[Bug 1687345] [NEW] NoValidHosts (resource_providers table is empty)

 

Public bug reported:

Kolla (stable/ocata, 4.0.2) was deployed as multinode (virtualized on
Openstack/KVM) environment, but fails to provision instances.

First symptom was 
... Starting with 0 host(s) get_filtered_objects /var/lib/kolla/venv/local/lib/python2.7/site-packages/nova/filters.py:70
... Filtering removed all hosts for the request with instance ID '...'. Filter results: ['RetryFilter: (start: 0, end: 0)']
... NoValidHost: No valid host was found. There are not enough hosts available.

Placement API does not return any resource provider

GET /resource_providers
{
  "resource_providers": []
}

Following the request flow, I reach a point where I confirmed the
resource_providers table is empty.

root@pod09-control01:~# docker exec -ti mariadb mysql -unova_api -p ... nova_api
...
MariaDB [nova_api]> select * from resource_providers;
Empty set (0.00 sec)

The only unusual thing, is that initially I deployed with QEMU, as
compute node was going to be virtualized over KVM. Later, I enabled KVM
nested virtualization in the host, so, now compute is virtualization
capable.

Any ideas, how can I make resource providers work?
