## Architecture ## 🔧 Advanced Features
The application follows a layered architecture: ### Hardware Acceleration Detection
The system automatically detects and prioritizes available virtualization technologies:
1. **Models Layer** (`QemuVmManager.Models`): Contains data structures for VM configuration and status 1. **KVM** (Linux) - Native virtualization
2. **Core Layer** (`QemuVmManager.Core`): Handles QEMU command generation and process management 2. **Hyper-V/WHPX** (Windows) - Hardware acceleration
3. **Services Layer** (`QemuVmManager.Services`): Provides high-level VM management operations 3. **HAXM** (Windows/macOS) - Intel acceleration
4. **Console Layer** (`QemuVmManager.Console`): User interface and command processing 4. **HVF** (macOS) - Apple Hypervisor
5. **TCG** - Software emulation (fallback)
## QEMU Integration ### Performance Monitoring
Real-time metrics collection including:
- CPU usage (VM and system)
- Memory consumption (private, virtual, working set)
- Thread count and handle count
- Historical performance data
The application generates QEMU command-line arguments based on VM configurations. Key features: ### UPnP Integration
- Automatic router discovery
- External IP address detection
- Port mapping management
- NAT traversal support
- **KVM Acceleration**: Automatically enables KVM when available ## 🚨 Troubleshooting
- **VirtIO Support**: Uses VirtIO devices for better performance
- **Network Bridging**: Supports bridge networking
- **SPICE Support**: Optional SPICE remote desktop
- **Shared Folders**: 9P filesystem sharing
- **Advanced Features**: Audio, USB, balloon driver, RNG
## Troubleshooting
### Common Issues ### Common Issues
1. **QEMU not found**: Ensure QEMU is installed and in your PATH #### VM Won't Start
2. **Permission denied**: Run with appropriate permissions for KVM/bridge access ```bash
3. **Network bridge not found**: Create the bridge interface (e.g., `virbr0`) qemu-vm> diagnose
4. **Disk file not found**: Ensure disk paths are correct and accessible ```
Check for:
- Hardware virtualization enabled in BIOS
- QEMU installation and PATH
- Disk image existence and permissions
- Available memory and CPU resources
### Debug Mode #### P2P Connection Issues
- Verify firewall settings
- Check network connectivity between nodes
- Ensure discovery ports are open
- Review node configuration
To see the generated QEMU commands, you can modify the `QemuProcessManager.cs` to log the command before execution. #### Performance Issues
- Enable hardware acceleration
- Use virtio drivers when available
- Monitor resource usage
- Consider VM migration to less loaded nodes
