Step 7:

Monitor and troubleshoot

​
View Logs

From the Web Interface:
  1. Open VMM dashboard at http://localhost:9080
  2. Click on your deployment
  3. Go to the “Logs” tab for real-time logs
From the CLI: 
# Stream logs in real-time
python3 vmm-cli.py --url http://localhost:8080 logs <vm-id> --follow

# Get last 100 lines
python3 vmm-cli.py --url http://localhost:8080 logs <vm-id> --lines 100
Direct HTTP API: 
curl 'http://<app-id>.app.example.com:9090/logs/<container_name>?follow=true&text=true&timestamps=true'

​
Check Application Status

# List all VMs and their status
python3 vmm-cli.py --url http://localhost:8080 lsvm --verbose

# List available images
python3 vmm-cli.py --url http://localhost:8080 lsimage

​
VM Management

# Start a VM
python3 vmm-cli.py --url http://localhost:8080 start <vm-id>

# Stop a VM
python3 vmm-cli.py --url http://localhost:8080 stop <vm-id>

# Remove a VM
python3 vmm-cli.py --url http://localhost:8080 remove <vm-id>

​
Common Issues & Solutions

​
Application fails to start

# Check VM logs for errors
python3 vmm-cli.py --url http://localhost:8080 logs <vm-id>

# Verify VM status
python3 vmm-cli.py --url http://localhost:8080 lsvm -v

​
Cannot access application URL

# Check if VM is running
python3 vmm-cli.py --url http://localhost:8080 lsvm

# Test connectivity
curl -I https://<app-id>.example.com

# Check gateway VM logs (find gateway VM ID first)
python3 vmm-cli.py --url http://localhost:8080 logs <gateway-vm-id> --follow

​
Attestation verification fails

  1. Ensure the CVM is fully initialized
  2. Verify TDX is enabled on your hardware
  3. Check app endpoint is accessible via Unix socket
