Convert VMWare to Hyper-V (vmdk to vhdx)

vmdk_vhdx.md

VMDK to VHDX

Follow steps:

• Download: http://download.microsoft.com/download/9/1/E/91E9F42C-3F1F-4AD9-92B7-8DD65DA3B0C2/mvmc_setup.msi (thanks @xavery)
• Open Powershell as administrator and run Import-Module 'C:\Program Files\Microsoft Virtual Machine Converter\MvmcCmdlet.psd1'
• And after ConvertTo-MvmcVirtualHardDisk -SourceLiteralPath d:\scratch\vmx\VM-disk1.vmdk -VhdType DynamicHardDisk -VhdFormat vhdx -destination c:\vm-disk1

If you counter following error:

ConvertTo-MvmcVirtualHardDisk : The entry 1 is not a supported disk database entry for the descriptor.

In my case it was entry 4

Follow these steps:

1. download and extract dsfok tools
2. use dsfo.exe "c:\temp\disk2.vmdk" 512 1024 descriptor1.txt to extract the descriptor
3. edit the descriptor file in Notepad++: comment the above mentioned line (as I added the extra single character (#) I also deleted one NULL character from the end to keep the file size of 1024 bytes (not sure if this is needed).
4. use dsfi.exe "c:\temp\disk2.vmdk" 512 1024 descriptor1.txt to inject the descriptor back into the VMDK
5. repeat these steps for the other disk (my VM has two .vmdk files)
6. reissue the ConvertTo-MvmcVirtualHardDisk command

This all looks very promising, did anyone ever write a script that automates this process? I‘d like to install Whonix in Hyper-V but didn’t get it to work so far

Does not work:

3.1 Command 1:

Import-Module 'G:\Tools\Microsoft Virtual Machine Converter\MvmcCmdlet.psd1'

3.2 Command 2:

ConvertTo-MvmcVirtualHardDisk -SourceLiteralPath "D:\Virtual Machines\Windows 11 (VM 4, Official, RAD Studio 11 Alexandria, Windows 11 Updated, Reactivated)\Windows 11 x64.vmdk" -VhdType DynamicHardDisk -VhdFormat vhdx -destination "G:\Virtual Machines\Windows 11 (VM 4, Official, RAD Studio 11 Alexandria, Windows 11 Updated, Reactivated, Converted to VHDX)\Windows 11 x64.vhdx"
