While there is no way to actually switch a VDI between fixed-size and dynamic, you can clone the existing VDI into a new one with different settings with VBoxManage.

VBoxManage clonehd [old-VDI] [new-VDI] --variant Standard
VBoxManage clonehd [old-VDI] [new-VDI] --variant Fixed

If you want to expand the capacity of a VDI, you can do so with

VBoxManage modifyhd [VDI] --resize [megabytes] 

Ex. VBoxManage modifyhd Ubuntu12.vdi --resize 30000 (30GB)

On a linux guest you need to resize the partion to take advantage of the resized disk.

Examples:

VBoxManage clonehd Ubuntu12.vdi Ubuntu12Dynamic.vdi --variant Standard

I didn't know where to post so I posted my problem here. I want to create a virtual machine with fix sized disk on virtualbox. How can I do this?

Fantastic!
I Also found that you can do it with "Virtual Media Manager" from "File" menu, using copy button and following the steps
