I have been trying to enable Virtualization of my cpu to run a 64 bit guest OS. Anybody having an idea ?
EDIT : My cpu supports virtualization. http://ark.intel.com/Product.aspx?id=35562 the problem is I couldn't enable it. Setup screen doesn't have any option to make it! I'm currently using Windows 7 Ultimate x64

Short answer: You can't. Or at least you shouldn't.
Long answer:
Usually you enable things like VT in the BIOS. To get into the BIOS, reboot the machine and it will tell you which key (mostly F1/F2/ESC/DEL or similar) you have to press in order to get there. Unfortunately your machine's BIOS won't help because there is no option to activate VT. (Yes, Acer intentionally crippled your machine. So do many other manufacturers.)
Now the "You shouldn't"-part: You could try to install a modified version of the BIOS but that might introduce new problems like instabilities or even brick your notebook. More info:
