[How to Enable] VT-x is Disabled in the BIOS, (for All CPU Modes) Intel & AMD-V

For some reasons, if you find that vt-x is disabled in the BIOS, this guide will show you how to enable it on Intel and AMD based computers. The hardware virtualization technology extensions should be enabled in motherboard BIOS to run recent Operating Systems and some of the virtualization applications. Specifically, Windows 10, and 8.1 require VT-x/AMD-V enabled processors to accelerate the usage of desktop virtualization software like VMware, VirtualBox, and Hyper-V.

Even to install the latest Windows Operating Systems as the virtual machine, VT should be enabled on the host computer. Your PC processor and motherboard should support this feature, if they don’t, you can’t do anything to get this feature because it’s a built-in hardware feature. This simple guide explains how to enable Intel Virtualization Technology (vt or vt-x) for Intel processors and AMD-V for AMD processors.

BIOS VT

Modifying BIOS settings is tricky and it is different for each type of motherboards and BIOS. But you must enable it if it’s really required to install and run specific OS or applications. I highly recommend checking the manual or online guide of your motherboard vendor.

All the latest processors and motherboards support virtualization technology (vt-x/AMD-v). If you have an old PC, double-check the processor model for this feature. Before play around in BIOS, use the appropriate tools to detect the current VT-X status from OS level. If it’s already enabled (detected by these tools), then no changes required in BIOS.

VT-x is disabled in the BIOS, Where to Find Intel Virtualization Technology (VT-X) in BIOS?

It can be found under ‘Advanced Chipset settings’ in AWARD BIOS. Normally these vt-x/AMD-v extension settings will be available in advanced settings on most of the motherboards.

After you have changed the settings to disable or enable, it’s recommended to shut down the computer for a minimum of 10 seconds and restart it (Cold Restart) to take effect. Latest motherboards automatically detect these type of changes and do the cold restart. Whenever I change VT setting in my motherboard, it delays the restart automatically.

How to Confirm Virtualization Technology (vt-x/AMD-v) is Enabled or Disabled?

1) If your processor is made by Intel, use this free utility to see the result which operating system is sensing.

Download Intel virtualization technology detection tool here.

intel util

Once the utility is installed on Windows 10 or Windows 7/8.1 computer, you can use and identify the status as shown below. You can use this tool to enable VT-x on Windows 10 BIOS.

2) To check the status of AMD-V, AMD users can download AMD-V detection utility here.

3) There is a tool available from Microsoft which will work on both Intel and AMD processor Windows OS computers.

Download Microsoft Hardware-Assisted Virtualization Detection Tool from the official site here.

This tool doesn’t work on Windows 8, obviously, if you are using Windows 8, then vt-x/AMD-v is already enabled on the same PC, that’s why you were able to install Windows 8 or Windows 10 on it.

Installation is not required here, execute the EXE file and the following result will appear.

One of these above tools will help you to identify vt-x/AMD-v support on your laptop or desktop computer.

How to Fix vt-x is disabled in the BIOS for All CPU modes (verr_vmx_msr_all_vmx_disabled) – VirtualBox

You may get vt-x is disabled in the bios for all cpu modes (verr_vmx_msr_all_vmx_disabled) error when you switch on a VirtualBox virtual machine on Windows or Linux host machines. One of the main reason for this error is disabled vt-x on your host computer.

Here are the few solutions

a) Make sure that your computer motherboard and processor support hardware virtualization (VT-x) technology which we discussed here. Also, it should be enabled as described in this guide.

b) PAE and NX are not enabled in the BIOS. These features are like VT-x. These additional processor features should be enabled.

c) If you have installed Microsoft Hyper-V virtualization software, it may prevent the VirtualBox to read the hardware virtualization technology of the processor. You may need to uninstall Hyper-V to make Oracle VirtualBox work properly on Windows computer.

d) If all the above are correct, but still getting the same error message, you need to increase the RAM of the virtual machine. Also, check any 3rd party software such as antivirus which may interfere with the VT-x of the computer. So, the VirtualBox is not detecting it properly. I’m sure one of the above solutions will work.

