I noticed on dynamically allocated virtual hard drives, installing any OS takes longer than if I were using fixed size virtual hard drive. This may no longer be true when using SSDs, but it would be a few more years before SSDs are as affordable and high capacity as today's HDDs. So if I know that an OS install would take up 3.5G, I would create a 20GB dynamically allocated hard drive but set about 5GB of pre initialized space." enhancement closed GUI VirtualBox 4.2.6 wontfix all all
