Converting VirtualBox to Hyper-V: A Step-by-Step Guide

As businesses or individual users increasingly shift towards Hyper-V for its robust performance and scalability, many find themselves needing to convert their existing VirtualBox VMs to Hyper-V. If you’re one such user, you’re in the right place. I’m Tracy, and I’ll guide you through the process of converting a VirtualBox virtual machine to Hyper-V.

Prerequisites Before Conversion

Before starting the actual conversion process, ensure that you have the following:

– A VirtualBox VM that you want to convert.
– A Windows machine with Hyper-V enabled.
– Enough storage space for the converted virtual machine.
– The latest version of Microsoft Virtual Machine Converter (MVMC) installed.

Understanding the Conversion Process

The conversion consists of two major steps: exporting the VirtualBox VM to an OVF or OVA file, and then converting that file to a Hyper-V compatible format.

Step 1: Exporting VirtualBox VM to OVF/OVA

1. Open VirtualBox and select the VM you want to export.
2. Go to “File” > “Export Appliance.”
3. Follow the on-screen wizard, choose a destination for the export, and select the OVF or OVA file format.

Step 2: Converting OVF/OVA to Hyper-V

Options for conversion include using Microsoft Virtual Machine Converter or a third-party tool, manual conversion using PowerShell, or other software. In this guide, we’ll use MVMC for its simplicity and support from Microsoft.

1. Open PowerShell as an administrator.
2. Execute the following command to start the conversion process:

Import-Module ‘C:\Program Files\Microsoft Virtual Machine Converter\MvmcCmdlet.psd1’
ConvertTo-MvmcVirtualHardDisk -SourceLiteralPath ‘C:\path-to-your-ovf\vm-disk1.vmdk’ -DestinationLiteralPath ‘C:\path-to-converted-vhd\vm-disk1.vhd’ -VHDType DynamicHardDisk -VHDFormat Vhd

Replace the paths with the correct ones for your OVF file and desired destination.

Post-Conversion Steps

Once the conversion is completed, a VHD or VHDX file will be created, which can be used in Hyper-V. Add this converted disk to a new Hyper-V VM:

1. Open the Hyper-V Manager.
2. Click “New” > “Virtual Machine” to create a new VM.
3. Attach the converted disk when prompted for a hard drive.

Common Conversion Problems and Solutions

Here’s a quick table to aid you should you encounter any issues:

Problem Possible Solution
OVF/OVA Export Fails Ensure there are no snapshots and the VM is powered off in VirtualBox.
Conversion Process Errors Check MVMC installation, run PowerShell as administrator and verify file paths.
Imported VM Does Not Boot Verify integration services are installed and that you’ve selected the correct generation for the VM in Hyper-V.

Frequently Asked Questions (FAQ)

Can I convert a VM while it is running?

No, the VM needs to be powered off in order to export and convert it safely.

Does this process apply to any version of VirtualBox or Hyper-V?

This general process applies across various versions, but ensure you are using versions that are compatible with MVMC or any other tools you choose to employ.

Are there any alternatives to MVMC?

Yes, there are third-party tools like StarWind V2V Converter which can also be used for the conversion.

Can I convert from VHD to VHDX or vice versa?

Yes, Hyper-V Manager allows you to convert between VHD and VHDX formats after the initial conversion.


By following these instructions, you should be able to convert your VirtualBox VMs to Hyper-V format without too much hassle. Remember, like with any tech procedure, double-checking each step and having a backup before starting any conversion process is crucial. If you run into any challenges, refer to the FAQ or reach out to online forums and the broader community for additional assistance. Good luck with your conversion!
