Hi Trey, Have you defined a record in your /etc/hosts for "controller", as according to the error service simply can not resolve this hostname to an IP address. Also I can suggest trying out one of the following OpenStack deployment tools: https://docs.openstack.org/zed/deploy/index.html Most of them have All-In-One guides that can spawn an opestack sandbox to play with. вт, 11 апр. 2023 г., 00:21 Trey Fleishman <nfleishman@student.ccaeagles.org

Hello all, Recently I tried installing Openstack via this <https://docs.openstack.org/install-guide/openstack-services.html> guide. Upon completion of all the steps including the dashboard step, I was greeted with this error inside the nova_schedular.log file, after I tried creating an instance.

2103 ERROR oslo.messaging._drivers.impl_rabbit Connection failed: failed to resolve broker hostname: OSError: failed to resolve broker hostname

When I try to create an instance it hangs in the "scheduling" state and throws this error. I have not configured anything in the "oslo.messaging" section of the Nova config file. I believe that under the [default] section this is what's causing the issue, but the password and hostname are fine.

transport_url = rabbit://openstack:BnE9LLfCtjdPvpEnZUnPytSyrfUxE8th@controller

Thanks!
