Summary

• Fix the LUKS test suite description in README to accurately reflect test purpose
• Previous description framed the tests as verifying disk encryption preservation
• Actual purpose: validating MTV's credential handling during ImageConversion — both successful migration with correct credentials and expected failure with invalid credentials

Summary by CodeRabbit

• Documentation
  • Updated the LUKS disk encryption migration section to clarify what the suite validates during VM migration.
  • The description now focuses on decryption secret handling during the image conversion phase, covering both successful migrations with correct credentials and expected failures with invalid credentials.

Warning

Review limit reached

@MiriSafra, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 26 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Fix README LUKS test suite description to match actual coverage

📝 Documentation 🕐 Less than 5 minutes

AI Description

• Clarify the LUKS migration test suite purpose and what it validates.
• Document ImageConversion credential handling: success with valid secrets, failure with invalid
 ones.

High-Level Assessment

The PR’s approach is optimal: directly correct the README to reflect what the LUKS test suite actually validates (MTV credential handling during ImageConversion). No architectural or implementation alternatives apply for a pure documentation clarification.

Correct LUKS test suite description to focus on credential handling

• Replaces an inaccurate description that implied verifying post-migration encryption preservation via 'lsblk'. Updates the text to describe the real intent: validating MTV’s processing of decryption secrets during ImageConversion, covering both valid-credential success and invalid-credential failure cases.

1. LUKS README misses encryption check ✗ Dismissed 🐞 Bug ⚙ Maintainability

Description

The updated README reframes the LUKS tier1 suite as validating secret handling and ImageConversion
failure paths, but it omits that the success-path test still explicitly verifies encryption remains
active post-migration via lsblk/crypto_LUKS checks. This can mislead maintainers about what the
suite asserts today.

Code

README.md[R594-597]

+This test suite verifies MTV's ability to handle the migration of LUKS-encrypted VMs. It ensures
+that MTV correctly processes decryption secrets during the ImageConversion phase, validating both
+successful migration when correct credentials are provided and expected failure when invalid
+credentials are used.

PR-#557

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

The README paragraph now only describes secret handling and ImageConversion failure behavior, while
the actual test suite still calls verify_luks_encryption() after a successful migration and that
helper asserts crypto_LUKS devices exist in lsblk output.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
The README’s LUKS test-suite description no longer mentions that the successful migration test verifies LUKS encryption is still active after migration (by inspecting `lsblk` output for `crypto_LUKS`).

### Issue Context
The test suite validates both: (1) correct secret handling to allow ImageConversion to succeed, and (2) a post-migration assertion that encrypted devices still appear on the migrated VM.

2. Ambiguous credentials wording ✓ Resolved 🐞 Bug ⚙ Maintainability

Description

README.md describes the negative-path LUKS test as failing with “invalid credentials”, but the
actual test scenario varies only the LUKS decryption passphrase (luks_passphrase). This ambiguity
can mislead readers into troubleshooting provider/guest credentials rather than the LUKS passphrase
configuration.

Code

README.md[R594-596]

+This test suite verifies MTV's ability to migrate LUKS-encrypted VMs. It validates both
+successful cold migration when the correct decryption passphrase is provided, and expected
+failure at the ImageConversion phase when invalid credentials are used.

PR-#561
PR-#187

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

The README uses the generic term “invalid credentials”, but the LUKS tests and internal guidance
consistently describe the parameter under test as the LUKS passphrase (luks_passphrase), not
general provider/guest credentials.

AGENTS.md[801-804]

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
The README’s LUKS suite description says failures occur with “invalid credentials”, but the test suite’s negative case is specifically about an **incorrect LUKS decryption passphrase**. This wording is ambiguous and can confuse users about what to configure/debug.

### Issue Context
- The wrong-key test is explicitly “incorrect LUKS passphrase” and expects failure at `ImageConversion`.
- The README configuration immediately below uses the `luks_passphrase` key.

### Fix Focus Areas
- README.md[594-596]

### Suggested change
Update the last clause to be explicit, e.g.:
- “…failure at the ImageConversion phase when an **incorrect LUKS decryption passphrase** is used.”
