Currently, neutron tunnel endpoints must be IPv4 addresses, i.e. $HOST_IP, although IPv6 endpoints are supported by most drivers. Create a TUNNEL_IP_VERSION variable to choose which host IP to use, either HOST_IP or HOST_IPV6, and configure it in the OVS and Linuxbridge agent driver files. The default is still IPv4, but it can be over-ridden by specifying TUNNEL_ENDPOINT_IP accordingly. This behaves similar to the SERVICE_IP_VERSION option, which can either be set to 4 or 6, but not 4+6 - the tunnel overhead should be consistent on all systems in order not to have MTU issues. Must set the ML2 overlay_ip_version config option to match else agent tunnel sync RPC will not work. Must set the OVN external_ids:ovn-encap-ip config option to the correct address. Updated 'devstack-ipv6-only' job definition and verification role that will set all services and tunnels to use IPv6 addresses.

Verify all addresses in IPv6-only deployments
This role needs to be invoked from a playbook that runs tests. This role verifies the IPv6 settings on the devstack side and that devstack deploys with all addresses being IPv6. This role is invoked before tests are run so that if there is any missing IPv6 setting, deployments can fail the job early.
