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 at 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.
