Kyle,
Thanks for the response. Here is the output to the file. I also posted to a.o.o.
[ovs]
# (StrOpt) Type of network to allocate for tenant networks. The
# default value 'local' is useful only for single-box testing and
# provides no connectivity between hosts. You MUST either change this
# to 'vlan' and configure network_vlan_ranges below or change this to
# 'gre' or 'vxlan' and configure tunnel_id_ranges below in order for
# tenant networks to provide connectivity between hosts. Set to 'none'
# to disable creation of tenant networks.
#
tenant_network_type = gre
tunnel_id_ranges = 1:1000
enable_tunneling = True
# Example: tenant_network_type = gre
# Example: tenant_network_type = vxlan
# (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. All physical networks listed are available for flat and
# VLAN provider network creation. Specified ranges of VLAN IDs are
# available for tenant network allocation if tenant_network_type is
# 'vlan'. If empty, only gre, vxlan and local networks may be created.
#
# network_vlan_ranges =
# Example: network_vlan_ranges = physnet1:1000:2999
# (BoolOpt) Set to True in the server and the agents to enable support
# for GRE or VXLAN networks. Requires kernel support for OVS patch ports and
# GRE or VXLAN tunneling.
#
# WARNING: This option will be deprecated in the Icehouse release, at which
# point setting tunnel_type below will be required to enable
# tunneling.
#
# enable_tunneling = False
# (StrOpt) The type of tunnel network, if any, supported by the plugin. If
# this is set, it will cause tunneling to be enabled. If this is not set and
# the option enable_tunneling is set, this will default to 'gre'.
#
# tunnel_type =
# Example: tunnel_type = gre
# Example: tunnel_type = vxlan
# (ListOpt) Comma-separated list of <tun_min>:<tun_max> tuples

# Do not change this parameter unless you have a good reason to.
# This is the name of the OVS integration bridge. There is one per hypervisor.
# The integration bridge acts as a virtual "patch bay". All VM VIFs are
# attached to this bridge and then "patched" according to their network
# connectivity.

# integration_bridge = br-int
# Only used for the agent if tunnel_id_ranges (above) is not empty for
# the server. In most cases, the default value should be fine.

# Uncomment this line for the agent if tunnel_id_ranges (above) is not
# empty for the server. Set local-ip to be the local IP address of
# this hypervisor.
#
# local_ip =
# (ListOpt) Comma-separated list of <physical_network>:<bridge> tuples
# mapping physical network names to the agent's node-specific OVS
# bridge names to be used for flat and VLAN networks. The length of
# bridge names should be no more than 11. Each bridge must
# exist, and should have a physical network interface configured as a
# port. All physical networks listed in network_vlan_ranges on the
# server should have mappings to appropriate bridges on each agent.
#
# bridge_mappings =
# Example: bridge_mappings = physnet1:br-eth1
[agent]
# Agent's polling interval in seconds
# polling_interval = 2
# (ListOpt) The types of tenant network tunnels supported by the agent.
# Setting this will enable tunneling support in the agent. This can be set to
# either 'gre' or 'vxlan'. If this is unset, it will default to [] and
# disable tunneling support in the agent. When running the agent with the OVS
# plugin, this value must be the same as "tunnel_type" in the "[ovs]" section.
# When running the agent with ML2, you can specify as many values here as
# your compute hosts supports.
#
# tunnel_types =
# Example: tunnel_types = gre
# Example: tunnel_types = vxlan
# Example: tunnel_types = vxlan, gre
# (IntOpt) The port number to utilize if tunnel_types includes 'vxlan'. By
# default, this will make use of the Open vSwitch default value of '4789' if
# not specified.
#
# vxlan_udp_port =
# Example: vxlan_udp_port = 8472
# (IntOpt) This is the MTU size of veth interfaces.
# Do not change unless you have a good reason to.
# The default MTU size of veth interfaces is 1500.
# veth_mtu =
# Example: veth_mtu = 1504
# (BoolOpt) Flag to enable l2-population extension. This option should only be
# used in conjunction with ml2 plugin and l2population mechanism driver. It'll
# enable plugin to populate remote ports macs and IPs (using fdb_add/remove
# RPC calbbacks instead of tunnel_sync/update) on OVS agents in order to
# optimize tunnel management.

I just replied to this on the ask site [1], can you please have
a look there and respond?
Thanks!
