How to open .VHDX files in virtualbox?

I used disk2vhd by microsoft so I tried to create a new virtualbox using it and I got this error

Could not open the medium 'C:\Users\user\Documents\Virtual Box Images\win7vir.VHDX'.

Just uncheck "Make VHDX" when creating the image in Disk2vhd. Virtual Box doesn't support the .VHDX format.

Short answer: use the powershell commandlet to convert the VHDX to VHD. AFAIK it requires hyperv or one of it's variants to be installed to have the convert-vhd commandlet available.

Convert-VHD –Path c:\test\MY-VM.vhdx –DestinationPath c:\test\MY-NEW-VM.vhd

VirtualBox since 4.2 changelog says support added for VHDX "Storage: added readonly support for VHDX images".

On the GUI of VirtualBOX when selecting the disk image to attach to a virtual machine, there is an option to choose a new virtual disk or one that exists.

If you choose to use one that exists, on the combo box there is an option for VHDX, but any time you try it tell you file format is not supported.

Why is that vhdx option there? Just to confuse users?

It seems that VirtualBox in in pre-state of implemented vhdx support, but some parts has arrived at user side while they are not really implemented.

At least till version 5.1.22
