Inline comments:
In `@scripts/microshift-cleanup-data.sh`:
- Line 114: Update clean_processes to stop suppressing failures from systemctl
restart openvswitch.service: remove the unconditional success fallback so the
restart error propagates and cleanup fails when Open vSwitch cannot be
restarted.
In `@test/resources/systemd.resource`:
- Around line 93-94: Update the journald setup command near the existing printf
and systemctl restart operation so the complete shell expression, including
redirection and restart, executes with root privileges when SSHLibrary applies
sudo; wrap the expression in sh -c under sudo=True or split it into separate
privileged commands. Apply the same correction to the corresponding teardown
commands around the second journald configuration block.
In `@test/suites/configuration2/logging.robot`:
- Line 38: Update the journald setup and teardown around “Disable Journal Rate
Limiting” and “Enable Journal Rate Limiting” to preserve any pre-existing
disable-ratelimit.conf drop-in. Either back up and restore the original file or
track whether the suite created it, and only remove the drop-in during teardown
when it was created by this suite.

I'm not sure we need an extra message for this because we will then have to update the docs, etc.

I do not think this is acceptable. If we do not wait until the namespace is removed, the subsequent tests may fail because the namespace already exists.

The cleanup script stops ovsdb-server but leaves ovs-vswitchd running without its database. This stale OVS state prevents OVN from reinitializing when MicroShift is restarted, causing all pods to get stuck in FailedCreatePodSandBox. Stop openvswitch.service so the stale state is cleared. The next MicroShift start brings openvswitch back up via microshift.service's Wants and microshift-ovs-init.service's Requires, giving OVN a clean slate to reinitialize.

The .local TLD is reserved for mDNS (RFC 6762) and can cause DNS interference with OVN initialization on systems with Avahi or systemd-resolved, contributing to healthcheck timeouts after hostname changes.

The "Case Insensitive Log Levels" test fails on ARM when testing TraceAll because klog verbosity 10 generates ~144K journal messages, exceeding journald's default rate limit of 10K messages per 30 seconds. The suppressed messages include the startup config dump line that the test greps for, making the assertion impossible to satisfy. Instead of globally disabling rate limiting in all test VMs, scope the fix to the logging suite: disable rate limiting in suite setup and re-enable it in teardown.

The Remove Namespace keyword ran `oc delete namespace` with the default blocking wait, so a single `oc` process could exceed the 300s RF process timeout while resources and finalizers drained. On ARM with dual-stack, OVN reconciliation after a network config change saturates the CPU, making namespace garbage collection slow enough to trip this. The killed `oc` returned rc=1, which cascaded as a suite teardown failure and retroactively marked all passing tests as failed. Instead, request deletion with --wait=false and then poll until the namespace is actually gone. Each `oc get` poll is short (never hitting the process timeout), and we still wait for full removal so a subsequent test can reuse the namespace name without a "being deleted" collision.

Release scenarios running upgrade paths with LVMS workloads followed by full standard suites were hitting timeout limits under I/O contention on x86 (c5.metal, 4750 Mbps EBS) when many VMs boot and pull images in parallel. Increase greenboot healthcheck timeout from 600s to 1200s and robot framework timeout from 30m (CI-overridden to 45m) to 60m for release scenarios only.

GREENBOOT_TIMEOUT=1200 and TEST_EXECUTION_TIMEOUT=60m are now set centrally in ci_phase_boot_and_test.sh for all release scenarios. Remove the redundant per-scenario overrides. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> pre-commit.check-secrets: ENABLED

SSHLibrary's sudo=True prefixes with sudo, but shell redirection is interpreted by the non-root shell. Wrapping in bash -c ensures the entire expression runs as root.

openshift#7298 reduced release-scenario VM disks from 30GB to 20GB. That is safe for the lvms-standard/standard scenarios (they create a single 1Gi PVC), but the ginkgo scenario runs the full storage spec suite which requests several 1Gi PVCs concurrently. At 20GB the topolvm data VG only has ~420MiB free, so 7 storage specs fail with: ResourceExhausted ... no enough space left on VG: free=440401920, requested=1073741824 (arm-el10) and on x86 el10 the same undersized VM shows etcd ReadIndex latency and apiserver TLS-handshake flaps from I/O contention. Restore only this scenario to --vm_disksize 30; the other nine 20GB scenarios stay as-is since a single 1Gi PVC fits comfortably.

On a fresh/clean start the standard2 Log Scan test intermittently fails "Should Not Find Forbidden" with: pods cert-manager-cainjector-... is forbidden: error looking up service account cert-manager/cert-manager-cainjector: serviceaccount ... not found Investigation: the cainjector/controller/webhook Deployments and their ServiceAccounts are created dynamically by the cert-manager operator, not by MicroShift's static manifests. The kube-controller-manager ReplicaSet controller can briefly attempt to create a pod before its ServiceAccount is observed, logging this transient "forbidden" and retrying it away once the SA lands. The workloads become ready (MicroShift healthcheck passes), so this is a benign eventual-consistency startup race, not a MicroShift manifest-ordering bug — the ordering is the operator's, not ours. Add a scoped known-exceptions allowlist to the journalctl log-scan helper and register this single pattern, so genuine "forbidden" regressions still fail while this benign race is ignored.
