Before we dive into the Hyper-V setup, you must understand what you are getting into. Xpenology is a grey-area software. Synology does not approve of it, and while it isn't technically "piracy" if you own a Synology license (debatable), it violates Synology’s EULA.
Hyper-V typically presents a virtual NIC based on the Synthetic Driver. TCRP usually includes the hv_netvsc driver. If the VM fails to obtain an IP address via DHCP, verify that the Virtual Switch is configured correctly and that no legacy network adapters are conflicting.

Xpenology DSM 7 on Hyper-V requires patience. The drivers aren't perfect, and the network card is a constant battle. But when it works—when you see that beautiful DSM 7 desktop booting on your $200 mini PC running Windows—it feels like magic.
Stay safe, back up your data, and happy virtualizing.

Running XPEnology DSM 7 on Microsoft Hyper-V allows you to leverage Synology’s powerful DiskStation Manager (DSM) within a Windows-based virtualization environment. While XPEnology is more commonly deployed bare-metal or on ESXi, modern automated loaders have made Hyper-V a viable option. Core Requirements
Hypervisor: Windows 10/11 Pro, Enterprise, or Education; or Windows Server with the Hyper-V role enabled.
Resources: Minimum 4GB RAM is recommended for DSM 7.x, especially when using modern loaders. xpenology dsm 7 hyperv
Bootloader: Modern automated loaders like Arc or RR (Redpill Recovery) are highly recommended for DSM 7 compatibility.
Network: A "Legacy Network Adapter" was historically required, but modern loaders often include the necessary Hyper-V integration drivers for standard virtual switches. Installation Overview
The process generally involves creating a Virtual Machine (VM) that treats a virtual disk as the bootloader USB. Prepare the Bootloader:
Download the latest .img or .vmdk from a modern loader project like Arc or RR.
Convert the image to a .vhdx format if necessary using tools like StarWind V2V Converter. Configure the Hyper-V VM:
Generation: Use Generation 1 for better compatibility with legacy bootloaders, though some modern loaders support Generation 2.
Disk Setup: Attach the bootloader .vhdx as an IDE controller (0:0) and ensure it is the first boot device.
Storage: Create additional virtual hard disks (VHDX) or use Discrete Device Assignment (DDA) to pass through a physical SATA/HBA controller for better performance. Boot and Build:
Start the VM and access the loader's web interface (usually by visiting the VM's IP address on port 7681).
Follow the automated prompts to select your Model (e.g., DS3622xs+ or DS918+) and DSM Version. If Synology Assistant doesn't find the NAS: Before
Once the loader builds the custom kernel, the VM will reboot into the standard Synology installation screen. Critical Tips for Success
Disk Controllers: If DSM cannot find your drives, ensure they are attached to a virtual SATA Controller in the VM settings, as the DSM kernel has strict requirements for storage controllers.
MAC Address: Note the virtual MAC address assigned by Hyper-V; you may need to input this into the loader configuration to ensure the Synology Assistant can discover the NAS.
Performance: For heavy workloads, passing through a physical disk or an entire HBA controller via DDA is significantly faster than using virtual disks stored on a Windows filesystem. Poor man's Synology NAS (using Proxmox and XPenology)
XPEnology DSM 7 Microsoft Hyper-V transforms your Windows-based server or workstation into a powerful Synology NAS alternative. This setup is popular in homelab environments for its speed and the ability to consolidate multiple services on a single physical machine. Why Run DSM 7 on Hyper-V? Hardware Consolidation
: Run a Windows host for daily tasks or other VMs while having a fully functional Synology-like NAS running in the background. Testing Ground
: Use it as a sandbox to test DSM updates, new applications, or Docker configurations before deploying them to production hardware. Resource Efficiency
: XPEnology can potentially run faster on DIY hardware than on original Synology units, as it can leverage more powerful CPUs and larger amounts of RAM. Legal Flexibility
: Since DSM is based on GPL-licensed software, third-party loaders like RedPill (TCRP) allow it to boot on standard x86 hardware. Core Requirements & Preparation

Running XPEnology (DSM 7) on Microsoft Hyper-V requires specific bootloaders to overcome hardware compatibility hurdles. While Hyper-V is often more challenging than ESXi or Proxmox for XPEnology, modern loaders like ARC and RR (Redpill Recovery) have made the process much smoother. Prerequisites Hyper-V Role: Enabled on Windows 10/11 or Windows Server.
Loader Image: Download the latest ARC or RR loader (vmdk or vhdx format) from the XPEnology Community.
Virtual Switch: An External Virtual Switch configured in Hyper-V Manager to allow the VM to get a local IP address from your router. Step 1: Create the Virtual Machine Open Hyper-V Manager and select New > Virtual Machine.
Generation: Use Generation 1 (preferred for legacy bootloader compatibility in most guides).
Memory: Assign at least 2GB (2048MB) of RAM. Disable "Dynamic Memory" for better stability. Networking: Select your External Virtual Switch. Hard Disk: Choose "Attach a virtual hard disk later." Step 2: Configure Hardware & Storage Arc & RR ALMOST working on Hyper-v. Help with error message
XPEnology exists in a legal gray area. While the DSM software is free to download, Synology's EULA states it is intended for Synology hardware only. Using XPEnology is technically a breach of that agreement.
Navigate to Network Adapter. Hyper-V uses "Synthetic" adapters by default, which are faster but require specific driver support. Older XPEnology loaders (Juns Loader) required the Legacy Network Adapter.
In the world of network-attached storage (NAS), Synology is the gold standard. Their DiskStation Manager (DSM) operating system is sleek, powerful, and feature-rich. However, the hardware cost for a 4-bay or 6-bay Synology unit can be prohibitive for homelab enthusiasts or small businesses on a budget.
Enter Xpenology—a bootloader that allows you to install Synology’s DSM operating system on generic hardware. Combine this with Microsoft Hyper-V (available on Windows 10/11 Pro, Enterprise, and Windows Server), and you have a recipe for a high-performance, virtualized NAS that costs nothing but your time.
The burning question for 2024 is: Does Xpenology DSM 7 work on Hyper-V?
The short answer is yes, but with significant caveats. This article will walk you through everything you need to know: the risks, the compatibility issues, the step-by-step installation, and how to optimize DSM 7 on Hyper-V for reliability.
