Hello Everyone, I was testing a new OpenStack deployment, and was unable to launch instances due to this bug: https://bugs.launchpad.net/nova/+bug/1508230 I did a sudo apt-get upgrade on my controller and compute nodes. After the upgrade, Horizon started returning "Error: Unable to retrieve instance list." I did some digging around in the logs, and found this in nova-api.log: 016-02-05 15:51:33.145 21672 ERROR nova.api.openstack ConnectionRefused: Unable to establish connection to http://127.0.0.1:9696/v2.0/ports.json?device_id=ed51aca4-f945-4c7d-aa12-6b8d4f4da562 I did some grepping in /etc/nova and /etc/neutron for any mention of the address, since I was previously not using that Address for Neutron. No results. I ran "openstack endpoint list" and found that nothing had changed in my neutron endpoints: | 1bb91742f11f4f84903b6074867f131a | RegionOne | neutron | network | True | admin | http://192.168.0.150:9696 | | a4a7577303af43f98688cfc15e283bcc | RegionOne | neutron | network | True | internal | http://192.168.0.150:9696 | | bea5f00aa2ad4e5fa865e17b9e5268cb | RegionOne | neutron | network | True | public | http://<MY SECRET PUBLIC IP ADDRESS>:9696 | So, what gives? Why did nova-api suddenly start looking for neutron at the loopback address? How can I fix this? Thanks in advance for any help. -------------- next part -------------- An HTML attachment was scrubbed...
