resize Disk-Image

1. Create new Disk-Image with given size (–remember does not always work, don't know why): 

   VBoxManage createhd –-filename NewDisk.vmdk --size 30000 --remember

2. Clone old Disk-Image in the new one: 

   VBoxManage clonehd OldDisk.vmdk NewDisk.vmdk --existing

3. Replace the old image with the new one: 

   VBoxManage modifyvm "My Virtual Machine" --hda none
   VBoxManage modifyvm "My Virtual Machine" --hda NewDisk.vmdk

(has never worked, use GUI instead)
