📝 Walkthrough

Walkthrough

Adds node-level NVIDIA vGPU labeling fixtures and waits, sandbox-validator and sandbox device-plugin orchestration utilities, new NVIDIA/GPU constants and labels, updates HCO mediatedHostDevices payloads to include externalResourceProvider, and adjusts fixture signatures to incorporate the vGPU readiness flow.

Changes

Cohort / File(s) Summary
Top-level vGPU fixtures
tests/virt/conftest.py
Added gpu_nodes_labeled_with_vgpu_config fixture; updated gpu_nodes_labeled_with_vm_vgpu signature to accept it; vgpu_ready_nodes now depends on the new fixture and waits for NVIDIA vgpu device-manager and sandbox validator/device-plugin readiness.
Node vGPU fixtures & labeling
tests/virt/node/gpu/vgpu/conftest.py
Added fixtures: sandbox_validator_pods_before_grid_relabel, node_labeled_with_grid_vgpu_config, ready_node_with_grid_vgpu_config; moved relabel/wait logic out of HCO fixture; added LOGGER; switched to VGPU_CONFIG_LABEL; HCO fixture now depends on ready_node_with_grid_vgpu_config; added externalResourceProvider: True in permittedHostDevices entries.
GPU orchestration utilities
tests/virt/node/gpu/utils.py
Added sandbox-related helpers: get_sandbox_validator_pods, wait_for_new_sandbox_validator_pods (two-phase wait with fallback label toggle), wait_for_sandbox_device_plugin_ds, toggle_vgpu_config_label, and wait_for_sandbox_validator_pods; introduced logging and sandbox DS/name/timeouts/constants.
GPU constants & labels
tests/virt/node/gpu/constants.py
Added constants: NVIDIA_VGPU_DEVICE_MANAGER_DS, NVIDIA_SANDBOX_VALIDATOR_DS, NVIDIA_SANDBOX_DEVICE_PLUGIN_DS, SANDBOX_DEVICE_PLUGIN_DEPLOY_LABEL, VGPU_CONFIG_LABEL, GPU_WORKLOAD_CONFIG_LABEL; updated A2 vGPU name strings.
HCO CR payload changes
tests/virt/utils.py, tests/virt/node/gpu/vgpu/conftest.py
Modified HCO mediatedHostDevices payloads: removed mediatedDevicesConfiguration and added externalResourceProvider: True inside each permittedHostDevices.mediatedDevices entry.
Label constant refactor
tests/virt/node/gpu/gpu_pci_passthrough/conftest.py
Replaced hard-coded label key "nvidia.com/gpu.workload.config" with GPU_WORKLOAD_CONFIG_LABEL constant.
Test docs
tests/virt/node/gpu/vgpu/test_rhel_vm_with_vgpu.py
Reworded docstrings to reference node-specific vGPU configuration via the GPU operator (nvidia.com/vgpu.config); no behavior changes.

describing parameters (admin_client, namespace_name, pod_prefix,
expected_number_of_pods, number_of_consecutive_checks, timeout), return value

logging using LOGGER.info and LOGGER.error with an extra dict (e.g. keys:

Test execution plan request details

CRITICAL: You MUST post an inline review comment on the first changed line of the first file.
The inline comment should contain the Test Execution Plan with the smoke tests recommendation.
Do NOT submit a formal review - just post the inline comment directly.

As an expert software testing engineer, analyze all modified files in this PR and create a targeted test execution plan.
You will post an inline review comment with the test execution plan on the first changed file.
If you fail to run or post a comment, retry.

Analysis Requirements:

  1. Examine code changes in each modified file
  2. Identify affected code paths, functions, and classes
  3. Analyze pytest-specific elements: fixtures (scope, dependencies), parametrization, markers, conftest changes
  4. Trace test dependencies through imports, shared utilities, and fixture inheritance
  5. Detect new tests introduced in the PR
  6. Smoke Test Impact Analysis: Determine if any changes could affect smoke tests by checking:
    • Changes to files/functions used by tests marked with @pytest.mark.smoke
    • Changes to fixtures or utilities imported by smoke tests
    • Changes to conftest.py files that may affect smoke test execution
    • Changes to core infrastructure code (utilities/, libs/) that smoke tests depend on

Your deliverable:
Your change request comment will be based on the following requirements:

Test Execution Plan

  • Run smoke tests: True / False (Based on your smoke test impact analysis - True if any changes may affect smoke tests)
  • path/to/test_file.py - When the entire test file needs verification
  • path/to/test_file.py::TestClass::test_method - When specific test(s) needed
  • path/to/test_file.py::test_function - When specific test(s) needed
  • -m marker - When specific marker(s) can be used to cover multiple cases.

