+      Base Tempest IPv6 job. This job is derived from 'devstack-ipv6'
+      which set the IPv6-only setting for OpenStack services. As part of
+      run phase, this job will verify the IPv6 setting and check the services
+      endpoints and listen addresses are IPv6. Basically it will run the script
+      ./tool/verify-ipv6-only-deployments.sh
+
+      Child jobs of this job can run their own set of tests and can
+      add post-run playebooks to extend the IPv6 verification specific
+      to their deployed services.
+      Check the wiki page for more details about project jobs setup

+Verify the IPv6-only deployments

+This role needs to be invoked from a playbook that

+devstack side and devstack deploy services on IPv6.
+This role is invoked before tests are run so that
+if any missing IPv6 setting or deployments can fail
+the job early.
