Overview

This development plan outlines the implementation of a production-ready MicroVM sandbox system using Cloud Hypervisor and Python with support for both Linux and Windows guest operating systems. The system provides hardware-level isolation through MicroVMs while maintaining lightweight resource usage.

Architecture Selection Rationale

Cloud Hypervisor + Python

Why Cloud Hypervisor?

  • Modern Rust-based VMM with excellent performance
  • Native support for both Linux and Windows guests
  • Hardware virtualization through MicroVMs
  • Strong isolation boundaries with lightweight resource usage
  • Active development and Intel backing
  • REST API for programmatic management

Why Python?

  • Different from Go (Arrakis language) - ensuring independent implementation
  • Excellent ecosystem for system automation
  • Good for rapid prototyping and iteration
  • Strong JSON/HTTP libraries
  • Rich async/await support for concurrent VM management
  • Extensive testing and deployment tooling