Guidelines:

  • Include only tests directly affected by the changes
  • Use a full file path only if ALL tests in that file require verification
  • Use file path + test name if only specific tests are needed
  • If a test marker can cover multiple files/tests, provide the marker
  • Balance coverage vs over-testing - Keep descriptions minimal

Hardware-Related Checks (SR-IOV, GPU, DPDK):

When PR modifies fixtures for hardware-specific resources:

  • Collection Safety: Fixtures MUST have existence checks (return None when hardware unavailable)
  • Test Plan: MUST verify both WITH and WITHOUT hardware:
    • Run affected tests on cluster WITH hardware
    • Verify collection succeeds on cluster WITHOUT hardware

CRITICAL WORKFLOW COMPLETION RULES:

When responding to this test execution plan request, you MUST follow these rules EXACTLY:

  1. YOUR ONLY DELIVERABLE: Post an inline review comment containing the test execution plan on the first changed line
  2. THEN STOP IMMEDIATELY - Do NOT generate any additional response
  3. FALLBACK ONLY: If submitting the review fails after retrying, post as a regular PR comment
  4. SILENCE = SUCCESS: After successfully submitting the review, your task is complete. No confirmation needed.

ABSOLUTE PROHIBITIONS (violating these creates empty/meaningless reviews):

  • ❌ Do NOT post acknowledgment messages like "Test execution plan posted", "Review posted successfully", "I've successfully posted"
  • ❌ Do NOT mention review IDs, URLs, or confirmation of posting in the PR thread
  • ❌ Do NOT add any follow-up comments after submitting the review
  • ❌ Do NOT reply to confirm task completion
  • ❌ Do NOT explain what you did - just do it and stop

Remember: The pull request review is visible to users. Additional comments are redundant noise.

CRITICAL: Before setting "Run smoke tests: True", you MUST use shell scripts to:
- Trace the actual fixture dependency chain from smoke tests to changed fixtures
- Verify that smoke tests actually import/use changed utilities or functions
- Confirm the dependency path exists; do NOT assume based on scope or semantics
- Be conservative: Session-scoped fixtures or infrastructure-sounding names do NOT
automatically mean smoke test impact. Only flag smoke test impact when you can
demonstrate a concrete dependency path.
WRONG: "This session-scoped storage fixture might affect smoke tests"
RIGHT: "Smoke test X uses fixture Y, which depends on the changed fixture Z"

**Run smoke tests: False**

> No traceable dependency path exists from smoke tests to the changed GPU/vGPU fixtures or utilities.

### ⚠️ GPU Hardware Required — Verify Both WITH and WITHOUT Hardware

**WITH GPU hardware** (functional verification):
- `tests/virt/node/gpu/vgpu/test_rhel_vm_with_vgpu.py`
- `tests/virt/node/gpu/vgpu/test_windows_vm_with_vgpu.py`
- `tests/virt/upgrade_custom/vgpu/test_vgpu_vm_upgrade.py`

**GPU PCI Passthrough** (conftest changed):
- `tests/virt/node/gpu/gpu_pci_passthrough/`

**WITHOUT GPU hardware** (collection safety):
- `pytest --collect-only tests/virt/node/gpu/` — must complete with no collection errors

### Changed Components
| File | Change |
|------|--------|
| `tests/virt/conftest.py` | New: `gpu_nodes_labeled_with_vgpu_config`; expanded `vgpu_ready_nodes` with CNV-77535 workaround |
| `tests/virt/node/gpu/constants.py` | Device names: NVIDIA_A2-2Q/4Q (from GRID format); new sandbox constants |
| `tests/virt/node/gpu/vgpu/conftest.py` | Removed `mediatedDevicesConfiguration`; added `externalResourceProvider: True`; new sandbox validator fixtures |
| `tests/virt/node/gpu/gpu_pci_passthrough/conftest.py` | `GPU_WORKLOAD_CONFIG_LABEL` constant substituted |
| `tests/virt/node/gpu/utils.py` | New sandbox orchestration utilities added |
| `tests/virt/utils.py` | `patch_hco_cr_with_mdev_permitted_hostdevices` payload updated |'

Timestamp: 2025-12-16T20:11:03.645Z
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.

