Hm, indeed rather strange to me. Do you see anything in the nova-scheduler.log? If you activated the discover_hosts_in_cells_interval = 300 it should query for new hosts every 5 minutes. Zitat von Pavlos Basaras <pbasaras@gmail.com>:

I'd probably delete the cell with UUID 1a0fde85-8906-46fb-b721-01a28c978439 and retry the discover_hosts with the right cell UUID: nova-manage cell_v2 delete_cell --cell_uuid 1a0fde85-8906-46fb-b721-01a28c978439 nova-manage cell_v2 discover_hosts --cell_uuid 1522c22f-64d4-4882-8ae8-ed0f9407407c Does that work?

Hello, maybe there is stg wrong with the installation. Let me clarify a few things. I have devstack deployed in a VM (pre-installed: keystone, glance, nova, placement, cinder, neutron, and horizon.) I can deploy machines successfully at the devstack controller space --everything seems to work fine. --> is seems to work fine with opensource mano as well I am trying to add another pc as a compute host to be able to deploy vms at this new compute host following ( https://docs.openstack.org/nova/queens/install/compute-install-ubuntu.html) Also attached the nova.conf file. The only major differences are: --the transport url for rabbitmq which i made according to the transport url of the controller, i.e., instead of rabbit://openstack:linux@controller i have rabbit://stackrabbit:linux@controller -- i replaced the ports with the service, e.g., instead using the 5000 port --> "http://controller/identity/v3" instead of "http://controller:5000/v3" please excuse (any) newbie questions all the best, Pavlos.

Did you change the transport_url only in the nova.conf of the new compute node? Or did you also change the rabbitmq configuration? The transport_url should match the actual rabbitmq config, of course, and it should be the same on every node. Does that match your cell setup? To compare run: control:~ # nova-manage cell_v2 list_cells --verbose Do you have a vhost configuration? (I'm not familiar with devstack) Here's an example of a "nova" vhost with respective permissions: control:~ # rabbitmqctl list_vhosts Listing vhosts / nova control:~ # rabbitmqctl list_permissions -p nova Listing permissions in vhost "nova" nova .* .* .* If there's a vhost it should be also reflected in the transport_url. Maybe you should share all of the above information here. Zitat von Pavlos Basaras <pbasaras@gmail.com>:

best, Pavlos.
The database connection doesn't look right, the compute node also needs access to the nova database (localhost is not reachable for another compute node) and usually with the nova user, not root, but that might be a devstack thing, I can't tell. The db settings in your nova.conf also seem wrong: [database] connection = sqlite:////var/lib/nova/nova.sqlite This should point to the nova database on the control node matching the one from 'nova-manage cell_v2 list_cells' command. I think there are lots of things not matching a multi-node setup, you'll need to fix that. As I said, I'm not familiar with devstack at all so I can't really tell exactly what needs to be done.
