Abhishek: In addition to the localrc settings as Elena suggests, try sourcing credentials for user 'admin' using the devstack/openrc script, e.g.: source ~/devstack/openrc admin before executing neutron commands. Later, if you want to e.g. launch a VM as user/tenant 'demo', you would source credentials as: source ~/devstack/openrc demo Good luck!