Timestamp: 2025-12-16T15:09:49.597Z
Learning: In the openshift-virtualization-tests repository, when conftest.py or utilities/bitwarden.py changes affect py_config["os_login_param"], smoke test impact must be determined by: (1) finding all smoke tests using `rg "pytest.mark.smoke"`, (2) checking each for VM creation patterns (VirtualMachineForTests, running_vm, VirtualMachineForTestsFromTemplate), (3) tracing whether running_vm is called with default check_ssh_connectivity=True, which accesses vm.login_params property that reads py_config["os_login_param"][vm.os_flavor]. The dependency chain is: smoke test → VM creation → running_vm → wait_for_ssh_connectivity → vm.login_params → os_login_param. Any smoke test creating VMs with SSH connectivity (the default) depends on os_login_param.

Learning: In the openshift-virtualization-tests repository, when determining smoke test impact for test execution plans, only set "Run smoke tests: True" if there is a verified, traceable dependency path from smoke tests to the changed code. Session-scoped fixtures or infrastructure-sounding changes do NOT automatically imply smoke test impact - the dependency chain must be explicitly verified using shell scripts before recommending smoke test execution.

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: For PRs that only remove or modify pytest markers (like removing pytest.mark.post_upgrade) without changing test logic in openshift-virtualization-tests, collection verification using `pytest --collect-only` is sufficient. Full test execution is not required to verify marker-only changes.

Learning: In the openshift-virtualization-tests repository, when responding to test execution plan requests from openshift-virtualization-qe-bot-3, CodeRabbit must post ONLY an inline review comment on the Files Changed tab and then stop immediately without generating any follow-up comments in the PR discussion thread. No acknowledgment messages, no confirmation of posting, no explanation - silence after posting the inline review equals success. Additional comments create empty/meaningless reviews that clutter the PR.

Learning: For PRs that remove test cases (especially redundant test cleanup PRs in openshift-virtualization-tests), test collection verification (pytest --collect-only showing selected/deselected counts) is sufficient to confirm the removal was clean and the test module remains functional. Full test execution is not required for test deletion PRs.

Learning: In the openshift-virtualization-tests repository, when posting test execution plan inline review comments using GitHub API, the full test execution plan content must go in the `comments[].body` field (which appears on Files Changed tab), NOT in the top-level `body` field (which appears in PR discussion thread). The top-level `body` field should be omitted or left empty to avoid posting redundant comments in the PR discussion thread.

Timestamp: 2026-03-19T10:37:02.008Z
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.

Timestamp: 2026-01-25T13:18:26.819Z
Learning: In the openshift-virtualization-tests repository, user jpeimer prefers to avoid nitpicky style changes (e.g., removing `.keys()` from dict membership checks) because verifying every change is expensive. Be cautious about suggesting low-impact stylistic improvements that require verification overhead.

Timestamp: 2025-11-26T16:03:07.813Z
Learning: In the openshift-virtualization-tests repository, pytest fixtures that declare other fixtures as parameters purely for dependency ordering (without referencing them in the function body) should not be modified to silence Ruff ARG001 warnings. This is an idiomatic pytest pattern for ensuring setup order, and the team prefers to leave such fixtures unchanged rather than adding defensive comments or code to suppress linter warnings.

Learning: In the openshift-virtualization-tests repository, user rnetser prefers to keep refactoring PRs (like PR `#2469`) strictly focused on moving/organizing code into more granular modules without adding new functionality, error handling, or behavioral changes. Such improvements should be handled in separate PRs.

Timestamp: 2026-02-23T18:08:05.929Z
Learning: In the openshift-virtualization-tests repository, FBT001 Ruff warnings (Boolean-typed positional argument in function definition) for pytest fixture parameters should not be flagged or require fixes. Pytest injects all fixture parameters by name through dependency injection, making the boolean positional argument concern a false positive in this context. This applies to fixture definitions across all test files under tests/.

