  • Interface Binding: Automatic binding of TAP to bridge
  • Network Cleanup: Error-safe cleanup of network resources
  • Cross-Platform Networking: Support for both Linux and macOS network stacks

Platform Support

  • Linux Support: Full support with KVM acceleration
  • macOS Support: Full support with HVF (Hypervisor.framework) acceleration
  • Hardware Acceleration Detection: Automatic detection and fallback
  • Display Configuration: Platform-specific display settings (SDL/GTK)

Storage

  • Automated Disk Creation: qcow2 disk image creation with configurable sizes
  • Thin Provisioning: Efficient disk space usage
  • Image Compression: tar.gz compression for efficient storage and transfer

Scripts and Components

Core Scripts

  • run.sh (171 lines): Main execution script with complete VM lifecycle

Network Management (8 scripts)

  • create_network.sh: Complete network stack setup
  • create_bridge.sh: Bridge creation with IP configuration
  • create_and_get_bridge.sh: Bridge creation with name return
  • create_and_get_tap.sh: TAP interface creation with name return
  • bind_interfaces_to_bridge.sh: Interface binding utility
  • delete_bridge.sh: Safe bridge removal
  • qemu-ifup: TAP interface up script
  • qemu-ifdown: TAP interface down script

Disk Management

  • create_disk.sh: qcow2 disk creation with size configuration

Dependencies (4 scripts)

  • create_dependencies.sh: Setup TAP-related dependencies
  • delete_dependencies.sh: Cleanup TAP dependencies
  • get_dependencies.sh: List TAP dependencies
  • create_script_path_script.sh: Generate dependency scripts

Utilities (7 scripts)

  • get_acceleration.sh: Detect KVM/HVF hardware acceleration
  • get_display.sh: Detect optimal display type (SDL/GTK)
  • get_machine_log_name.sh: Generate log filenames
  • get_running_machines_count.sh: Count active VMs
  • is_macos.sh: Platform detection
  • fail.sh: Error exit
  • fail_and_cleanup.sh: Error exit with network cleanup

Testing

Automated Test Suite

  • Unit Tests: 45+ tests covering all core scripts
  • Integration Tests: End-to-end workflow testing
  • Network Tests: Bridge and TAP interface testing
  • Error Handling Tests: Cleanup and error recovery testing
  • Platform Tests: Linux and macOS compatibility testing

Test coverage:

  • Core scripts: 100%
  • Network management: 100%
  • Disk management: 100%
  • Utilities: 100%
  • Overall: 100% test coverage with 100% success rate

Configuration Examples

  • image_location.settings: Template for image cache path
  • image_provider.settings: Template for remote server URL
  • image_sync.sh: Template for rsync-based synchronization

Bug Fixes

  • Fixed TAP interface cleanup on QEMU startup failure
  • Fixed bridge creation race conditions
  • Improved error handling throughout all scripts
  • Fixed disk size configuration in create_disk.sh
  • Corrected display detection for headless systems

Performance Improvements

  • Optimized image download with resume capability
  • Improved compression speed with parallel processing
  • Reduced network setup time with caching
  • Better resource cleanup for faster restart times

Breaking Changes

Configuration Files Required

Previous versions could run without configuration files. Version 1.0.0 requires:

  • image_location.settings
  • image_provider.settings
  • image_sync.sh (for publishing only)

Migration: Copy examples from Examples/ directory and customize.

Sudo Required for Network Setup

Previous versions attempted network setup without sudo. Version 1.0.0 requires sudo for TAP/bridge configuration.

Migration: Run run.sh with sudo or configure sudoers for specific commands.

Disk Location Change

Previous versions stored disks in machine directory root. Version 1.0.0 stores disks in machine_name/disk.qcow2.

Migration: Existing disks must be moved into subdirectories matching machine names.

Deprecations

Old Configuration Format

  • Old: Single config.sh with all settings
  • New: Separate .settings files for each configuration aspect

Old configuration files will be supported until v2.0.0 but should be migrated.

Security Enhancements

  • Removed hardcoded credentials from examples
  • Added SSH key authentication examples
  • Improved permission handling for network operations
  • Added security best practices to documentation

Known Issues

  • Issue #1: Bridge persistence across reboots requires manual setup
    • Workaround: Re-run create_network.sh after reboot
  • Issue #2: Windows guests require manual VirtIO driver installation
    • Workaround: Download drivers from Fedora project
  • Issue #3: macOS HVF may require system preferences adjustment
    • Workaround: Enable virtualization in Security preferences

Upgrade Path from Proof-of-Concept

If you were using the previous proof-of-concept version:

  1. Backup existing VMs: Copy your machine directories
  2. Create configuration files: Use templates from Examples/
  3. Reorganize disks: Move disks into machine_name/disk.qcow2 structure
  4. Review sudo requirements: Configure sudo or run with elevated privileges
  5. Run tests: Execute test suite to verify your setup
  6. Update workflows: Follow new usage patterns from README.md
