Xpenology Dsm 7 Hyperv < HD >

Hyper-V presents virtual disks as .vhdx files on an IDE or SCSI controller. DSM 7 prefers native SATA. You will need to configure your bootloader to treat the Hyper-V virtual SCSI controller as a standard SATA controller.

Experienced Xpenology users usually flock to VMware ESXi or Proxmox because they offer better SATA controller passthrough. Microsoft Hyper-V, by contrast, abstracts the hardware significantly.

Important: Do not use the "IDE" controller for data drives. Use the "SCSI" controller in Hyper-V and map it to SATA inside DSM (RedPill handles this).

Go to Control Panel → Update & Restore → Set to "Notify only" or disable. Never click "Update Now". To update, you must rebuild the ARPL loader manually. xpenology dsm 7 hyperv

This is the most common point of failure. Synology DSM requires the sd driver naming convention (e.g., /dev/sda). By default, Hyper-V Generation 1 VMs use IDE controllers for the boot drive.

Cause: Hyper-V’s default network adapter doesn’t support the e1000e driver DSM 7 uses. Fix: Hyper-V presents virtual disks as

If the physical host has an Intel CPU with QuickSync capabilities, it is possible to pass this through to the VM for hardware transcoding (e.g., in Plex or Synology Photos).

Cause: The watchdog kernel thread stuck in a loop. Fix: Experienced Xpenology users usually flock to VMware ESXi
