I initially created a dynamically expanding VirtualBox image, and have tried to increase its hard drive space: After that, I saw from the UI that it has increased to 16GB logical size:
Sadly, when I boot the image, I still get the initial size (e.g. when I use |

After increasing the size of the underlying device, you must as well increase the size of the file system and, if so, everything in-between (partitions, LVM stuff etc.).

But not after booting into that very system (that is, not from the disk) - just as you should never resize your partition, from which your system booted. So the solution is to download a bootable CD iso image like SystemRescueCD or Gparted live. Add it to your virtual machine (just in the menu you showed in your picture - select the "SATA Controller", click "Add CD/DVD Device" icon and then, on the right, browse for your iso file) and set to boot from that instead of the disk image (but do not remove the image of course). Once you've booted, run |
