It is also possible to use nova-manage to create a network that refers to an existing Quantum network. The ''uuid'' flag passes an existing Quantum Network UUID to nova-manage, meaning that Quantum Manager does not need to contact the Quantum service to create a network. Instead the Quantum Manager will just create a corresponding IPAM subnet, and then create and delete ports on the network when VMs are created/deleted. For example:
nova-manage network create --label=public --fixed_range_v4=8.8.8.0/24 --priority=0 --uuid=0a649eca-3764-417c-91a7-eb51291d4bb9
