- New GET /api/v1/storage/pools returns available lvmthin/zfspool/rbd/dir pools
- Analysis result template now shows dropdown when >1 pool available
- Falls back to text input with single pool or on discovery failure
- Backend /api/v1/analyze now returns 202 with analysis_id immediately
- New GET /api/v1/analyze/{id} for polling analysis status
- Background thread handles extraction, disk discovery, OS/EFI detection
- Nested archive extraction: handles chained zips and split zips (.z01-.zNN)
- Frontend polls /session/analyze/status/{id} every 2s until complete
- SCP page now has complete confirm form flow with job polling
Runs 'ssh stat -c%s' or 'ls -l' to get total bytes before starting
SCP transfer. Progress bar now shows real percentage and ETA
instead of indeterminate spinner.
Replaces flat 30 GB default with proportional sizing:
- 500 GB → 50 GB, 200 GB → 20 GB, 80 GB → 20 GB
- Less aggressive for large disks, safer for GRUB boot
- Update UI hint and README to reflect new rule
Replaces wget with aria2c -x8 -s8 for significantly faster
downloads, especially on high-latency connections. Falls back to
single-connection if the server doesn't support range requests.
- Backend cleanup_staging accepts session_id, deletes whole
STAGING_ROOT/{guid}/ dir when provided
- CleanupRequest model gets session_id field
- Frontend cleanup proxy passes session_id from body
- api_client passes session_id to backend
- reuseImage JS includes session_id in cleanup payload
1. submit_job() was creating empty tmp/out/{vmid}/ dirs via the old
flat STAGING_OUT path. Removed — _process_job handles this via
_staging_out() in the session-aware path.
2. Copy (re-convert) flow was hardcoding boot_type=uefi. Now uses
auto_detect_boot=true with boot_type=legacy as fallback, matching
the behavior of the original analyze→convert flow.
When files are stored in /mnt/converter/in/{guid}/, the backend
needs the full relative path. The analyze endpoint now constructs
'{guid}/{filename}' before passing to the backend API.
Each browser gets a UUID stored in localStorage, set as a cookie,
and attached to every API call. Files go to session-specific dirs:
/mnt/converter/in/{guid}/ — uploads, downloads, SCP pulls
/mnt/converter/out/{guid}/ — converted QCOW2s
Changes:
- base.html: generates UUID via crypto.randomUUID(), stores in
localStorage + cookie, exposes as window.VM_BENCH_SID
- Frontend: all endpoints accept session_id, _staging() helper
creates session-aware paths on demand
- JavaScript: session_id appended to all FormData, set as
X-Session-ID header on raw uploads
- Backend models: JobSubmissionRequest.session_id field added
- Provisioner: _staging_in/_staging_out helpers, source path
resolution uses session-aware directory
- Converter: extract_if_needed skips re-extraction if dir exists
Rewrote to match actual Proxmox VE light interface:
- #f0f0f0 page background, white panels
- Dark blue header (#1b3a5c) with white text
- Light gray panel headers (#f8f8f8)
- Bootstrap-style alert colors (yellow/blue/green/red)
- Orange accent throughout
After conversion completes, the user sees a form with VM Name and ID
prefilled, and three buttons:
- Clone (instant): qm clone --full via backend, takes seconds
- Copy (re-convert): shows CPU/RAM/Disk fields, re-runs full pipeline
- Clean Up & Finish: deletes staging, returns to start page
Backend: new /api/v1/clone endpoint → provisioner.clone_vm()
Frontend: new /session/clone proxy, api_client.clone_vm()
1. BIOS: provisioner now calls detect_efi() on the first disk when
auto_detect_boot=true. Detects EFI partition via guestfish.
Falls back to user's boot_type if detection inconclusive.
2. Reuse: 'Create Another VM' now shows an inline form asking only
for VM Name and ID, reusing the same disk image, format, and
boot settings from the completed job. No redirect needed.
