🖥️ QEMU Windows VM in Docker with VNC Access

This project allows you to run a lightweight, isolated Windows virtual machine using QEMU inside a Docker container, with VNC remote desktop access. It is useful for testing, sandboxing, or serving GUI-based environments remotely.

---

📦 Features

• Full Windows VM with VirtIO drivers
• QEMU-based virtualization
• VNC access over configurable ports
• Parametric CPU, RAM, and Disk configurations
• Base QCOW2 image support for efficient disk usage
• Volume-based persistent disk
• Easy-to-use docker-compose deployment

---

⚙️ Requirements

• Docker
• Docker Compose
• Host system that supports KVM/QEMU (Linux recommended)

---

🚀 Getting Started

1. Clone the Repository

git clone https://github.com/cynegeirus/winbox-docker.git
cd winbox-docker

2. Prepare ISO Images

Place your Windows installation ISO and VirtIO ISO files into the iso/ directory:

iso/
├── os.iso         # Windows ISO
└── virtio.iso     # VirtIO drivers ISO

You can rename them if needed, just update the Dockerfile or main.sh accordingly.

---

🔧 Configuration

You can modify the following environment variables inside docker-compose.yml or .env:

environment:
  - CPU=2              # Number of CPU cores
  - RAM=4G        # RAM in megabytes
  - DISK_SIZE=20G      # Virtual disk size
  - VNC_PORT=5903      # VNC port to expose

---

🧪 First-Time Setup

To build and start the virtual machine:

docker-compose up -d --build

The first run will create the disk image and start the Windows installation.

---

🖥️ Access the VM

Use any VNC client to connect:

Host: <your-host-ip>
Port: <VNC_PORT> (default 5901)

---

💾 Persistent Storage

The virtual machine disk is stored in a named Docker volume or host path (/machines/ inside the container). You can mount it from the host or export it for backup.

---

🧠 Advanced Features

• Base Image Layering: Use qemu-img with -b base.qcow2 to create differential VM disks.
• Multiple VMs: Scale up using docker-compose --scale machine=n with different ports.

⚠️ Warnings

• Do not mount the same QCOW2 disk in multiple VMs for read-write.
• Base QCOW2 files must remain unchanged once overlay disks are created.
• Ensure host system supports KVM and nested virtualization.
