```
|
||||
|
||||
### QEMU not found
|
||||
- Ensure QEMU is installed and in your PATH
|
||||
- Windows: Add QEMU installation directory to PATH
|
||||
### Cluster Management
|
||||
```bash
|
||||
# Check cluster status
|
||||
qemu-vm> cluster status
|
||||
|
||||
### Permission denied (Linux)
|
||||
- Add your user to kvm and libvirt groups
|
||||
- Restart your session after adding groups
|
||||
# List all nodes
|
||||
qemu-vm> nodes list
|
||||
|
||||
### Network bridge not found
|
||||
- Create the bridge: `sudo virsh net-start default`
|
||||
- Or use user networking: change bridge to "user" in VM config
|
||||
# View cluster topology
|
||||
qemu-vm> cluster info
|
||||
```
|
||||
|
||||
### Build issues

# Run diagnosis
|
||||
qemu-vm> diagnose
|
||||
|
||||
# Check common issues:
|
||||
# 1. Hardware virtualization enabled in BIOS
|
||||
# 2. QEMU in PATH
|
||||
# 3. Disk images exist
|
||||
# 4. Sufficient memory/CPU
|
||||
```
|
||||
|
||||
### P2P Connection Issues
|
||||
```bash
|
||||
# Check node status
|
||||
qemu-vm> cluster status

## 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
|
||||
2. **Core Layer** (`QemuVmManager.Core`): Handles QEMU command generation and process management
|
||||
3. **Services Layer** (`QemuVmManager.Services`): Provides high-level VM management operations
|
||||
4. **Console Layer** (`QemuVmManager.Console`): User interface and command processing
|
||||
1. **KVM** (Linux) - Native virtualization
|
||||
2. **Hyper-V/WHPX** (Windows) - Hardware acceleration
|
||||
3. **HAXM** (Windows/macOS) - Intel acceleration
|
||||
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
|
||||
- **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
|
||||
## 🚨 Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
1. **QEMU not found**: Ensure QEMU is installed and in your PATH
|
||||
2. **Permission denied**: Run with appropriate permissions for KVM/bridge access
|
||||
3. **Network bridge not found**: Create the bridge interface (e.g., `virbr0`)
|
||||
4. **Disk file not found**: Ensure disk paths are correct and accessible
|
||||
#### VM Won't Start
|
||||
```bash
|
||||
qemu-vm> diagnose
|
||||
```
|
||||
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
