Dear StarlingX team When I create openstack as below. controller-0:~$ openstack network create --project ${ADMINID} --provider-network-type=flat --provider-physical-network=phy-flat netflat Error while executing command: BadRequestException: 400, Invalid input for operation: Flat provider networks are disabled. I get "Flat provider networks are disabled" message, so I check neutron server pod log message.
