AMD-V is not enabled in VirtualBox on AMD APU

  • 772

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

    First enable AMD-V in the BIOS. It depends on your BIOS, but it will look something like this (probably):

    In VirtualBox click -> Settings -> System -> Acceleration and enable the checkboxes as shown below.

  2. I had run into the very same problem and after spending like 2hrs I finally solved this. I am on a 32bit sys and my Bios does not have this Vizualization Technology option.

    The problem happened to be VirtualBox related, I did this:

    VirtualBox > System > Processor > change the number of processors from 2 to 1

    Worked for me.

  3. I have an ASUS TUF B450 mobo and it's under Advanced -> CPU -> SMV

    I also had to disable SecureBoot.
