I got this error trying to launch a cirros instance in Openstack. "Error: Failed to perform requested operation on instance "cirros", the instance has an error status: Please try again later [Error: Host '' is not mapped to any cell]".

I have queens-compute-1 and queens-compute-2 as host aggregates in nova availability zone.

What is the issue?

The issue is that this node (and perhaps the other one as well) is not in a cell. If you installed the cloud manually, see these instructions. If not, something went wrong during your installation, and it depends on the deployment method how to troubleshoot this.

Hi Bernd,

Thank you for the instructions in the link. All I had to do was to execute "su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova" on the Cluster Controller and solved the problem. You can close the case.
