    default: openstacklocal
    description: Domain to use for building the hostnames.
  NeutronCorePlugin:
    default: 'ml2'

        The core plugin for Neutron. The value should be the entrypoint to be loaded
        from neutron.core_plugins namespace.
    type: string

    description: |
        MTU of the underlying physical network. Neutron uses this value to
        calculate MTU for all virtual network components. For flat and VLAN
        networks, neutron uses this value without modification. For overlay
        networks such as VXLAN, neutron automatically subtracts the overlay
        protocol overhead from this value.
