Description

Observation

See #134282-1

There is something wrong with multimachine network when tests are run across different workers. If is multimachine job forced to run on same worker, it is fine.

There are fails in core group: https://openqa.suse.de/tests/11843205#next_previous
Kernel group: https://openqa.suse.de/tests/11846943#next_previous
HPC: https://openqa.suse.de/tests/11845897#next_previous

The scenario is https://openqa.suse.de/tests/latest?arch=x86_64&distri=sle&flavor=Server-DVD-Updates&machine=64bit&test=ovs-client&version=15-SP5

Acceptance criteria

  • AC1: The "ovs-client+ovs-server" test scenario passes consistently when running on multiple OSD workers with "tap" class

Suggestions

Out of scope

  • Anything that already fails when the multi-machine cluster runs on a single physical host
  • #135035 "Pin multimachine jobs to a single worker"
  • Any other test than "ovs-client+server"
  • Try to minimize the reproducer, e.g. skip test modules in openQA -> #135818

Workaround

Pin to a single physical machine
