If the DSM web interface does not appear after a reboot:
DSM is based on Linux. Hyper-V’s default "Synthetic Network Adapter" requires the Linux Integration Services (LIS) to work. The Xpenology bootloaders (RedPill) often do not include the Hyper-V LIS drivers natively for DSM 7. You will likely need to use the Legacy Network Adapter (which limits you to 100 Mbps—unacceptable for a NAS).
The Workaround: You must use a virtio-net driver conversion or specific RedPill builds compiled with the hv_sock and hyperv_keyboard modules. Fortunately, the community has released "Hyper-V friendly" images for DSM 7.2.
Common problems include:
Running Xpenology with DSM 7 on Microsoft Hyper-V is a fascinating technical challenge. When it works, you get the beautiful Synology interface, Btrfs snapshots, Active Backup for Business, and Synology Drive—all on a Windows machine that’s already running 24/7.
But the asterisk is large. Driver issues, sluggish performance, and the threat of DSM updates breaking everything make this unsuitable for production. For homelab enthusiasts who enjoy tinkering and don’t mind occasional data loss from snapshots, it’s a rewarding weekend project.
Final verdict:
Cause: Hyper-V presented an IDE drive instead of SATA/SCSI. Fix: Remove the IDE controller in VM settings. Add a SCSI controller, then add a Hard Drive under that controller.

XPEnology DSM 7 is a technically complex task because Synology's DSM does not natively support Hyper-V's drivers. While older versions (DSM 5.2) were easier to virtualize, DSM 6 and 7 require specific modern bootloaders like RedPill (RR) to bridge this compatibility gap. XPEnology Community Key Requirements & Limitations Virtual Hardware : You must generally use Generation 1 virtual machines. Storage Controllers
: Hyper-V's lack of support for virtual SATA disks is a major hurdle. Standard IDE or SCSI virtual disks often fail to show up in DSM; the most reliable workaround is using Discrete Device Assignment (DDA)

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.
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 If the DSM web interface does not appear after a reboot:
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.
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. DSM is based on Linux
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
Installing DSM 7 on Hyper-V is more complex than on physical hardware due to specific virtualization constraints:

The Redpill community is struggling to keep up. Most experts predict that Xpenology on Hyper-V will die by 2026, as Synology continues to lock down its OS. If you install DSM 7 today, do not expect to update to DSM 8.
