 ovs_quantum_plugin.ini:

For information about the Open vSwitch plugin configurations, see http://wiki.openstack.org/ConfigureOpenvswitch.

Table B.10. Database Access by Plugin
Configuration option=Default value (Type) Description
sql_connection=sqlite://

(StrOpt) The details of the database connection. For example mysql://root:nova@127.0.0.1:3306/ovs_quantum. Replace 127.0.0.1 above with the IP address of the database used by the main quantum server. (Leave it as is if the database runs on this host.).

[Note]Note

This line must be changed to ensure that the database values are persistent. The sqlite is used for testing.

sql_max_retries=10 (IntOpt) Database re-connection retry times. This is in the event connectivity is lost with the database. -1 implies an infinite retry count.
reconnect_interval=2 (IntOpt) Database reconnection interval in seconds - in event connectivity is lost.

OVS Options (This is in the section OVS)

This section deals with the specific OVS options common to the plugin and agent.

Table B.11. OVS Options Common to Plugin and Agent
Configuration option=Default value (Type) Description
network_vlan_ranges=default:2000:3999 (ListOpt) Comma-separated list of  <physical_network>:<vlan_min>:<vlan_max> tuples enumerating ranges of VLAN IDs on named physical networks that are available for allocation.
tunnel_id_ranges= (ListOpt) Comma-separated list of <tun_min>:<tun_max> tuples enumerating ranges of GRE tunnel IDs that are available for allocation.
integration_bridge=br-int (StrOpt) This is the name of the OVS integration bridge. There is one per hypervisor. The integration bridge acts as a virtual "patch port". All VM VIFs are attached to this bridge and then "patched" according to their network connectivity. Do not change this parameter unless you have a good reason to.
tunnel_bridge=br-tun (StrOpt) Specifies the name of the OVS tunnel bridge used by the agent for GRE tunnels. Only used if tunnel_id_ranges is not empty.
bridge_mappings=default:br-eth1 (ListOpt) Comma-separated list of <physical_network>:<bridge> tuples mapping physical network names to agent's node-specific OVS bridge names. Each bridge must exist, and should have physical network # interface configured as a port.
local_ip=10.0.0.3 (StrOpt) Set local-ip to be the local IP address of this hypervisor. This is used only when tunnel_id_ranges are used.
enable_tunneling=False (BoolOpt) A flag indicating if tunneling is supported. Not all systems that support Open vSwitch support its GRE tunneling feature, that is, it is not supported in the Linux kernel source tree. This applies to both the server and agent

(This is in the section AGENT)

Table B.12. Agent Options
Configuration option=Default value (Type) Description
rpc=True (BoolOpt) If this is True then the agent will communicate with the plugin via the OpenStack RPC (configured in quantum.conf). If this is False then the agent will poll the database for changes. In the event that this is False then please update the relevant database settings on the agent so that it is able to access the database.
polling_interval=2 (IntOpt) Agent's polling interval in seconds.
root_helper=sudo (StrOpt) This enables limiting commands that can be run. Please refer to rootwrap section for more details.