Learning: In the RedHatQE/openshift-virtualization-tests repository, when introducing STD (Standard Test Definition) PRs that define test case structure without implementation, it's acceptable and intentional to use `__test__ = False` to block pytest collection until the tests are fully implemented in a follow-up PR. The STD workflow involves: (1) defining test structure, markers, and documentation first, (2) implementing the actual test logic and removing the collection blocker in a subsequent PR.

Test execution plan request details

CRITICAL: You MUST post an inline review comment on the first changed line of the first file.
The inline comment should contain the Test Execution Plan with the smoke tests recommendation.
Do NOT submit a formal review - just post the inline comment directly.

As an expert software testing engineer, analyze all modified files in this PR and create a targeted test execution plan.
You will post an inline review comment with the test execution plan on the first changed file.
If you fail to run or post a comment, retry.

Analysis Requirements:

  1. Examine code changes in each modified file
  2. Identify affected code paths, functions, and classes
  3. Analyze pytest-specific elements: fixtures (scope, dependencies), parametrization, markers, conftest changes
  4. Trace test dependencies through imports, shared utilities, and fixture inheritance
  5. Detect new tests introduced in the PR
  6. Smoke Test Impact Analysis: Determine if any changes could affect smoke tests by checking:
    • Changes to files/functions used by tests marked with @pytest.mark.smoke
    • Changes to fixtures or utilities imported by smoke tests
    • Changes to conftest.py files that may affect smoke test execution
    • Changes to core infrastructure code (utilities/, libs/) that smoke tests depend on

Your deliverable:
Your change request comment will be based on the following requirements:

Test Execution Plan

  • Run smoke tests: True / False (Based on your smoke test impact analysis - True if any changes may affect smoke tests)
  • path/to/test_file.py - When the entire test file needs verification
  • path/to/test_file.py::TestClass::test_method - When specific test(s) needed
  • path/to/test_file.py::test_function - When specific test(s) needed
  • -m marker - When specific marker(s) can be used to cover multiple cases.

Guidelines:

  • Include only tests directly affected by the changes
  • Use a full file path only if ALL tests in that file require verification
  • Use file path + test name if only specific tests are needed
  • If a test marker can cover multiple files/tests, provide the marker
  • Balance coverage vs over-testing - Keep descriptions minimal

Hardware-Related Checks (SR-IOV, GPU, DPDK):

When PR modifies fixtures for hardware-specific resources:

  • Collection Safety: Fixtures MUST have existence checks (return None when hardware unavailable)
  • Test Plan: MUST verify both WITH and WITHOUT hardware:
    • Run affected tests on cluster WITH hardware
    • Verify collection succeeds on cluster WITHOUT hardware

CRITICAL WORKFLOW COMPLETION RULES:

When responding to this test execution plan request, you MUST follow these rules EXACTLY:

  1. YOUR ONLY DELIVERABLE: Post an inline review comment containing the test execution plan on the first changed line
  2. THEN STOP IMMEDIATELY - Do NOT generate any additional response
  3. FALLBACK ONLY: If submitting the review fails after retrying, post as a regular PR comment
  4. SILENCE = SUCCESS: After successfully submitting the review, your task is complete. No confirmation needed.

ABSOLUTE PROHIBITIONS (violating these creates empty/meaningless reviews):

  • ❌ Do NOT post acknowledgment messages like "Test execution plan posted", "Review posted successfully", "I've successfully posted"
  • ❌ Do NOT mention review IDs, URLs, or confirmation of posting in the PR thread
  • ❌ Do NOT add any follow-up comments after submitting the review
  • ❌ Do NOT reply to confirm task completion
  • ❌ Do NOT explain what you did - just do it and stop

Remember: The pull request review is visible to users. Additional comments are redundant noise.

CRITICAL: Before setting "Run smoke tests: True", you MUST use shell scripts to:
- Trace the actual fixture dependency chain from smoke tests to changed fixtures
- Verify that smoke tests actually import/use changed utilities or functions
- Confirm the dependency path exists; do NOT assume based on scope or semantics
- Be conservative: Session-scoped fixtures or infrastructure-sounding names do NOT
automatically mean smoke test impact. Only flag smoke test impact when you can
demonstrate a concrete dependency path.
WRONG: "This session-scoped storage fixture might affect smoke tests"
RIGHT: "Smoke test X uses fixture Y, which depends on the changed fixture Z"

**Run smoke tests: False**

> No traceable dependency path exists from smoke tests to the changed GPU/vGPU fixtures or utilities.

