Ubuntu Sandbox VM - One-Click Launcher

🚀 Automatically downloads, verifies, and launches Ubuntu 24.04 Desktop in a disposable QEMU virtual machine with zero configuration.

✨ Features

• ✅ Automatic ISO management - Downloads and caches Ubuntu 24.04 Desktop ISO
• ✅ Cryptographic verification - SHA256 checksum validation against official Ubuntu sources
• ✅ Hardware acceleration - Automatic KVM detection and usage
• ✅ Temporary disk - 32GB qcow2 image auto-deleted on exit (no traces left)
• ✅ Smart resource allocation - Detects and allocates optimal CPU/RAM (50% of host, max 8GB)
• ✅ Resume support - Interrupted downloads can be resumed
• ✅ Network ready - VM has internet access via user-mode networking
• ✅ True disposable - Every launch is a fresh environment

🔒 Security Note

This provides good isolation for testing and quick Dev experimentation, but is not a maximum-security sandbox. The VM has network access and shares the display server. Suitable for testing unknown software and preventing accidental host damage, but not recommended for analyzing malicious code.

📦 Installation

Method 1: .deb Package (Recommended)

# Download the package
wget https://github.com/globalcve/oneclick-ubuntu-vm-sandbox/releases/download/1.00/sandbox-vm_1.0.deb

# Install it
sudo dpkg -i sandbox-vm_1.0.deb

# Fix dependencies if needed
sudo apt install -f

Method 2: Direct Script

# Download the script
wget https://raw.githubusercontent.com/globalcve/oneclick-ubuntu-vm-sandbox/main/sandbox.sh

# Make it executable
chmod +x sandbox.sh

# Move to PATH (optional)
sudo mv sandbox.sh /usr/local/bin/sandbox

🚀 Usage

Simply run:

sandbox

On first run, it will:

1. Download Ubuntu 24.04 Desktop ISO (~6GB)
2. Verify cryptographic checksums
3. Cache the ISO for future use
4. Launch the VM

Subsequent runs use the cached ISO and launch instantly.

💻 System Requirements

• OS: Ubuntu/Debian-based Linux distribution
• RAM: 4GB+ recommended (VM uses 50% of host RAM, max 8GB)
• Disk: 6GB free space for ISO cache
• CPU: Multi-core recommended (VM uses up to 4 cores)
• Optional: /dev/kvm for hardware acceleration (10x faster)

📦 Dependencies

The following packages are required (auto-installed with .deb):

• qemu-system-x86 - QEMU x86 system emulator
• qemu-utils - QEMU disk image utilities
• curl - Download tool
• coreutils - SHA256 checksums
