Description Eduardo Olivares 2021-04-14 11:03:17 UTC

Description of problem:
tempest test test_two_vms_fips fails on OSP16.2 jobs with RHOS-16.2-RHEL-8-20210409.n.0. This test passed with previous builds.
https://rhos-ci-jenkins.lab.eng.tlv2.redhat.com/view/DFG/view/network/view/networking-ovn/job/DFG-network-networking-ovn-16.2_director-rhel-virthost-3cont_2comp-ipv4-geneve-non_dvr/lastCompletedBuild/testReport/neutron_tempest_plugin.scenario.admin.test_floatingip/FloatingIpTestCasesAdmin/test_two_vms_fips_id_6bba729b_3fb6_494b_9e1e_82bbd89a1045_/


The test obtains the hypervisor hostnames via nova API:
GET http://10.0.0.131:8774/v2.1/os-hypervisors
...
        Body: b'{"hypervisors": [{"id": 2, "hypervisor_hostname": "compute-0.novalocal", "state": "up", "status": "enabled"}, {"id": 5, "hypervisor_hostname": "compute-1.novalocal", "state": "up", "status": "enabled"}]}'

And then tries to create a server with AZ=nova:compute-0.novalocal, but the server creation fails:
No valid host was found. No such host - host: compute-0.novalocal


I have run the test on 16.1 and the GET /os-hypervisors request is answered with values compute-X.redhat.local, which are the correct ones.

I am setting severity to high because it affects test automation.


Version-Release number of selected component (if applicable):
RHOS-16.2-RHEL-8-20210409.n.0

How reproducible:
100%

Steps to Reproduce:
1. run the command 'openstack hypervisor list'
2. or run the tempest test test_two_vms_fips
