[Rdo-list] how to add repository for the cerfitication test suite

Dear all, I'm engaged in redhat openstack test. When I read the user guide, it says to enable the test suite repository with below commands: subscription-manager repos --enable=rhel-7-server-openstack-5.0-cts-rpms Seems this does not work on my system: [root@redhat1 ~]# subscription-manager repos --enable=rhel-7-server-openstack-5.0-cts-rpms Error: rhel-7-server-openstack-5.0-cts-rpms is not a valid repo ID. Use --list option to see valid repos. [root@redhat1 ~]# There's no cts in the repository [root@redhat1 yum.repos.d]# grep -i cts redhat.repo [root@redhat1 yum.repos.d]# Could you please tell me how to add the repository? Thanks and regards Sam
