Description Eduardo Olivares 2021-10-20 10:52:05 UTC

Description of problem:
This bug is similar to BZ1949454
The affected test is the one mentioned in the comment 1 of that bug: test_igmp_snooping_ext_network_and_unsubscribe

In this case, the issue is reproduced by the OSP16.1 OVN update job:
1) RHOS-16.1-RHEL-8-20210903.n.0 is installed - python3-networking-ovn-7.3.1-1.20210409093428.4e24f4c.el8ost.noarch.rpm -> BZ1949454 was not resolved in this RPM, so the tests fails as expected
2) OSP is updated to RHOS-16.1-RHEL-8-20211007.n.1 - python3-networking-ovn-7.3.1-1.20210714143309.el8ost.noarch.rpm -> BZ1949454 was fixed in a previous version of this RPM, but, unexpectedly the test fails because two IGMP messages are received (only one was expected)

Link to the test results after the update: https://rhos-ci-jenkins.lab.eng.tlv2.redhat.com/job/DFG-network-networking-ovn-update-16.1_director-rhel-virthost-3cont_2comp_2net-ipv4-geneve-composable/83//artifact/tempest-results/tempest-results-neutron.2.html


Furthermore, this test passes on other 16.1 jobs using RHOS-16.1-RHEL-8-20211007.n.1 without an OSP update. For example:
https://rhos-ci-jenkins.lab.eng.tlv2.redhat.com/job/DFG-network-networking-ovn-16.1_director-rhel-virthost-3cont_2comp-ipv4-geneve-gate-ovn/10//artifact/tempest-results/tempest-results-neutron.1.html





Version-Release number of selected component (if applicable):
RHOS-16.1-RHEL-8-20211007.n.1

How reproducible:
For the moment, only reproduced once by the update job:
https://rhos-ci-jenkins.lab.eng.tlv2.redhat.com/job/DFG-network-networking-ovn-update-16.1_director-rhel-virthost-3cont_2comp_2net-ipv4-geneve-composable/83/
