Hi @ibm-adarsh. Thanks for your PR. I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with Tip We noticed you've done this a few times!

Remove the separate ocp-heavy-build-ovn-remote-libvirt-s390x periodic jobs
from openshift/multiarch nightly configs (4.12–4.16) and regenerate Prow
periodics.
Delete the libvirt conf logic that excluded bandwidth-heavy build/image tests
from conformance-parallel on s390x (≤4.16) or materialized them as a dedicated
test list for heavy-build jobs.
Remove the heavy-build TEST_TYPE branch and heavy_build helper from the
libvirt e2e test step, since that job type is no longer used.
Rationale: Z conformance parallel jobs should run the full openshift/
conformance/parallel suite without a split heavy-build lane.
Summary
This PR removes the separate heavy-build test job for IBM Z (s390x) systems from OpenShift's CI infrastructure and consolidates the test workload into the standard conformance-parallel suite.
Changes
Multiarch CI Configuration (Versions 4.12–4.16)
Removed the
ocp-heavy-build-ovn-remote-libvirt-s390xperiodic job entries from nightly multiarch CI configurations for OpenShift versions 4.12, 4.13, 4.14, 4.15, and 4.16. This job type previously ran bandwidth-heavy build and image tests separately from the main conformance suite on s390x architectures.Libvirt E2E Test Configuration
Deleted conditional logic in the libvirt configuration step (
openshift-e2e-libvirt-conf-commands.sh) that excluded certain tests on s390x systems when running conformance-parallel tests. This logic previously maintained a separate "yellow zone" exclusion list for bandwidth-heavy tests on z/ppc64le architectures.Libvirt Test Runner
Removed the
heavy_build()function and its correspondingheavy-buildcase branch from the libvirt E2E test runner script (openshift-e2e-libvirt-test-commands.sh). TheTEST_TYPEenvironment variable no longer recognizes theheavy-buildvalue, as this job type is being deprecated.Impact
s390x conformance jobs will now execute the complete openshift/conformance/parallel test suite without bandwidth-heavy tests being excluded or materialized as a separate periodic job. This simplifies the CI infrastructure for IBM Z systems while maintaining full test coverage.
