1) Open Prompt Dos session (with run as administrator)
2) Navigate to C:\Program Files\Oracle\VirtualBox folder (I use latest VirtualBox 5.1.26 version)
3) launch VBoxManage with this statement:
Code: Select all
C:\Program Files\Oracle\VirtualBox>vboxmanage modifymedium "C:\VirtualBox VMs\Windows 10-1703-en\Windows 10-1703-en.vdi" --resize 64
Code: Select all
0%...
Progress state: VBOX_E_NOT_SUPPORTED
VBoxManage.exe: error: Resize medium operation for this format is not implemented yet!
This currently works only for VDI and VHD formats, and only for the dynamically allocated variants, and can only be used to expand (not shrink) the capacity.
Then, why I get this error?
How to expand my VDI?
Thank!
