az-scout plugin for AVS migration risk analysis from RVTools exports

az-scout-plugin-avs-rvtools-analyser

An az-scout plugin that analyses RVTools Excel exports to detect migration risks for Azure VMware Solution (AVS).

Ported from the standalone avs-rvtools-analyzer project — focused on migration risk analysis only.

Features

• 19 risk detection checks covering vUSB, risky disks, network switches, ESX versions, hardware versions, shared disks, clear-text passwords, Oracle VMs, Fault Tolerance, VMkernel networks, and more
• Infrastructure statistics — VM counts (on/off/suspended), total vCPUs, memory, provisioned & used storage, disk count, ESXi host count with average CPU/memory usage, datastore capacity/usage, and OS distribution
• Tabbed results UI — Migration Risks tab + Statistics tab, both populated from a single file upload (two parallel API calls)
• File upload UI with drag-and-drop, progress bar, risk summary cards, risk distribution gauge, and expandable risk detail cards with data tables
• Option to exclude powered-off VMs from both risk analysis and statistics
• Password redaction — clear-text passwords in annotations/snapshots are automatically redacted from results
• Per-risk CSV export and print / PDF support (both tabs printed together)
• AI recommendations — per-risk AI-powered guidance with remediation steps and references (requires AI to be enabled on the az-scout instance)
• MCP tools for programmatic analysis:
  • list_avs_migration_risks — list available risk checks
  • convert_rvtools_excel_to_json — convert a local RVTools file to compact JSON (only relevant sheets/columns, validated via vMetaData)
  • analyze_rvtools_json — run migration risk analysis on JSON data
  • analyze_rvtools_statistics — extract infrastructure statistics from JSON data

Risk Levels

Level	Meaning
Emergency	Critical security issue (e.g. clear-text passwords)
Blocking	Prevents migration entirely
Warning	Needs attention before migration
Info	Informational, no action required

Setup

# Install alongside az-scout
uv pip install az-scout-plugin-avs-rvtools-analyser

# Or install in dev mode from source
uv sync --group dev
uv pip install -e .

# Start az-scout — the plugin tab appears automatically
az-scout

Generate Test Data

Create a comprehensive RVTools Excel file with all 19 risk categories represented:

uv run python tools/create_test_data.py                      # → comprehensive_test_data.xlsx
uv run python tools/create_test_data.py -o /tmp/rvtools.xlsx  # custom output path

The generated file contains 12 sheets (vHost, vInfo, vDisk, vUSB, vSnapshot, vCD, vNetwork, vSC_VMK, dvPort, dvSwitch, vDatastore, vMetaData) with ~44 VMs covering every risk type: emergency (clear-text passwords), blocking (RDM disks, shared disks, high vCPU/memory, HW version, standard switches, vUSB), warning (snapshots, suspended VMs, CD-ROMs, VMkernel networks, non-Intel hosts, VMware Tools, Fault Tolerance, large storage, dvPort issues), and info (Oracle VMs, ESX versions).
