VirtualBox error message
By Matthew Nawrocki
So you just finished an operating system install within VirtualBox that you plan to use for testing purposes. After setting up the virtual machine, you get the guest operating system booted up and you mount an ISO image to the virtual disc drive for further examination. Meanwhile, it would seem prudent for you to create a snapshot of your virtual machine (VM) in the exact state it is in, should something go wrong. Once a VM snapshot is made within VirtualBox, you turn the VM off and delete the ISO, knowing that it no longer serves a purpose and you want to save disk space. Unfortunately, you get an error message the next time you fire up VirtualBox.
