VirtualBox is slow !

So my host OS is Windows 8 and I wanted to separate my everyday stuff from my projects (coding) stuff.
I created a virtual machine, guest OS is Linux Mint.
My PC is: intel i3570K, 8GB DDR3, 64SSD + 128SSD, Asus Z77. Not a bad one!


So when I was in Mint, it was kind of slow.

 In settings > System > Processor, I had only 1 processor and when I selected 2 processors, I could see a warning message saying something like "this is not the most efficient setup". I ignore this message and in settings > System > Accelation, I checked "Enable VT-x/AMD-v".
When I start my virtual machine, I add an error message and the machine didn't start at all.


After searching on the Web, I found out that I had to go to the bios and activate a feature.
I don't remember exactly the name of the feature (and I guess it depends of the motherboard), but it was in the CPU section, and the feature was like "activate virtualization something".

After activating it, I could select 2 CPU and now my virtual machine is not slow anymore!

And that's it!
