Add a Proxmox VE importer that reads the /api2/json REST API with a read-only
API token and drops hosts (proxmox), VMs (vm) and LXC containers (lxc) onto the
canvas as typed nodes with run state and hardware specs (vCPU/RAM/disk).
- Backend: proxmox_service (httpx) + proxmox routes (test-connection, import,
import-pending, config). Two-tier dedupe — merge onto an existing scanned node
by IP, else synthetic pve-{host}-{vmid} identity. Update-in-place, never
deletes. Host->guest rendered as a 'virtual' edge via the pending-link flow.
- Security: token is env-only (PROXMOX_TOKEN_*), never written to disk by the
app, never returned by any endpoint; errors are credential-sanitized.
- Auto-sync: optional scheduled re-import into pending (APScheduler job).
- PendingDevice.properties carries specs through approve (+ migration).
- Frontend: ProxmoxImportModal, sidebar entry, pending inventory source filter,
Settings auto-sync section, proxmoxApi client.
- Docs: docs/proxmox-import.md, README + FEATURES sections, .env.example keys.
- Tests: backend service/router/scheduler, frontend modal/client/pending.
ha-relevant: maybe
The previous parser read `data.routes` which is just an echo of the
`routes` request flag (a boolean). On real brokers this caused
`TypeError: 'bool' object is not iterable` and 500s during /import.
- Rewrite parse_networkmap to read data.value.nodes + data.value.links
with fallback to data.{nodes,links} for legacy variants
- Defensive: drop links to unknown nodes, propagate lqi from link to
target node, extract model/vendor from definition block
- Bump networkmap timeout 10s -> 180s (large meshes are slow)
- Tests: rewrite fixture builders + sample payload to real Z2M shape;
add cases for legacy shape, routes:false echo (regression), malformed
list, link to unknown node, lqi propagation, definition extraction
- Update docs to mention 60s+ wait window
53 backend tests pass, mypy + ruff clean.
