Are you sure you're stopping the nova-compute service before deleting the actual service record via the API?
https://developer.openstack.org/api-ref/compute/#delete-compute-service Otherwise the ResourceTracker in the compute process will recreate the compute node. The Service.destroy is called from the API here: https://github.com/openstack/nova/blob/d87852ae6a1987b6faa3cb5851f9758b47ef4636/nova/api/openstack/compute/services.py#L251 Which eventually calls the DB API to delete the associated compute node record: https://github.com/openstack/nova/blob/d87852ae6a1987b6faa3cb5851f9758b47ef4636/nova/db/sqlalchemy/api.py#L404 ** Changed in: nova Status: New => Invalid -- You received this bug notification because you are a member of Yahoo!
