parameters:
ServiceData:
default: {}
description: Dictionary packing service data

NeutronBridgeMappings:
description: >
The OVS logical->physical bridge mappings to use. See the Neutron
documentation for details. Defaults to mapping br-ex - the external
bridge on hosts - to a physical name 'datacentre' which can be used
to create provider networks (and we use this for the default floating
network) - if changing this either use different post-install network
scripts or be sure to keep 'datacentre' as a mapping network name.
