[OVN] "test_agent_show" failing, chassis not found

[Rodolfo Alonso]

"test_agent_show" for OVN backend is failing.

Error: https://storage.gra.cloud.ovh.net/v1/AUTH_dcaab5e32b234d56b626f72581e3644c/zuul_opendev_logs_5d8/753053/3/check/neutron-functional-with-uwsgi/5d8606d/testr_results.html

I think I found the culprit: https://review.opendev.org/#/c/752797/

I'll push a patch for this.

My bad, c#1 is not for this bug.

Logstash query for this:
http://logstash.openstack.org/#dashboard/file/logstash.json?query=message%3A%5C%22Cannot%20find%20Chassis%20with%20uuid%5C%22

[Rodolfo Alonso (rodolfo-alonso-hernandez)]

Hello:

So far, this is what I found: the chassis created by the test case does not match with the chassis searched. E.g.: in [1], the chassis created is

"Chassis":{"33bd8d74-76ad-4619-82a4-21d7648457d2":{"insert":{"name":"a44e691a-ecde-4021-b10f-76c4144d2764","hostname":"test-host","external_ids":["map",[["ovn-bridge-mappings",""]]],"encaps":["uuid","d5d827db-c394-4167-98b7-dbee5be492ca"]}}}

But the chassis searched is [2] 2fb76247-2ccd-429e-8aac-fce9fc9b35b6.

I don't see where this chassis UUID is generated and why.

Regards.

    Do not update agents "alive" state in TestAgentApi

    During the execution of FT TestAgentApi, we should not update the
    chassis agents "alive" state; during the FT execution, some of the
    agents returned by "agents_from_chassis" do not really exist (not
    relevant for the test case).
