VirtualBox Graphic User Interface Version 4.1.2_Ubuntu r38459 (installed with Ubuntu Software Center)

Host OS: Ubuntu 11.10
Guest OS: Windows XP sp 3 (with guest additions installed)

I have search on Google about this topic but not find any help yet. I read some topic that say VirtualBox v 4 now support dynamic RAM allocation but I do not know how to enable this feature.

Can you show me how to enable it?

Can you describe how exactly? And does this make the guest OS have more memory for it's running applications? –  trusktr Jun 26 '13 at 17:35
