Creating specific OVS bridges for physical networks
---------------------------------------------------
When using the Open vSwitch ML2 mechanism driver, it is possible to
have multiple Open vSwitch bridges meant for physical networking be
automatically created by setting the ``OVS_BRIDGE_MAPPINGS`` to a list of
physical network to bridge name associations with the following syntax:
::
OVS_BRIDGE_MAPPINGS=net1name:bridge1name,net2name:bridge2name,<...>
Also, ``OVS_BRIDGE_MAPPINGS`` has precedence over ``PHYSICAL_NETWORK`` and
``OVS_PHYSICAL_BRIDGE``, meaning that if the former is set, the latter
ones will be ignored. When ``OVS_BRIDGE_MAPPINGS`` is not set, the other
variables will still be evaluated.
