We already discussed about that, and a change was also provided https://review.openstack.org/#/c/420079/ but if you see the status of that change, it was abandoned.
If you look at the reason why it was abandoned, it is because we made a consensus on leaving simple_cells_setup() as much simple and opiniated as possible and rather provide a step-by-step experience for operators deploying CellsV2 that you can see described in https://docs.openstack.org/developer/nova/cells.html#first-time-setup ** Changed in: nova Status: New => Invalid -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1666029 Title: simple_cell_setup should not exist with 1 when there is no compute hosts Status in OpenStack Compute (nova): Invalid Bug description: When deploying ironic environment, even though nova-compute is running, but there will be no compute nodes until adding ironic nodes. And the user may not start nova-compute for some reason during fresh deployment. So stop return 1 when there is no compute hosts in simple_cell_setup.
