Increase dynamic VDI disk size

linuxvirtual machinevirtualboxwindows 7

I'm running Linux (OpenSuse) host (Oracle VirtualBox) with Win 7 guest. I configured the VM with a VDI format disk that grows dynamically as required. Windows currently has 3.5 Gb free but I need to increase that to 9Gb in order to install SP1 and I'm not sure how to go about it.

I found this http://derekmolloy.ie/resize-a-virtualbox-disk/ which is Windows Host/Linux Guest so it gives me a good heads up but anything more specifically applicable to my configuration would be very helpful.

turns out this is very easy:

  • in linux host terminal VBoxManager modifyhd --resize {Megabytes} {fileName}
  • In Windows Guest: open Disk Management Applet and use resize partition function
