How to resize virtualbox vdi disk

How to resize virtualbox vdi disk

• Use case : you have a virtual box vm (Oracle Vbox version 6.x+) with a linux system - say debian - but the vdi disk you attached is to small, and your sda partition are running very low in space.

• Solution : increase de size of the vdi disk and resize your partitions with gparted.

• How to (very short) :

  • Backup your vm (“Export” as ova image is a good idea)

  • Virtual box app menu : File (Fichier) -> Media Manager (Gestionnaire de media) -> Tab “Attibutes” : chose size and click on apply. Caution : you cannot resize vdi disk if the VM has snapshots (clear them all before).

  • Mount a Gparted live cd at startup and resize your system partitions.
