VMDK (Virtual Machine Disk) and VHD (Virtual Hard Disk) are common virtual disk formats used in virtualization. VMDK is used by VMware hypervisors while VHD is used by Microsoft’s Hyper-V. There are situations where you need to convert a VMDK disk image to VHD format, for example when migrating virtual machines from VMware to Hyper-V.
This article will provide a step-by-step guide on how to quickly convert VMDK to VHD in just 5 minutes using the free Microsoft Virtual Machine Converter (MVMC).
Reasons for Converting VMDK to VHD
Here are some common reasons you may need to convert VMDK to VHD:
- Migrating from VMware to Hyper-V: If you want to migrate your VMware virtual machines to Hyper-V, you’ll need to convert the VMDK disks to VHD.
- Consolidating virtualization platforms: Organizations often standardize on a single virtualization platform. Converting to a common disk format makes consolidation easier.
- Importing disks to Azure: Azure supports importing VHD disks to use as VM images. So converting from VMDK allows importing VMware disks to Azure.
- Corrupt VMDK recovery: If your VMDK disks get corrupted, converting them to VHD is an option for recovery.
Microsoft Virtual Machine Converter (MVMC)
The Microsoft Virtual Machine Converter (MVMC) is a free tool from Microsoft that allows converting VM formats and disks including VMDK to VHD.
Key features of MVMC include:
- Supports offline conversion of VMs and disks including VMDK to VHD/VHDX.
- Optimized for large scale migration scenarios.
- Built-in PowerShell module for scripting and automation.
- Supports conversion of physical machines to Hyper-V using disk images.
MVMC meets the core requirement of easily converting between VMDK and VHD. It also provides automation capabilities for large scale workload migrations.
Step-by-Step Guide to Convert VMDK to VHD
Follow these simple steps to convert a VMDK disk image to VHD using MVMC:
- Download and install MVMC from the Microsoft Download Center.
- Locate your VMDK file you want to convert. Make sure the VM is powered off.
- Open PowerShell as Administrator and enter the following command:
ConvertTo-MvmcVirtualHardDisk -SourceLiteralPath C:\VMs\myvm\mydisk.vmdk -VhdType DynamicHardDiskReplace the path with your actual VMDK location.
- The conversion process will now start. Wait for it to complete.
- You will find the converted VHD disk in the same folder as the source VMDK.
The key parameters:
-SourceLiteralPath– Specifies VMDK path
-VhdType– Choose between dynamic or fixed VHD
That’s it! The VMDK disk is now converted to VHD quickly within 5 minutes. You can now use this VHD in Hyper-V or import to Azure.
Conversion Automation and Advanced Usage
MVMC provides a PowerShell module for automation and advanced usage scenarios:
- Script the conversion process for multiple VMDK files
- Customize naming convention for output VHDs
- Automate migration workflows from VMware to Hyper-V
- Schedule conversions using Windows Task Scheduler
The Microsoft Virtual Machine Converter makes it easy to convert VMDK to VHD in just a few simple steps. With its automation capabilities, it can handle large and complex migration projects from VMware to Hyper-V or Azure.
Whether you just need to convert a few VMDK disks or orchestrate the migration for hundreds of VMs, MVMC has you covered. So go ahead and take advantage of this free tool from Microsoft!
