VirtualBox vt-x not enabled even though it is

Heya,
So when I try to launch my amd64 VM from VirtualBox I am getting "vt-x Not enabled" Error even though Intel Virtualization Technology is enabled in my BIOS (laptop Lenovo ideapad Z710). I read somewhere that amd64 does not utilize vt hence I am thinking about using a 64bit Version instead. Could this do the Trick? Any other ideas?

  • What OS are you running on that laptop? Is it 32bit or 64bit?

    Anyway try updating the BIOS if there is a newer one.

  • Unsure why VT-X is needed on a laptop?

    Had that in the past, on a lenovo you need to do this:

    Disable it in the bios, save the settings, power off the laptop fully i.e. take the battery out.

    Boot it up, enable it, save the settings, power off the laptop fully again.

    Boot it up and it should now be enabled.

    so simple but I wasted 2 days working that out.

  • You might find something like hyper-V or another virtualization system is using VT-X, disabling it for virtualbox - I've had this before.

    Because people nowadays use virtual machines.

    Development, compatibility of old apps, having an Unix os on Win/OSx, or vicevers, sandboxing, are some of the reasons.
