+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.
