Hi all: I must have done something wrong in the installation of Openstack Placement. I have been through the steps to install placement multiple times now. I am using the Caracal release. I am on CentOS Stream 9. Everything seems to be installed correctly. Indeed, the upgrade check returns no errors: [root@cloud ~]# placement-status upgrade check +-------------------------------------------+ | Upgrade Check Results | +-------------------------------------------+ | Check: Missing Root Provider IDs | | Result: Success | | Details: None | +-------------------------------------------+ | Check: Incomplete Consumers | | Result: Success | | Details: None | +-------------------------------------------+ | Check: Policy File JSON to YAML Migration | | Result: Success | | Details: None | +-------------------------------------------+ [root@cloud ~]# Verifying operation however returns nothing: [root@cloud ~]# openstack --os-placement-api-version 1.2 resource class list Could not load 'volume_backup_unset': module 'openstackclient.volume.v2.volume_backup' has no attribute 'UnsetVolumeBackup' Expecting value: line 1 column 1 (char 0) The placement service has been defined (the host name is "cloud", not "controller").

Yes, I have restarted httpd. How do I know that Placement isn't working? Nova Conductor and Nova Scheduler can't connect to it (firewall is off and iptables rules are flushed) and therefore won't start properly. I can telnet to port 8778 yet the Nova services claim it can't connect. Thank you for your help! Ron Gage
