Raman Budny db02bbf107 Fixes ovs-vsctl add port issue
Setup of OVS may fail, if ports that are added,
are already exist. Add "--may-exist" directive to OVS
add-port command to prevent this behaviour.

# the host (with no remote connectivity), and no physical resources
# will be available for the allocation of provider networks.
# To disable tunnels (GRE or VXLAN) for tenant networks,
# set to False in ``local.conf``.
# GRE tunnels are only supported by the openvswitch.

# tunnel IDs from which tenant networks are allocated. Can be
# overriden in ``localrc`` in necesssary.
TENANT_TUNNEL_RANGES=${TENANT_TUNNEL_RANGES:-1:1000}
# To use VLANs for tenant networks, set to True in localrc. VLANs
# are supported by the ML2 plugins, requiring additional configuration
# described below.
ENABLE_TENANT_VLANS=${ENABLE_TENANT_VLANS:-False}
# If using VLANs for tenant networks, set in ``localrc`` to specify
# the range of VLAN VIDs from which tenant networks are
# allocated. An external network switch must be configured to
# trunk these VLANs between hosts for multi-host connectivity.
#
# Example: ``TENANT_VLAN_RANGE=1000:1999``
TENANT_VLAN_RANGE=${TENANT_VLAN_RANGE:-}
# If using VLANs for tenant networks, or if using flat or VLAN
# provider networks, set in ``localrc`` to the name of the physical
# network, and also configure ``OVS_PHYSICAL_BRIDGE`` for the
# openvswitch agent or ``LB_PHYSICAL_INTERFACE`` for the linuxbridge
# agent, as described below.
#
# Example: ``PHYSICAL_NETWORK=default``

# With the openvswitch agent, if using VLANs for tenant networks,
# or if using flat or VLAN provider networks, set in ``localrc`` to
# the name of the OVS bridge to use for the physical network. The
# bridge will be created if it does not already exist, but a
# physical interface must be manually added to the bridge as a
# port for external connectivity.

# Example: ``OVS_PHYSICAL_BRIDGE=br-eth1``

# With the linuxbridge agent, if using VLANs for tenant networks,

# Example: ``LB_PHYSICAL_INTERFACE=eth1``

# When Neutron tunnels are enabled it is needed to specify the
# IP address of the end point in the local server. This IP is set

# This variable can be used to specify a different end point IP address
# Example: ``TUNNEL_ENDPOINT_IP=1.1.1.1``
TUNNEL_ENDPOINT_IP=${TUNNEL_ENDPOINT_IP:-$HOST_IP}
# With the openvswitch plugin, set to True in ``localrc`` to enable
# provider GRE tunnels when ``ENABLE_TENANT_TUNNELS`` is False.