Previously always showed indeterminate spinner (pct=0) because
total size was unknown. Now if the HEAD request returns
Content-Length, the progress bar fills proportionally.
The 10s HEAD request for Content-Length blocked the download endpoint
response. nginx proxy in front (bench.srv2.sechpoint.app:443 → :5000)
timed out waiting, returned empty response → 'data is null' JS error.
Now wget starts immediately, response returns instantly, and HEAD
runs in a daemon thread to populate content_length for ETA later.
The fill.style.width = pct + '%' line was lost during a previous edit,
so the progress bar element was found but never visually updated.
Events fired, label updated, but bar stayed at 0%.
Starlette's multipart parser (pure Python) is too slow for >1 GB uploads —
boundary scanning over gigabytes blocks the event loop indefinitely.
New /session/upload-raw endpoint:
- Receives raw binary body via request.stream() — no parsing overhead
- Metadata (filename, vmid, vm_name) passed in HTTP headers
- Async chunked write directly to staging — true zero-copy streaming
- Same progress logging as before
Frontend now sends File object directly via xhr.send(file)
instead of FormData — eliminates multipart encoding on the client too.
New /scp page with form for host, user, password, remote path.
Runs scp via sshpass in background with progress polling.
Files go to /mnt/converter/in/{session_id}/ for multi-user isolation.
- Added sshpass + openssh-client to frontend installer
- scp.html template with full form + progress bar
- POST /scp/start — launches background SCP via sshpass -e
- GET /scp/progress/{sid}/{file} — polls file size + speed
- 'SCP Pull (+10 GB)' button on start page
innerHTML reset in startSession was destroying #phase-label and
#progress-fill elements, then recreating them with same IDs. XHR
progress events fired asynchronously but getElementById might
return stale references or fail during the DOM update window.
Now #phase-label, #progress-fill, and #session-error are permanent
elements in the static HTML. startSession clears them via
textContent/style instead of innerHTML — no DOM destruction.
showError appends to #session-error instead of #session-status.
- HTTP middleware logs every incoming request (method, path, body size)
BEFORE handler runs — catches silent failures at the network/parser layer
- Changed upload handler from async to sync so FastAPI runs it
in a thread pool, preventing event loop blockage during large
file reads
Added loadstart handler to show 'Uploading...' spinner as soon as
upload begins, plus fallback label when lengthComputable is false
(shows bytes uploaded even without percentage).
Uploads already logged start, every-1-GiB progress, and completion.
Downloads only logged start — now also log:
- Completion with file size (Download complete: file.7z (1.9 GiB))
- Failure with wget exit code
- Periodic progress every ~1 GiB with speed and ETA
Both frontend and backend now write rotating log files to
/mnt/converter/logs/ (shared between host and LXC):
/mnt/converter/logs/vm-bench.log (frontend)
/mnt/converter/logs/vm-bench-backend.log (backend)
- RotatingFileHandler: 10 MB per file, 5 backups
- Console handler still writes to systemd journal
- Logs/ directory is gitignored and auto-created on startup
- Install script creates logs/ directory
Root cause: innerHTML does not execute <script> tags in modern browsers.
The _analysis.html and polling.html fragments had inline <script> blocks
that were silently dropped, causing:
- Confirm form's submitJob() undefined → form submitted as normal GET
back to '/' (user saw 'New Conversion Session' instead of polling)
- Polling page's poll() never started → stuck on 'Waiting for backend...'
Fix:
- Stripped all <script> tags from _analysis.html and polling.html
- Moved all JS logic into index.html (executed on page load)
- initConfirmForm() attaches submit/change listeners after analysis HTML
is injected via innerHTML
- initPolling() attaches poll timer + reuse button handlers after
polling fragment is injected
- Polling fragment replaces step1/analysis content while keeping
base.html header/footer intact
- Reuse buttons now use onclick attached via JS (not inline)
