VT-x error while running Kali Linux ovf on Virtual Box in 32-bit Windows 10?


I have successfully run Ubuntu on my computer with an older version of VBox in Windows 7.

I updated VBox, and downloaded and imported a Kali Linux 2017 i686 .ovf file. But then I got an error after which I installed the extension pack. Now I'm getting a different VT-x error.

If it helps, the Acceleration reads : PAE/NX, KVM paravirtualization. The acceleration tab in settings is disabled.

Failed to open a session for the virtual machine Kali-Linux-2017.1-vbox-i686.

VT-x is not available (VERR_VMX_NO_VMX).

Result Code: E_FAIL (0x80004005) Component: ConsoleWrap Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

I would follow: https://stackoverflow.com/questions/5482223/vt-x-is-not-available-when-i-start-my-virtual-machine

That error is more pointing to that your computers bios doesn't have virtualization enabled. That option isn't available on all CPU's.

Take a look into bios and verify that virtualization is enabled, if you can't find the option, verify that your CPU has the ability.

Most follow a VT- enable/disabled option, generally under CPU settings in bios.

Fix: vt-x is not available (verr_vmx_no_vmx) - Appuals.com

There are three most common reasons for this error:

  1. Your CPU doesn’t support VT-x or AMD-V virtualization

  2. VT-x or AMD-V is not enabled in BIOS (UEFI)

  3. You have Hyper-V virtualization enabled in Windows

Solution 1: Enable VT-x in BIOS

Restart your computer Load into BIOS (press Del, F2, Esc key. Depends on motherboard) Find Virtualization setting and enabled it. It might look different in you system, but here are some examples:

Solution 2

Open Control Panel Go to Program section -> Turn Windows features on or off Disable Hyper-V
