Pre allocate all required size to a new macchine

Hi

I am trying to load a disk image to a new VM

After creating the machine (without installing the OS) I boot the machine into a boot environment containing DriveImage XML

The image size was created from a 100GB disk.

But even though I set the disk size of the new machine to (max) 100G the actual size of the machine is only 12G

For that reason, I guess, trying to restore the image onto the new VM fail, as the actual disk size(12G)  is less than the image size (100G)

Is there a possibility to make the empty newly created VM size holds the full max size - 100G?
