configure it, add the following service plugin to the service_plugins list in the DEFAULT section of /etc/neutron/neutron.conf:

[DEFAULT]
service_plugins = midonet_gwdevice

L2 Gateway Service

Starting v5.1, MidoNet implements Neutron L2 Gateway Service extension API. The implementation differs slightly from upstream. Please check the following spec to see the differences:

http://docs.openstack.org/developer/networking-midonet/specs/mitaka/border_gw.html

MidoNet plugin implements L2 Gateway Service as a service driver. To configure it, add the following service plugin to the service_plugins list in the DEFAULT section of /etc/neutron/neutron.conf:

[DEFAULT]
service_plugins = midonet_l2gw

In addition, configure the service provider in the ‘service_providers’ section of L2 Gateway plugin configuration file /etc/neutron/l2gw_plugin.ini:

[service_providers]
service_provider = L2GW:Midonet:midonet.neutron.services.l2gateway.service_drivers.l2gw_midonet.MidonetL2gwDriver:default

Magnum

Starting v5.2, MidoNet can be used for Magnum deployment with the following workaround.

Note: MidoNet doesn’t provide LBaaS v2 functionality. You may need to disable it in your template.

BGP dynamic routing service

Starting v5.2, MidoNet implements Neutron BGP dynamic routing service extension API. The implementation differs from upstream as follows:

• Router that is treated as bgp-speaker can be specified explicitly.
• Bgp-peer can relate to only one bgp-speaker.
• Binding network to bgp-speaker must be done before associating peers.
• Removing network from bgp-speaker must be done after all peers are disassociated from the bgp-speaker.
• Only one network can be associated with a bgp-speaker.
• Advertise_floating_ip_host_routes and advertise_tenant_networks are ignored.
• Attached network to the router and destination network in extra routes on the router are showed as advertised routes.

To configure it, add the following service plugin to the service_plugins list in the DEFAULT section of /etc/neutron/neutron.conf:

[DEFAULT]
service_plugins = midonet_bgp

Logging Resource Service

Starting v5.2, MidoNet implements Neutron Logging Resource Service extension API.

To configure it, add the following service plugin to the service_plugins list in the DEFAULT section of /etc/neutron/neutron.conf:

[DEFAULT]
service_plugins = midonet_logging_resource

Firewall log is managed by Quota. Default value of firewall log is 10 that is same number as firewall. Basically, both Quota value for firewall and firewall log should be aligned. To tune it, change value of quota_firewall_log in the quotas section of /etc/neutron/neutron.conf.

Tap-as-a-Service

Starting v5.2, MidoNet implements Tap-as-a-Service extension API.

MidoNet plugin implements TaaS as a service driver. To configure it, add the following entries in the Neutron configuration file /etc/neutron/neutron.conf:

[DEFAULT]
service_plugins = taas

In addition, configure the service provider in the ‘service_providers’ section of TaaS plugin configuration file /etc/neutron/taas_plugin.ini:

[service_providers]
service_provider = TAAS:Midonet:midonet.neutron.services.taas.service_drivers.taas_midonet.MidonetTaasDriver:default

QoS

With the latest development version of MidoNet, ML2 plugin with MidoNet mechansim driver supports Neutron QoS extension.

Note: MidoNet monolithic plugins (either v1 or v2) do not support QoS core resource extension.

QoS service plugin

QoS service plugin can be configured in the Neutron server configuration file /etc/neutron/neutron.conf:

[DEFAULT]
service_plugins = qos

[qos]
notification_drivers = midonet

QoS core resource extension

QoS core resource extension for ML2 plugin can be configured in the Neutron server configuration file /etc/neutron/neutron.conf:

[ml2]
extension_drivers = qos

Horizon

Starting with Newton, Horizon has built-in support for MidoNet network types.

To enable it, add the following configuration to the OPENSTACK_NEUTRON_NETWORK dict in local_settings.py:

'supported_provider_types': ['midonet', 'uplink'],
