cant resize the vdi storage of my windows 10 guest on an ubuntu host (Version 5.0.40_Ubuntu r115130)

Mehdi Esteghamatian

I am trying to resize vdi of my Windows 10 guest running on my Ubuntu laptop.

The VirtualBox is Version 5.0.40_Ubuntu r115130.

I just don't understand why I am getting the below error:

[email protected]:~/VirtualBox VMs/MyWindows10$ VBoxManage modifyhd NewVirtualDisk1.vdi --resize 50000

0%...

Progress state: VBOX_E_NOT_SUPPORTED

VBoxManage: error: Resize medium operation for this format is not implemented yet!

Thanks for any comments/clue.

Found it....I ran the below clone hd command .....

attached the clone version to the VM and now I can see the previously allocated/modified space showing up on  the windows guest....

[email protected]:~/VirtualBox VMs/MyWindows10$ VBoxManage clonehd NewVirtualDisk1.vdi NewVirtualDisk1.cloned.vdi

0%...

10%...20%...30%...40%...50%...60%...70%...80%...90%...100%

Clone medium created in format 'VDI'. UUID: 874b08b3-2f9f-48d6-9553-3414c7e9cd59

Can anybody tell me the rational behind this ....

thanks
