Learning: In the openshift-virtualization-tests repository, when responding to test execution plan requests from openshift-virtualization-qe-bot-3, do NOT use "REQUEST_CHANGES" review type if the PR author has already marked the PR as verified (e.g., with `/verified` command). Test execution plans are informational guides, not blocking requirements. Use COMMENT event for informational test plans, or only REQUEST_CHANGES if there are actual code issues that need to be addressed before merging.

Learning: In the openshift-virtualization-tests repository, unused fixture parameters in test methods (e.g., `bridge_on_one_node` in `tests/network/upgrade/test_upgrade_network.py`) that exist purely for pytest dependency ordering should not be flagged for removal, and no follow-up issues need to be opened for them. This is an intentional pattern, consistent with the analogous convention for fixture definitions in this codebase.

Learning: For PR `#1904` test execution, the critical validation point is test_connectivity_over_migration_between_localnet_vms which should fail gracefully on cloud clusters but pass on bare-metal/PSI clusters, representing the core nmstate conditional logic functionality.

Learning: In `tests/network/l2_bridge/nad_ref_change/test_nad_ref_change.py`, the negative test `test_non_migratable_vm_nad_change_not_applied` uses connectivity-only Expected assertions (not a rejection signal) because the NAD live-update feature does NOT expose a rejection/error signal for non-migratable VMs. The only verifiable outcome is that the VM remains connected to the original network with no connectivity to the target VLAN. Do not flag the absence of a rejection-signal assertion in this test as a defect.

Learning: In the RedHatQE/openshift-virtualization-tests repository, sanity checks validate that the cluster supports at least one IP family (IPv4 or IPv6) before SR-IOV tests run. Therefore, defensive guards checking for empty IP addresses in SR-IOV VM fixtures (like `sriov_vm` in tests/network/sriov/conftest.py) are not necessary—if neither `ipv4_supported_cluster` nor `ipv6_supported_cluster` is True, the cluster is considered broken and will fail sanity validation.

Learning: In `tests/network/localnet/test_ovs_bridge.py` and `tests/network/localnet/test_jumbo_frames.py`, predicates and assertions checking for a specific count or non-empty list of `filter_link_local_addresses(iface.ipAddresses)` results after `lookup_iface_status` are redundant. VMs in localnet tests are provisioned with explicit IPv4/IPv6 addresses via `ip_addresses_from_pool`, and session-scoped sanity checks guarantee at least one IP family is active. Do not suggest count-based or empty-guard predicates on `ipAddresses` in localnet OVS bridge or jumbo frame tests.

Learning: In the openshift-virtualization-tests repository, when determining smoke test impact for changes affecting py_config["os_login_param"], follow this verification methodology: (1) Find all smoke tests: `rg "pytest.mark.smoke" --type=py -B2 | grep "def test_"`, (2) For each smoke test file, search for VM creation patterns: `rg "VirtualMachineForTests|running_vm|VirtualMachineForTestsFromTemplate|wait_for_ssh|check_ssh_connectivity"`, (3) Trace the dependency chain: smoke test → VirtualMachineForTests/running_vm() → wait_for_ssh_connectivity() (default enabled) → vm.login_params property → py_config["os_login_param"][vm.os_flavor], (4) Check utilities/virt.py for login_params usage: `rg "os_login_param|login_params" utilities/virt.py -C3`. Any smoke test creating VMs with default SSH connectivity checks (running_vm with check_ssh_connectivity=True) depends on os_login_param, even if the test doesn't directly reference it.

The dependency chain is: smoke test → VM creation → running_vm → wait_for_ssh_connectivity → vm.login_params → os_login_param.

Learning: Applies to tests/**/test_*.py : When reviewing quarantine PRs, verify the quarantine mechanism matches the failure category. Product bugs (feature broken in product) use pytest.mark.jira("CNV-XXXXX", run=False). Automation issues or unidentified problems use pytest.mark.xfail(reason=f"{QUARANTINED}: ...", run=False). pytest.mark.jira is conditional and auto-re-enables when Jira is resolved. pytest.mark.xfail quarantine is unconditional and requires manual de-quarantine PR. If the quarantine reason describes a confirmed product behavior that is broken, use pytest.mark.jira. If the root cause is unclear, under investigation, or relates to test/automation/environment issues, use pytest.mark.xfail quarantine.
