Newton Series Release Notes¶
Non-IP traffic is allowed in L2 and L3 Domains. The default_allow_non_ip setting determines if non-ip traffic is allowed in Nuage specific L2 and L3 domains.
Add new configuration parameters for the Cisco UCSM ML2 driver
The following new configuration parameters are now being supported by the UCSM ML2 driver. * ucsm_https_verify * sp_template_list * vnic_template_list
Optionally users can set device_driver value in lbaas_agent.ini to $::os_service_default
Nexus: Configuration clean-up
This changeset deprecates old configurations not used in the code and others to be aged out mostly due to code improvements such as implementation of the Nexusu RESTAPI driver. The RESTAPI driver replaces use of the ncclient driver. The ncclient driver will be removed along with any tuning configuration that goes with it.
Adds ovs_integration_bridge config option in neutron.conf and adds ovs_veth_use config option in lbaas_agent.ini
Additional support for Nuage is added in neutron, as a result of which Nuage can be plugged into neutron as ML2 mechanism driver. This feature is in addition to the option of usign Nuage as the core plugin. This change adds neutron::plugins::ml2::nuage
Added nuage configuration file under neutron-server configuration directory so that neutron-server can pick up the configuration file on startup. This change creates nuage_plugin.conf symlink under the folder /etc/neutron/conf.d/neutron-server.
Add minimize_polling parameter to ovs ml2 agent class.
Add type and provider to mange rootwrap.conf file mainly to manipulate XenServer connection parameters.
Adds the enable_new_agents config option to the neutron server
Passes parameter to keystone authtoken define to manage python-memcache package install.
The enable_headers_parsing option was added to the server manifest. This enables the http_proxy_to_wsgi middleware to process SSL-related headers.
Opendaylight OVS provider_mappings argument now accepts an array type.
Neutron modified the way that Agents connect to OVSDB server to configure OVS tap ports, etc by using the OVSDB server URI rather than the ovs-vsctl client. In ODL deployments, OVSDB server is never configured to listen on a port and therefore Neutron Agent configuration fails. This fixes that problem by configuring multiple managers, including a local listener by default on a non-standard port for OVSDB server. This way Neutron Agents are able to talk to OVSDB while OVS is also still connected to ODL.
The package name for nuage neutron plugin changed due to decomposition of vendor plugins from neutron package to per-vendor packages.
Add overlay_ip_version options support to ml2 plugin settings.
Add oslo.messaging rabbit_transient_queues_ttl parameter support.
Configure keystonemiddleware in a consistent way using modern parameters
Add certificates configuration options for lbaas service.
Midonet v5.x plugin doesn’t rely anymore on a custom DHCP agent, also it only uses a subproject for db sync instead of the old method of overriding the neutron-db-sync completelly.

neutron::server::region_name is deprecated, use neutron::keystone::authtoken::region_name instead
allow_paginationconfiguration options are deprecated and will be removed in a future release.
Parameters of type dict must be at the end of the shell command to not cause conflict with the network name. Neutron cli picks up the network name as the first parameter without “–” prefix, thus tresting type=dict as the network name instead of the real network name because it comes before. By providing the special dictionary type commands after the network name the behaviour of the cli is bypassed and neutron takes the network name and proceeds interpreting parameters with special format ( not in the form of –<param>=<value> )
Add ‘binding_host_id’ and ‘binding_profile’ support to neutron_port custom type.
Add the ability to specify the a name string for the router_id in neutron_l3_agent_config using the transform_to argument.

Added a provider to configure VFs for SR-IOV interface
Switch-on lbaasv2 by default instead of lbaasv2 to follow what upstream Neutron is doing in https://review.openstack.org/286381 and also switch default device_driver to be neutron_lbaas.drivers.haproxy.namespace_driver.HaproxyNSDriver
Previously OVN plugin for Neutron used to be a core plugin. With the recent changes in networking-ovn project, OVN is plugged in to neutron as an ml2 mechanism driver.

This adds defined anchor points for external modules to hook into the software install, config and service dependency chain. This allows external modules to manage software installation (virtualenv, containers, etc) and service management (pacemaker) without needing rely on resources that may change or be renamed.
The keystone auth class has been updated to provide a default service_name to allow a user to specify a custom auth_name that may not contain the name of the service.
Adds the ability to manage the memcached servers for keystone_authtoken in neutron::server
Add ‘dnsmasq_dns_servers’ option support to dhcp agent settings.

VPNaaS service_provider was being configured in a file not being loaded up by neutron server. It has been consolidated with lbaas service configuration into neutron.conf.
_verbose_ option is deprecated and will be removed in future
[DEFAULT]/network_device_mtu option is deprecated and will be removed in Newton. However, new [ml2]/segment_mtu is deprecated too according to neutron/common/config.py. New [DEFAULT]/global_physnet_mtu should be used.
The lbaas v2 agent package ensure in neutron services lbaas has been deprecated, the agent should be installed from neutron agents lbaas.

Added python-neutron-lbaas package to be installed with neutron::services::lbaas. this removes a dependency of installing agent on neutron api server to enable the lbaas service.
Fixes bug 1560716 so LinuxBridge configuration file path is the correct one for RDO & UCA packaging.
If Neutron is installed from Ubuntu packages, neutron-server and openvswitch/linuxbridge agents use separate files to load configuration related to ML2 plugin. So in order to use security groups firewall_driver value should be passed to both configuration files (ml2_conf.ini and openvswitch_agent.ini)
Metadata agent config should be applied after package installation.
Add normal bug fixes here, or remove this section.
The package name for the midonet neutron plugin previously used an older naming syntax from times passed that no longer existed in current repositories. To fix this issue the package name was updated to “python-networking-midonet” which is provided by third repository from Midokura.
PLUMgrid neutron plugin assumes the default keystone v2 for a given deployment. The issue is fixed by switching the default config to keystone v3.
PLUMgrid neutron plugin isn’t able to specify nova metadata subnet, that is used by PLUMgrid metadata implementation. The issue is fixed by making nova_metadata_subnet configurable.
Drop all Qpid support, it was removed from Oslo in Mitaka.
Removed deprecated (for at least one cycle) options from agents:
use_namespaces option from l3/dhcp/lbaas agent
allow_automatic_l3agent_failover from l3 agent