### ⚠️ GPU Hardware Required — Verify Both WITH and WITHOUT Hardware

**WITH GPU hardware** (functional verification):
- `tests/virt/node/gpu/vgpu/test_rhel_vm_with_vgpu.py`
- `tests/virt/node/gpu/vgpu/test_windows_vm_with_vgpu.py`
- `tests/virt/upgrade_custom/vgpu/test_vgpu_vm_upgrade.py`

**GPU PCI Passthrough** (conftest changed):
- `tests/virt/node/gpu/gpu_pci_passthrough/`

**WITHOUT GPU hardware** (collection safety):
- `pytest --collect-only tests/virt/node/gpu/` — must complete with no collection errors

### Changed Components
| File | Change |
|------|--------|
| `tests/virt/conftest.py` | New: `gpu_nodes_labeled_with_vgpu_config`; expanded `vgpu_ready_nodes` with CNV-77535 workaround |

Timestamp: 2025-12-16T20:11:03.645Z
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.

Learning: In the openshift-virtualization-tests repository, when conftest.py or utilities/bitwarden.py changes affect py_config["os_login_param"], smoke test impact must be determined by: (1) finding all smoke tests using `rg "pytest.mark.smoke"`, (2) checking each for VM creation patterns (VirtualMachineForTests, running_vm, VirtualMachineForTestsFromTemplate), (3) tracing whether running_vm is called with default check_ssh_connectivity=True, which accesses vm.login_params property that reads py_config["os_login_param"][vm.os_flavor]. The dependency chain is: smoke test → VM creation → running_vm → wait_for_ssh_connectivity → vm.login_params → os_login_param. Any smoke test creating VMs with SSH connectivity (the default) depends on os_login_param.

Learning: In the openshift-virtualization-tests repository, when determining smoke test impact for test execution plans, only set "Run smoke tests: True" if there is a verified, traceable dependency path from smoke tests to the changed code. Session-scoped fixtures or infrastructure-sounding changes do NOT automatically imply smoke test impact - the dependency chain must be explicitly verified using shell scripts before recommending smoke test execution.

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: In the openshift-virtualization-tests repository, pytest fixtures that declare other fixtures as parameters purely for dependency ordering (without referencing them in the function body) should not be modified to silence Ruff ARG001 warnings. This is an idiomatic pytest pattern for ensuring setup order, and the team prefers to leave such fixtures unchanged rather than adding defensive comments or code to suppress linter warnings.

Learning: In the openshift-virtualization-tests repository, FBT001 Ruff warnings (Boolean-typed positional argument in function definition) for pytest fixture parameters should not be flagged or require fixes. Pytest injects all fixture parameters by name through dependency injection, making the boolean positional argument concern a false positive in this context. This applies to fixture definitions across all test files under tests/.

Learning: In the RedHatQE/openshift-virtualization-tests repository, tests run sequentially by default on the same cluster (with module-scoped fixtures properly cleaned up between modules), and parallel test runs use different machines/clusters. This means cluster-scoped resources (like ClusterUserDefinedNetwork or NodeNetworkConfigurationPolicy) can safely use the same names across different test modules without risk of collision.

Learning: In OpenShift Virtualization tests, MigrationPolicy fixtures should use static names rather than unique suffixes to enable collision detection. If parallel test runs collide on cluster-scoped resource names like MigrationPolicy, it's better to know about the collision rather than hide it with unique naming, as confirmed by maintainer dshchedr.

Learning: In OpenShift Virtualization mass machine type transition tests, the machine type glob pattern "pc-q35-rhel8.*.*" is intentionally hard-coded in the kubevirt_api_lifecycle_automation_job as it's used only once for this specific test case, with plans to update it in the future if the job needs to support other machine types.

Learning: In the RedHatQE/openshift-virtualization-tests repository, CentOS preferences follow the format "centos-stream<version>" (e.g., "centos-stream9", "centos-stream10"). The generate_instance_type_centos_os_matrix function correctly uses regex to extract numeric versions and constructs the latest version string in the same format as the input preferences for proper comparison.
