Short description:

add dedicated cpu instancetype test

More details:

Openshift ships with d1 series instance types, which have the DedicatedCPUPlacement field set.
Some instances of OpenShift deployment enforce the user to use DedicatedCPUPlacement in combination of windows, the added tests aim to replica the validation which occurs on the cluster and verify it is kept across future versions.

What this PR does / why we need it:

Add tests coverage for customer use case of d1 instance types

jira-ticket:

https://issues.redhat.com/browse/CNV-76513

Summary by CodeRabbit

  • Tests
    • Expanded Windows VM test infrastructure with registry-backed storage, data source provisioning, admission-policy scaffolding, and new fixtures to provision Windows images and VMs.
    • Added tests to verify dedicated CPU placement (vCPU pinning) and to assert admission-denied behavior for non-compliant Windows instance types.
    • Added a utility to validate vCPU pinning for dedicated CPU profiles.
  • Chores
    • Introduced a named OS flavor constant to standardize Windows VM selection in tests.

📝 Walkthrough

Walkthrough

Adds Windows-focused test fixtures (admission policies, registry-backed DataVolume/DataSource, Windows VM fixture), two dedicated-CPU Windows tests, a vCPU-pinning verification utility, and a constant for the Windows container-disk OS flavor.

Changes

Cohort / File(s) Summary
Test infrastructure fixtures
tests/infrastructure/instance_types/conftest.py
Added five class-scoped fixtures: windows_validating_admission_policy, windows_validating_admission_policy_binding, latest_windows_data_volume, latest_windows_data_source, and windows_vm_for_dedicated_cpu to provision admission policies, registry-backed DataVolume/DataSource, and a Windows VM for dedicated-CPU tests.
Dedicated-CPU tests
tests/infrastructure/instance_types/test_common_vm_instancetype.py
Added TestDedicatedInstancetypeProfile with test_d1_instancetype_profile and test_dedicated_cpu_validation_error to verify dedicated-CPU placement and admission-denied behavior for Windows VMs.
Verification utility
tests/infrastructure/instance_types/utils.py
Added verify_dedicated_cpu_placement(vm: VirtualMachineForTests) and is_valid_cpuset(cpuset: str) to parse VMI libvirt XML, assert vcpupin count matches expected vCPU count, validate cpuset formats, and check emulatorpin separation.
Supported OS flavor constant
utilities/constants.py, tests/infrastructure/instance_types/supported_os/conftest.py
Added OS_FLAVOR_WIN_CONTAINER_DISK = "win-container-disk" and replaced hard-coded "win-container-disk" usage with the new constant.

133-149: ⚠️ Potential issue | 🟡 Minor

MEDIUM: Add Google‑style docstring + avoid list materialization in any()

As per coding guidelines, Google-format docstrings REQUIRED for all public functions with non-obvious return values OR side effects.

🤖 Fix all issues with AI agents
In `@tests/infrastructure/instance_types/conftest.py`:
- Around line 53-106: Rename the verb-named fixtures
deployed_validating_admission_policy and
deployed_validating_admission_policy_binding to noun-based names (e.g.,
validating_admission_policy and validating_admission_policy_binding) and update
any `@pytest.mark.usefixtures` references in test_common_vm_instancetype.py to the
new names; while renaming, preserve existing parameters, scope="class" and
context-manager usage (ValidatingAdmissionPolicy /
ValidatingAdmissionPolicyBinding) so behavior doesn't change. Add concise
Google-style docstrings above each fixture describing what the fixture provides
and any side effects (e.g., "Creates and yields a ValidatingAdmissionPolicy that
enforces Windows VMI CPU placement" and similarly for the binding). Ensure the
fixture names are public (no leading underscores) and return/yield behavior is
documented.
- Around line 151-166: The fixture windows_vm_for_dedicated_cpu is currently
declared with scope="class" but provisions a mutable VM; change its fixture
scope to "function" to ensure per-test isolation by updating the `@pytest.fixture`
decorator (or removing the scope param to use the default function scope) for
the windows_vm_for_dedicated_cpu fixture; keep the body using
VirtualMachineForTests, VirtualMachineClusterInstancetype,
VirtualMachineClusterPreference, and data_volume_template_with_source_ref_dict
unchanged but verify no tests depend on class-scoped reuse.
- Around line 136-148: The fixture latest_windows_data_source currently accepts
an unused parameter namespace, triggering Ruff ARG001; fix it by either using
the provided namespace when constructing the DataSource (replace
latest_windows_data_volume.namespace with namespace in the DataSource(...) call)
or by removing namespace from the fixture signature and any references to it so
the fixture only uses latest_windows_data_volume, DataSource, and
generate_data_source_dict; choose the option that matches intended test
behavior.
- Around line 109-134: The fixture latest_windows_data_volume is declared with
class scope causing shared DataVolume resources; change the pytest fixture
decorator to use function scope so each test gets an isolated DataVolume
instance. Update the `@pytest.fixture`(scope="class") on
latest_windows_data_volume to `@pytest.fixture`(scope="function"), leaving the
DataVolume(...) context usage, secret/config map retrieval via
get_artifactory_secret and get_artifactory_config_map, and the cleanup call to
cleanup_artifactory_secret_and_config_map unchanged.

In `@tests/infrastructure/instance_types/test_common_vm_instancetype.py`:
- Around line 1-14: The file defines an unused LOGGER variable and imports
logging unnecessarily; remove the logging import and the LOGGER =
logging.getLogger(__name__) line to eliminate dead code (search for the symbol
LOGGER and the logging import at the top of
tests/infrastructure/instance_types/test_common_vm_instancetype.py and delete
both). If you prefer to keep logging, instead use LOGGER in test output or debug
statements within this module, but the simpler fix is to remove the unused
import and LOGGER definition.

In `@tests/infrastructure/instance_types/utils.py`:
- Around line 67-83: The verify_dedicated_cpu_placement function assumes
vm.privileged_vmi.xml_dict["domain"]["cputune"]["vcpupin"] is always a list;
normalize that value to a list (wrap a single dict into [dict]) before building
vcpupin_cpusets, add an assertion that "cputune" and "vcpupin" exist in
vm.privileged_vmi.xml_dict["domain"] to fail fast with a clear message, then
iterate the normalized list and perform the existing isdigit/“-”/“,” checks for
each vcpupin["@cpuset"] to avoid crashes when only one vcpupin is present.

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"

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: 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 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: 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, 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.

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: The test execution plan for PR `#1904` focuses on cluster-type conditional logic where nmstate functionality is bypassed on cloud clusters (Azure/AWS) but fully functional on bare-metal/PSI clusters, requiring different test strategies for each environment type.

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 the openshift-virtualization-tests repo, PR `#2199` depends on PR `#2139` which adds architecture-specific OS_FLAVOR attributes to the Images.Cirros class (OS_FLAVOR_CIRROS for x86_64/ARM64, OS_FLAVOR_FEDORA for s390x), enabling conditional logic based on the underlying OS flavor in tests.

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.

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.

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 RedHatQE/openshift-virtualization-tests project, servolkov's team always uses bare metal (BM) clusters with IPv4 setup in their testing environment, making defensive checks for IPv4 data presence potentially redundant in their networking code.

Learning: In the openshift-virtualization-tests repository, user rnetser prefers to keep pagination loops inline rather than extracting them into generic helper functions when the loops have different URL patterns and unique post-processing logic, as the inline approach improves readability and makes each endpoint's behavior more explicit.

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.

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.
