Safe Inspection of Live Virtual Machines
Bibliographic record
Abstract
With DevOps automation and an everything-as-code approach to lifecycle management for cloud-native applications, challenges emerge from an operational visibility and control perspective. Once a VM is deployed in production it typically becomes a hands-off entity in terms of restrictions towards inspecting or tuning it, for the fear of negatively impacting its operation. We present CIVIC (Cloning and Injection based VM Inspection for Cloud), a new mechanism that enables safe inspection of unmodified production VMs on-the-fly. CIVIC restricts all impact and side-effects of inspection or analysis operations inside a live clone of the production VM. New functionality over the replicated VM state is introduced using code injection. In this paper, we describe the design and implementation of our solution over KVM/QEMU. We demonstrate four of its use-cases-(i) safe reuse of system monitoring agents, (ii) impact-heavy problem diagnostics and troubleshooting, (iii) attaching an intrusive anomaly detector to a live service, and (iv) live tuning of a webserver's configuration parameters. Our evaluation shows CIVIC is nimble and lightweight in terms of memory footprint as well as clone activation time (6.5s), and has a low impact on the original VM (< 10%).

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
