error : network_type_value 'flat' not supported while creating a new external network
HI everyone,
i installed Openstack juno all-in-one in a single VM using the RDO packstack. i configured the external bridge to meet the configuration of my environment then i wanted to create the external network from the begining so i deleted the default network and also the router.
when i tried to create a new external network i encounter the error :
create failed (client error): Invalid input for operation: network_type value 'flat' not supported.
the log of network server shows
