title: How to enable VT-x/AMD-v in Aspire V5-122P bios?
body: <p>I have been trying to download and run Back track Linux 5 r3 on my windows 8.1 (AMD Quad-Core processor, 64bit Intel.) using Virtual Box. It kept giving me the error "This Kernel requires an x86-64 bit cpu but only detected an i686 cpu so I downgraded to 4.2 Virtual Box. That solved the problem but now I keep getting an error when I run Virtual Box linux with Ubuntu 64 bit "VT-x/AMD-v hardware acceleration is enabled but not operational. Your 64-bit guest will fail to detect a 64-bit cpu and will fail to boot. Please ensure that you have enabled VT-x/AMD-v properly in the bios of your host computer." I have searched and digged through the internet and found nothing useful to my predicament. How can I enable VT-x/AMD-v in my windows 8.1 bios so I can run Back Track Linux properly? Ive looked through my bios and found nothing relevant to Virtualization or VT-x/AMD-v so I came here. Thanks :D</p>
