Features

Devstack Configuration

# # Sample DevStack local.conf. # # This sample file is intended to be used for your typical DevStack environment # that’s running all of OpenStack on a single host. This can also be used as # the first host of a multi-host test environment. # # No changes to this sample configuration are required for this to work. #

# The DevStack plugin defaults to using the ovn branch from the official ovs # repo. You can optionally use a different one. For example, you may want to # use the latest patches in blp’s ovn branch: #OVN_REPO=https://github.com/blp/ovs-reviews.git #OVN_BRANCH=ovn

# Use Neutron instead of nova-network disable_service n-net enable_service q-svc

# Disable Neutron agents not used with OVN. disable_service q-agt disable_service q-l3 disable_service q-dhcp disable_service q-meta

# Horizon (the web UI) is enabled by default. You may want to disable # it here to speed up DevStack a bit. enable_service horizon #disable_service horizon

# Cinder (OpenStack Block Storage) is disabled by default to speed up # DevStack a bit. You may enable it here if you would like to use it. disable_service cinder c-sch c-api c-vol #enable_service cinder c-sch c-api c-vol

# How to connect to ovsdb-server hosting the OVN NB database. #OVN_NB_REMOTE=tcp:$SERVICE_HOST:6641

# How to connect to ovsdb-server hosting the OVN SB database. #OVN_SB_REMOTE=tcp:$SERVICE_HOST:6642

# A UUID to uniquely identify this system. If one is not specified, a random # one will be generated and saved in the file ‘ovn-uuid’ for re-use in future # DevStack runs. #OVN_UUID=

# If using the OVN native layer-3 service, choose a router scheduler to # manage the distribution of router gateways on hypervisors/chassis. # Default value is leastloaded. #OVN_L3_SCHEDULER=leastloaded

# Whether or not to build custom openvswitch kernel modules from the ovs git # tree. This is enabled by default. This is required unless your distro kernel # includes ovs+conntrack support. This support was first released in Linux 4.3, # and will likely be backported by some distros. #OVN_BUILD_MODULES=False

# If you want to enable a provider network instead of the default private # network after your DevStack environment installation, you must set # the Q_USE_PROVIDER_NETWORKING to True, and also give FIXED_RANGE, # NETWORK_GATEWAY and ALLOCATION_POOL option to the correct value that can # be used in your environment. Specifying Q_AGENT is needed to allow devstack # to run various “ip link set” and “ovs-vsctl” commands for the provider # network setup. #Q_AGENT=openvswitch #Q_USE_PROVIDER_NETWORKING=True #PHYSICAL_NETWORK=providernet #PROVIDER_NETWORK_TYPE=flat #PUBLIC_INTERFACE=<public interface> #OVS_PHYSICAL_BRIDGE=br-provider #PROVIDER_SUBNET_NAME=provider-subnet # use the following for IPv4 #IP_VERSION=4 #FIXED_RANGE=<CIDR for the Provider Network> #NETWORK_GATEWAY=<Provider Network Gateway> #ALLOCATION_POOL=<Provider Network Allocation Pool> # use the following for IPv4+IPv6 #IP_VERSION=4+6 #FIXED_RANGE=<CIDR for the Provider Network> #NETWORK_GATEWAY=<Provider Network Gateway> #ALLOCATION_POOL=<Provider Network Allocation Pool> # IPV6_PROVIDER_FIXED_RANGE=<v6 CDIR for the Provider Network> # IPV6_PROVIDER_NETWORK_GATEWAY=<v6 Gateway for the Provider Network>

# If you wish to use the provider network for public access to the cloud, # set the following #Q_USE_PROVIDERNET_FOR_PUBLIC=True #PUBLIC_NETWORK_NAME=<Provider network name> #PUBLIC_NETWORK_GATEWAY=<Provider network gateway> #PUBLIC_PHYSICAL_NETWORK=<Provider network name> #IP_VERSION=4 #PUBLIC_SUBNET_NAME=<provider subnet name> #Q_FLOATING_ALLOCATION_POOL=<Provider Network Allocation Pool> #FLOATING_RANGE=<CIDR for the Provider Network>

# NOTE: DO NOT MOVE THESE SECTIONS FROM THE END OF THIS FILE # IF YOU DO, THEY WON’T WORK!!!!! #

# Enable Nova automatic host discovery for cell every 2 seconds # Only needed in case of multinode devstack, as otherwise there will be issues # when the 2nd compute node goes online. discover_hosts_in_cells_interval=2

Neutron metadata_agent.ini

The following configuration options in /etc/neutron/metadata_agent.ini are required when OVN is enabled in OpenStack neutron.

...

[ovs] # # From networking_ovn.metadata.agent #

# The connection string for the native OVSDB backend. # Use tcp:IP:PORT for TCP connection. # Use unix:FILE for unix domain socket connection. (string value) #ovsdb_connection = unix:/usr/local/var/run/openvswitch/db.sock

# Timeout in seconds for the OVSDB connection transaction (integer value) #ovsdb_connection_timeout = 180

[ovn] ovn_sb_connection = tcp:<controller-ip>:<port>

Neutron neutron.conf

The following configuration changes are required in /etc/neutron/neutron.conf

[DEFAULT] service_plugins = networking_ovn.l3.l3_ovn.OVNL3RouterPlugin

Neutron ml2_conf.ini

The following configuration changes are required in /etc/neutron/plugins/ml2/ml2_conf.ini

[ml2] mechanism_drivers = ovn,logger

[ovn] ovn_metadata_enabled = True ovn_l3_scheduler = leastloaded neutron_sync_mode = log ovn_sb_connection = tcp:<controller-ip>:<port> ovn_nb_connection = tcp:<controller-ip>:<port>
