[Storage] Add snapshot restore performance tests for multi-disk VMs#6042Ahmad-Hafe wants to merge 4 commits into
Conversation
📝 WalkthroughWalkthroughAdded Fedora four-disk VM and snapshot fixtures. Added grouped cleanup handling. Added single-VM and concurrent multi-VM restore tests with five-minute completion limits. ChangesMulti-disk snapshot restore validation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The concurrent snapshot-restore test can currently allow more than the required five-minute total because its timeout is applied separately across restore phases, weakening enforcement of the certification requirement. A required verification check is also failing, so the PR is not merge-ready until the deadline handling and verification failure are addressed.

restore fixture, established before submitting work, and apply it across
submission, deployment, and completion. In _restore_vm, compute the remaining
budget immediately before wait_restore_done and raise TimeoutError if it is
exhausted; pass only the remaining duration to that call. Ensure completion also
rejects restores that finish after the shared deadline while preserving existing
error logging and propagation.

When anSTP:link is present and linked-repo analysis finds missing or misaligned
scenarios, you MUST post an INLINE review comment on theSTP:line (or the module
docstring when the STP line is unchanged) containing:
- STP coverage: X/Y scenarios
- A table of each STP scenario → covered / missing / misaligned / deleted
- CRITICAL severity for missing P0 scenarios without documented exclusion in the PR
description (justification + follow-up Jira link per scenario)
Do NOT report STP coverage gaps only in PR conversation chat.STP alignment on modification and deletion
When a test referencing an
STP:URL is modified, use the same
inline-comment placement as the "STP traceability" section above: post on the
changed lines (docstring, assertion, or fixture) when available, otherwise fall
back to theSTP:line or module docstring.Modification (STP-linked tests only): Verify the modified docstring AND test
body still align with the linked STP scenario. Flag as HIGH with
"STP misalignment detected" and explain what changed vs. what the STP says.
This check does NOT apply to tests with onlyJira:orRFE:links (no STP
to compare against).Deletion (any traceability link): Handled by the "STP scenario coverage"
pre-merge check. Do not duplicate deletion comments here.special_infra marker enforcement

**: ## Approval Policy
You may approve the PR when ALL of the following are true:
- All your review comments have been addressed with either:
- a code/doc change that fixes the issue, or
- a substantive author response that justifies no code change.
Thread "resolved" state alone is not sufficient.
OR you had no review comments.- If you posted a test execution plan comment requesting tests, and the PR author replied
with a comment explaining why the requested tests are not needed or were already covered,
treat that as an acceptable response — do not block approval on the test plan alone.- The author's explanation must be reasonable and specific (not just "N/A" or "not needed").
Accept explanations like: "these tests were already run in CI", "this change is docs-only",
"the affected tests are quarantined", or "verified manually on cluster X".

raises in the VM setup, snapshot, restore, and test-body finally blocks to
preserve any active primary exception. Capture the active exception before
cleanup, then aggregate it with cleanup_errors when both exist, using raise-from
context as appropriate; retain the existing cleanup-only behavior when no
primary exception is active.

Placeholder test descriptions (STD) for snapshot restore performance: - test_restore_vm_with_4_disks_completes_within_five_minutes (CNV-16400) - test_restore_four_vms_with_4_disks_completes_within_five_minutes (CNV-16401) No implementation — __test__ = False prevents collection. Scenarios: 1. Single VM with 4 disks (1 boot from DataSource + 3 blank DVs): restore within 5 min 2. 4 VMs each with 4 disks: all restored concurrently within 5 min total Jira: CNV-88906 Signed-off-by: Ahmad Hafe <ahafe@redhat.com> Co-authored-by: Cursor <cursoragent@cursor.com>
Implements the STD for multi-disk snapshot restore performance: - test_restore_vm_with_4_disks_completes_within_five_minutes (CNV-16400) - test_restore_four_vms_with_4_disks_completes_within_five_minutes (CNV-16401) Each VM has 4 disk devices (1 boot from golden image DataSource + 3 blank DVs). The single-VM test asserts restore completes within 5 minutes. The 4-VM test restores all snapshots concurrently using a shared monotonic deadline and asserts total time <= 5 min. Fixtures: - create_vm_with_4_disks(): helper creating Fedora VM with blank DVs - vm_with_4_disks_for_snapshot / snapshot_of_vm_with_4_disks - four_vms_with_4_disks_for_snapshot / snapshots_of_four_vms - restored_vm_with_4_disks / restored_four_vms (concurrent via ThreadPoolExecutor) All restore resources are pre-created before submission for guaranteed cleanup.

Learning: In this repo’s OpenShift virtualization tests, it is a standard pattern to call `to_dict()` on `ocp-resources` objects (e.g., `DataVolume`) without using its return value. The call is used only to populate the object’s `res` attribute, which is then read or mutated (e.g., `dv.res[...] = ...`). Do not flag this as an unused return value and do not request adding an inline comment just to justify it, since maintainers treat this behavior as consistent and intentional across the codebase.

openshift-python-wrapper 11.0.140 VirtualMachineRestore __enter__ wait_restore_done source
💡 Result:
In the openshift-python-wrapper library, the VirtualMachineRestore resource and the wait_restore_done method do not appear to be part of the standard resource wrappers documented for virtual machine management [1][2]. While VirtualMachineRestore is a standard Kubernetes/KubeVirt API resource used for restoring virtual machines from snapshots [3][4][5], it is not exposed as a specific high-level class within the openshift-python-wrapper's primary resource library [1][2]. The term wait_restore_done does not exist in the source code of the openshift-python-wrapper [6][7]. The function name appears in unrelated technical contexts, such as terminal state management code in other projects [8], but it is not a feature of this library. For managing virtual machine snapshots and restores in OpenShift Virtualization, users typically interact with the VirtualMachineRestore resource directly via the generic Kubernetes client or OpenShift REST client, rather than through a dedicated wrapper class in this package [3][4]. Current documentation for openshift-python-wrapper emphasizes support for standard VM lifecycle operations like start, stop, and restart, as well as waiting for VMI statuses such as running [1][2].

HIGH: Enforce one five-minute deadline across deployment and both restore waits. VirtualMachineRestore.__enter__() deploys the resource before wait_restore_done() starts. wait_restore_done(timeout) then applies the same timeout separately to wait_complete() and wait_for_status_none(). The fixture can therefore exceed its documented five-minute budget. Create a monotonic deadline before the context and pass the remaining time to each wait.

What this PR does / why we need it:
Cloud provider GA certification requires that snapshot restore completes within 5 minutes for VMs with multiple disks.
This PR adds two tier3 conformance tests covering that requirement:
The 5-minute timeout is the pass/fail criterion, not a generous buffer — the test fails if restore takes longer.
Which issue(s) this PR fixes:
CNV-88908
Special notes for reviewer:
__test__ = False); commit 2 is the implementation; commit 3 addresses review comments (cleanup-before-deploy, chained cleanup errors, Google-format fixture docstrings)ThreadPoolExecutorwith a sharedtime.monotonic()deadline so the 5-minute budget covers all restores together, not each one independentlysnapshot_storage_class_name_scope_modulegates the test to storage classes that support snapshotsutilities/changes, so no utilities unit tests.
