Virtualbox Showing Only 32 Bit

Posted on by

I am running VirtualBox v5.2.32 on an Ubuntu 18.04 host. I have created a Windows 10 (64-bit) guest. I installed VirtualBox v6.0.10 in the Windows 10 guest (Windows 10 Pro – v1903 – 64-bit). I am trying to create an Ubuntu (64-bit) guest inside the Windows 10 guest. I only see 32-bit options inside the Windows guest. After several attempts to resolve this, I am still only seeing 32-bit options.

The purpose for creating a VM inside a VM is to be able to ensure that VirtualBox is working so that I can test Vagrant configuration inside a Windows 10 environment. Our Vagrant config is using 64-bit base images, so I need to be able set up 64-bit guests inside this Windows 10 guest. Kubota svl90 service manual.

…on the Ubuntu Host

I have checked Enable VT-x/AMD-V on the System > Acceleration tab in the Ubuntu host's VirtualBox config for the Windows 10 guest machine.

…on the Windows Guest

  2. This tutorial will show you step by step what to do when VirtualBox is only showing 32-bit and no 64-bit versions of operating systems as options while creating a new virtual machine. Note: This may be obvious for most of you, but your host operating system should be 64-bit to run 64-bit guest operating systems in VirtualBox.

In the Windows guest machine, I can see that the host's physical CPU details are passed through in Settings > System > About and it shows as a '64-bit operating system, x64-based processor'.

This is a vanilla Windows 10 Pro installation, no additional software (i.e., no addon virus protection software).

When I'm trying to create a new Virtual Machine in VirtualBox running on a MacBook Air with a M1 chip I can only see 32-bit Versions of Windows, Linux, etc. I also have been trying to access Open Firmware but it seems the new chip does not have anything like this.

I inspected Windows Features to ensure that the following are not checked:

Windows
  • Guarded Host
  • Hyper V
  • Virtual Machine Platform
  • windows Hypervisor Platform
  • Windows Subsystem for Linux

…because my googleing seems to indicate that some or all of these might be an issue.

Based on a VirtualBox forum (I have a 64bit host, but can't install 64bit guests), using gpedit.msc, I set Local Computer Policy > Computer Configuration > Administrative Templates > System > Device Guard > Turn on Virtualization Based Security to Disabled. I also check that Windows Security > Device Security > Core Isolation Details is set to Off.

I have 'repaired' the VirtualBox installation. I have uninstalled VirtualBox, rebooted, reinstalled, and then rebooted again.

I looked at these related, previously asked questions and followed their suggestions as indicated in the steps above. Everything I am finding seems to be related to a Windows 64-bit host running directly on the host machine, not dealing with a Windows host which is itself a guest VM.

When trying to create a Virtualbox VM recently I was only presented with the option of creating a 32-bit client. After a bit of research it turns out this can be caused by incorrect settings in the BIOS or by a competing Virtual Machine software cohabiting the system.

CPU

First of all your CPU must support the virtualization extensions. We can check this on a Bash console if you have installed the integrated feature.

If it returns a positive number, 1 or higher your CPU does support the virtualization extensions. You must still ensure it's enabled in the BIOS. If it returns 0 then your CPU does not support hardware virtualization.

BIOS

You must have hardware virutalization enabled in the BIOS to create and run 64-bit virtual machines.

The following BIOS features need to be enabled:

  • Intel Virtualization Technology [Enabled] (or AMD-v).

Hyper-V

If Hyper-V is enabled then Virtualbox will not be able to create 64-bit virtual machines. Download igi.

If Hyper-V was enabled this will require a reboot.