With this article, if VT-x is disabled in the BIOS, you should know where to locate the place to enable hardware VT-x. If you use Hyper-v hypervisor on your desktop computer, make sure that Intel VT-x or AMD-V is enabled.  If you do not see this option in your motherboard, you must check the motherboard manual and specifications to identify whether the motherboard supports virtualization technology. Some of the old motherboards on desktop or laptop do not offer this feature.

    I know AMD-V that it supports sure. How do i enable under Ubuntu?

    Thanks

    • @SnakeMedia,
      I don’t know much about ubuntu. But I’m sure your OS is detecting Virtualization ( AMD-V) since you are running this command in OS layer.

      You cant enable VT in ubuntu or Windows OS, it should be enabled in BIOS only.

      • In fedora, it is found at BIOS settings ,security->system security
        Dint tried in ubuntu but you Can check the same in ubuntu.

    • Hey,
      It Does not Matter What Operating system are you using, But matters Which BIOS and processor are you using. If you have AMD-V Displayed in linux Terminal Then it is already enabled.

    • @lalal,
      It must be mostly under ‘Advanced Chipset features’ in BIOS. Also check the full details about your processor from vendor’s site.
      If you can’t find VT, nothing can be done except changing motherboard and processor. ;(

  3. I’ve been trying to use Virtualization on my Lenovo Ideapad z565 laptop. The laptop is running the OEM installed Windows 7 home premium 64. It is an AMD dual core processor. When I query the motherboard vendor, it just gives a generic name (“GUAM LENOVO”). I’ve attempted to launch a few VMWare images within VMWare workstation running on my laptop. The VMWare images always seem to hang when trying to launch them. I’ve read on various forums that this is most likely due to Virtualization Technology (VT) “Not” being enabled in the BIOS. This is supposed to be set in the “Advanced ” section of the BIOS. The problem is that when I check my BIOS (F2), the Virtualization Technology (VT) option is not listed in my BIOS. I have a very limited set of BIOS options. I’ve read that manufacturers of these machines will sometimes “Block” the user from accessing the advanced BIOS options (for reasons unknown to me). Also, There is a utility distributed by Microsoft called the “Hardware-Assisted Virtualization Detection Tool” that you can download and run on your computer to check if Hardware-assisted Virtualization (VT) is enabled on your computer. I have run this, and it says that VT “is” enabled on my machine. However, I’ve seen, from other users, that this tool is known to report false positives…meaning it reports that VT is enabled, even though it is not. I’ve also read that for these Lenovo laptops, that Hardware Virtualization is “disabled’ by default. So, I think that is my problem. Hardware Virtualization is turned off in my BIOS, and I have no way to access it in order to ‘enable’ or turn it on. Does anyone out there have any experience with this problem, and how did you work around it? Is there a utility that will allow me to enable Hardware Virtualization in my BIOS? If so, can you provide me with the detailed steps to do this? I would really appreciate it. Thank you.

  13. Hi,

    I have AMD Athlon x2 5200, checked mentioned tools = ok BIOS virtualization = OK.
    When i want to run mac os i see
    “Mac OS X is not supported with software virtualization. To run Mac OS X you need a host on which VMware Workstation supports hardware virtualization.”

    Any idea ?

    • you can still run VM on your pentium 4, the catch is that you can only run 32 bit OS not 64 bit.. If you have less then 2GB of RAM it will slow your performance when running your VM.

  17. Siraj if you are really running a P4 you should trash that and go buy a REAL MAC.
    Stop trying to run OS X in a VM on a ten year old PC!

  18. so according to the comments, after updating the BIOS i still cant see the Virtualization, there’s nothing else to do right?
    i installed the update for dm061 but nothing.
