On Pro versions of Windows you can do this using gpedit.msc (set Local Computer Policy > Computer Configuration > Administrative Templates > System > Device Guard > Turn on Virtualization Based Security to Disabled.

On some Windows hosts with an EFI BIOS, DeviceGuard or CredentialGuard may be active by default, and interferes with OS level virtualization apps in the same way that Hyper-v does.

So make sure to fully power down and reboot the host after changing the Hyper-v setting. Note that this changed a boot option, hence it will only take effect on next boot. If you want to be absolutely sure that Hyper-v is gone then open an administrator command console and type " bcdedit /set hypervisorlaunchtype off". The box should be empty, not checked or shaded. To check the status of Hyper-v in Windows 10, | Run | OptionalFeatures.exe, and look for the "Hyper-V" option.

Hyper-v competes for resources and needs to be disabled.

This has become more important since VirtualBox 4.3.x, because choosing the correct template also allows other modern processor features to be visible to the guest - it's not just about 64bit capability any more. choose "Ubuntu (64 bit)" and not "Ubuntu" or "Ubuntu (32bit)", otherwise a 64-bit guest OS may refuse to install.

When creating a VM, make sure you choose the 64-bit version of the guest OS template in | General | Basic | Version, e.g.

Note: see the fourth post below for other Win10 functions that have this effect. This has become a particular issue with 64bit Windows desktop and server hosts - especially Win2k12, Win10 and later, as these may enable Microsoft's Hyper-v VM platform by default: this grabs ownership of VT-x and won't play nice with VirtualBox. The usual culprits are system level debuggers, other VM platforms, and some resident anti-virus applications.

If (1) and (2) are already taken care of, then make sure that no other host apps are already using VT-x/AMD-v.

If you can find the latter option but can't find the former, and it's a recent PC (post 2016) then it's likely that VT-x/AMD-v is enabled by default in your BIOS, so go to step 3! Remember to cycle power on your host PC after making and saving the BIOS changes - in this case a full restart from power off is required, just rebooting or resuming from a hibernated state may not do the job. If you see "Virtual Directed I/O" (VT-d/AMD-Vi) then that is a different thing. The option may be called something like "Enable Virtualization Technology", "Enable SVM Mode" (AMD CPUs), "Enable Vanderpool Technology" (Intel), or perhaps "Secure Virtual Mode". Once you get there you need to look for something buried in a menu, perhaps in the security category. This is probably not something we here at the VirtualBox forums can help you with.

You need to check with your PC manual or support forum to find out how to boot into the BIOS screen.

You usually need to enable VT-x/AMD-v in the host PC BIOS.The CPU must be 64bit and support either Intel or AMD virtualization technologies: VT-x or AMD-v. Note your exact CPU model or part number, then go online and check its capabilities.To ensure that you can still run VMs in those categories, run through the following checklist :. The developers clearly feel that supporting older machines that don't have this hardware feature is no longer justified commercially. Starting with VirtualBox 6.1.0 the latter is now true for all other hosts. OS X hosts require VT-x/AMD-v for every VM. This includes all 64bit VMs, and all VMs which use >1 CPU core. VirtualBox requires hardware support for virtualization (Intel VT-x or AMD-v) in order to run certain categories of VM. The original text remains below, the "bittedness" stuff is now less relevant, but the underlying problem and solutions have not changed. However VirtualBox 6.1.x now requires VT-x/AMD-v to be available (or Windows NEM, but we'll leave that for now) for all VMs, whether 32bit, 64bit, single or multiple vCPU and so on. If the topic had been called "VT-x not available error" then newbies may not have understood the relevance. This topic has the name it has because that was how most users encountered the problem of VT-x/AMD-v hardware accelerated virtualization not being available.
