Python SDK Integration (v2.0)

Option 1: Using the Python SDK (Recommended)

from hypersdk import HyperSDK

# Initialize client
client = HyperSDK("http://localhost:8080")

# Simple export
result = client.export_vm(
    vm_path="/datacenter/vm/my-vm",
    output_path="/exports",
    format="ova"
)
print(f"Job submitted: {result['job_id']}")

# Incremental backup with CBT
savings = client.enable_cbt("/datacenter/vm/my-vm")
print(f"Expected savings: {savings['savings_percent']}%")

result = client.submit_incremental_export(
    vm_path="/datacenter/vm/my-vm",
    output_path="/backups"
)
print(f"Incremental backup started: {result['job_id']}")

# Cost estimation
estimate = client.estimate_cost(
    storage_gb=500,
    provider="s3",
    storage_class="standard",
    duration_days=365
)
print(f"Annual cost: ${estimate['total_cost']:.2f}")

# Compare cloud providers
comparison = client.compare_providers(
    storage_gb=500,
    duration_days=365
)
for provider in comparison['providers']:
    print(f"{provider['name']}: ${provider['total_cost']:.2f}/year")

Option 2: Direct REST API

import requests
import time

BASE_URL = "http://localhost:8080"

# Submit job
response = requests.post(f"{BASE_URL}/jobs/submit", json={
    "name": "python-export",
    "vm_path": "/datacenter/vm/my-vm",
    "output_path": "/tmp/export",
    "options": {
        "parallel_downloads": 4,
        "remove_cdrom": True
    }
})

job_id = response.json()["job_ids"][0]
print(f"Job submitted: {job_id}")

# Poll for completion
while True:
    response = requests.post(f"{BASE_URL}/jobs/query",
        json={"job_ids": [job_id]})

    job = response.json()["jobs"][0]
    status = job["status"]

    if status == "completed":
        print(f"✅ Export completed: {job['result']['ovf_path']}")
        break
    elif status == "failed":
        print(f"❌ Export failed: {job.get('error')}")
        break

    if job.get("progress"):
        progress = job["progress"]
        print(f"⏳ {progress['phase']}: {progress['percent_complete']:.1f}%")

    time.sleep(5)

See Python SDK documentation and examples for more details.

Technology Stack

Language: Go 1.24+
vSphere SDK: govmomi v0.52.0
AWS SDK: AWS SDK for Go v2
Azure SDK: Azure SDK for Go
GCP SDK: Google Cloud Client Libraries
Hyper-V: PowerShell via WinRM
Libvirt: virsh command-line integration
Terminal UI: pterm v0.12.82
Progress Bars: progressbar v3.19.0
Config: YAML (gopkg.in/yaml.v3)
HTTP Server: Go standard library
React Dashboard: React 18 + TypeScript + Vite + Recharts
Legacy Dashboard: Pure HTML/CSS/JavaScript

Concurrency Model

Goroutines for job execution (not threads/forks)
Channels for communication
Mutexes for shared state protection
Worker pools for parallel downloads
Context for cancellation and timeouts

📊 Performance

Connection Time: ~1-2 seconds
VM Discovery: ~1 second (200+ VMs)
Download Speed: Network-limited
Memory Usage: Low (streaming downloads)
Concurrent Jobs: Unlimited (goroutine-based)
API Response: < 50ms

🔒 Security

Disable Web Dashboard (API-Only Mode)

For security-conscious deployments, embedded systems, or pure automation use cases, you can disable the web dashboard:

# Option 1: CLI flag
./hypervisord --disable-web

# Option 2: Config file
# config.yaml
web:
  disabled: true

Benefits:

Reduced attack surface (no web UI)
Lower resource usage
Perfect for headless/embedded systems
API-only automation environments

When disabled, the daemon runs in API-only mode with all 51+ REST endpoints still available via CLI or scripts.

Systemd Hardening

The systemd service includes security hardening:

NoNewPrivileges=true
PrivateTmp=true
ProtectSystem=strict
ProtectHome=true
ProtectKernelTunables=true

Credentials

Store credentials in config file: /etc/hypervisord/config.yaml
Protect config file: chmod 600 /etc/hypervisord/config.yaml
Or use environment variables for temporary use
Never commit credentials to git
