# lib/quantum
# functions - funstions specific to quantum
# Dependencies:
# ``functions`` file
# ``DEST`` must be defined
# ``stack.sh`` calls the entry points in this order:

# install_quantum_agent_packages
# install_quantum_third_party
# setup_quantum
# setup_quantumclient
# configure_quantum

# ``unstack.sh`` calls the entry points in this order:

# stop_quantum
# Functions in lib/quantum are classified into the following categories:
#
# - entry points (called from stack.sh or unstack.sh)
# - internal functions
# - quantum exercises
# - 3rd party programs
# Quantum Networking
# ------------------
# Make sure that quantum is enabled in ``ENABLED_SERVICES``. If you want
# to run Quantum on this host, make sure that q-svc is also in
# ``ENABLED_SERVICES``.
#
# If you're planning to use the Quantum openvswitch plugin, set
# ``Q_PLUGIN`` to "openvswitch" and make sure the q-agt service is enabled
# in ``ENABLED_SERVICES``. If you're planning to use the Quantum
# linuxbridge plugin, set ``Q_PLUGIN`` to "linuxbridge" and make sure the
# q-agt service is enabled in ``ENABLED_SERVICES``.
#
# See "Quantum Network Configuration" below for additional variables
# that must be set in localrc for connectivity across hosts with
# Quantum.
#
# With Quantum networking the NET_MAN variable is ignored.
# Save trace setting

# Provider Network Configurations
# --------------------------------
# The following variables control the Quantum openvswitch and
# linuxbridge plugins' allocation of tenant networks and
# availability of provider networks. If these are not configured
# in localrc, tenant networks will be local to the host (with no
# remote connectivity), and no physical resources will be
# available for the allocation of provider networks.
# To use GRE tunnels for tenant networks, set to True in
# localrc. GRE tunnels are only supported by the openvswitch
# plugin, and currently only on Ubuntu.
ENABLE_TENANT_TUNNELS=${ENABLE_TENANT_TUNNELS:-False}
# If using GRE tunnels for tenant networks, specify the range of
# tunnel IDs from which tenant networks are allocated. Can be
# overriden in localrc in necesssary.
TENANT_TUNNEL_RANGES=${TENANT_TUNNEL_RANGE:-1:1000}
# To use VLANs for tenant networks, set to True in localrc. VLANs
# are supported by the openvswitch and linuxbridge plugins, each
# 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``
PHYSICAL_NETWORK=${PHYSICAL_NETWORK:-}
# With the openvswitch plugin, if using VLANs for tenant networks,
# or if using flat or VLAN provider networks, set in localrc to
# the name of the OVS bridge to use for the physical network. The
# bridge will be created if it does not already exist, but a
# physical interface must be manually added to the bridge as a
# port for external connectivity.
#
# Example: ``OVS_PHYSICAL_BRIDGE=br-eth1``
OVS_PHYSICAL_BRIDGE=${OVS_PHYSICAL_BRIDGE:-}
# With the linuxbridge plugin, if using VLANs for tenant networks,
# or if using flat or VLAN provider networks, set in localrc to
# the name of the network interface to use for the physical
# network.
#
# Example: ``LB_PHYSICAL_INTERFACE=eth1``
LB_PHYSICAL_INTERFACE=${LB_PHYSICAL_INTERFACE:-}
# With the openvswitch plugin, set to True in localrc to enable
# provider GRE tunnels when ``ENABLE_TENANT_TUNNELS`` is False.
#
# Example: ``OVS_ENABLE_TUNNELING=True``
