Increasing disk space on VirtualBox

Is there an easy way to increase virtual hard disk space on VirtualBox?

Solution 1:

There is not an easy way to do this.

There is a complicated one, though:

Has a good screenshot-by-screenshot guide. Essentially you're copying your install onto a new virtual-disk file.

Update: As of VirtualBox 4 they added support for expansion.

VBoxManage modifyhd filename.vdi --resize 46080

That will resize a virtual disk image to 45GB.

Solution 2:

The Trivial Proof blog has a nice tutorial of the process for VirtualBox versions before and after 4.0. It includes the steps for adjusting the partition on the expanded disk.
