Using Virtualbox, why can my guest (Win7) not see the full d

I need to extend my Windows7.vdi. I tried:

Code: Select all

$ VBoxManage modifyhd /mnt/data/VirtualBox/Windows7.vdi --resize 50000

but got:Progress state: VBOX_E_NOT_SUPPORTED - I read that this is due to fix file size but I know my file is dynamic. The file currently is 23.6GB in size but the Virtual Media Manager in VirtualBox tells me its "Virtual size" is 488.28GB but in Windows I can't see that space, under Disk Management I only see my C: drive to have a capacity of 24.90GB. What's the problem here? Oh yes the remaining space on my host disk is >65GB, that should not be the limit either, here.

Here's a screenshot of the Disk Management dialog in Windows next to the Virtual Media Manager from VirtualBox:

Snapshots?

Okay,

No, I do not have anyt snapshots but I only have one Windows7.vdi and I have two different VMs running from this image (one of them says Linked Base). I don't see the full disk size in either of the two machines, might that be the problem? In Virtual Media Manager it says "Differencing VDI" when I hover over the respective instance. How can I resolve this?

Linked clones use the same mechanism as snapshots, so the same caveats apply. Note that if you create VM-B, a linked clone of VM-A, then both A and B will thereafter use difference images relative to a now-frozen primary disk.
