VirtualBox: Resize vdi

Assume the hard disk of the existing vm old_small.vdi is full and we want to resize it.


Create a new vm with the hard disk size you want. Call it new_big (the output is called new_big.vdi).




Then execute the following cmd:

$ VBoxManage clonehd --existing old_small.vdi new_big.vdi

That's it ;)
