This message is from keystoneauth. My guess is that you misconfigured the [keystone_authtoken] section in neutron.conf.

Hi @Bernd Bausch

My neutron.conf in Controller node [keystone_authtoken]

auth_uri = http://controller:5000

auth_url = http://controller:35357

memcached_servers = controller:11211

auth_type = password

project_domain_name = default

user_domain_name = default

project_name = service

username = neutron

password = root


Also when I am restarting my Keystone service I am getting

root@controller:~# service keystone restart

Failed to restart keystone.service: Unit keystone.service not found.

root@controller:~# systemctl status openstack-keystone

● openstack-keystone.service Loaded: not-found (Reason: No such file or directory) Active: inactive (dead)

Also I could not see keystone.log file under /var/log/keystone. What could be the issue ??

Keystone normally runs under a web server, not as a standalone systemd service. Check if it runs.

The install guide doesn't use auth_uri; not sure if that's significant. Does controller resolve to an IP address?

2.following this for neutron.conf here under [keystone_authtoken] it uses "auth_uri" (

3.I am able to ping from compute node with controller hostname. But my nslookup fails for controller

Is it making the issue ??
