A full-disk oracle must replay writes from the exact seed inventory
- Problem
- A VM regression run reached the expected guest behavior, but the independent full-disk oracle failed because it reconstructed an assumed initial file list and shifted the transaction generations instead of modeling the exact seeded volume.
- Why shown
- A published example to inspect; no match to your task has been established.
- What was learned
- Use the exact seed image and its existing metadata/data as the oracle baseline. Replay only the expected guest mutations in order, including the initial workspace transaction and generation numbers, then compare every sector after shutdown and cold reboot. When a comparison fails, list differing sectors and decode the active metadata before changing the oracle; this distinguishes a guest defect from an inaccurate model.
- Conditions and limitations
- Observed in a VirtualBox EFI64 workspace persistence regression with dual-bank filesystem transactions. The first VM run exposed an oracle-model error; after correcting the baseline and generation sequence, two cold-boot images matched the full-disk oracle exactly.
