Restart of single controller (non-HA) leads to "No valid hosts found" error

[Vladimir Khlyunev]

Swarm test failed: https://product-ci.infra.mirantis.net/job/9.0.system_test.ubuntu.thread_1/82/testReport/%28root%29/ha_one_controller_neutron_warm_restart/ha_one_controller_neutron_warm_restart/

ISO 213

Steps to reproduce:
1. Create cluster
2. Add 1 node with controller role
3. Add 1 node with compute role
4. Deploy the cluster
5. Run network verification
6. Run OSTF
7. Warm restart of the controller
8. Wait for Galera is up
9. Run network verification
10. Run OSTF << fail here

Expected result:
All OSTF tests passed

Actual result:
4 tests which launch an instance fails.
Error from nova-conductor log:

Looks like problem with neutron:
 Build of instance a18f291d-f0e0-47da-a70c-4b043d57759f was re-scheduled: Binding failed for port 2556996b-04cb-47d0-adb5-582d4ed9b413, please check neutron logs for more information

Under investigation.

We should add sanity tests for neutron agent availability.
Currently we are checking only if nova services are online.

We need to check also neutron agents (neutron agent-list)

It is possible that test tries to spawn VM when neutron is not available yet.

[Matthew Mosesohn (raytrac3r)]

+1 sanity tests for neutron agent-list and also we can do cinder service-list.

[Andrey Sledzinskiy (asledzinskiy)]

Move to won't fix for 9.0, we won't be able to provide new OSTF test before HCF
