Ubuntu – AMD-V is not enabled in VirtualBox on AMD APU

I am running on a dual core AMD E450 CPU. When I tried to run a 64-bit OS that requires hardware virtualization using VirtualBox, it showed me an error message that "AMD-V is not enabled".

My AMD processor is supposed provide AMD-V support, but I can find no option for enabling AMD-V in BIOS.

How can I solve this problem? How can I enable AMD-V for my CPU?

Thanks in advance
