Modern CPUs encompass hardware virtualization features that help accelerate online machines developed in VirtualBox, VMware, Hyper-V, and also other apps. However those functions aren’t always allowed by default.

Virtual machines are exorbitant things. Through virtualization apps, you can run an entire virtual computer in a home window on your existing system. In ~ that digital machine, you have the right to run different operating systems, test apps in a sandbox environment, and also experiment with functions without worry. In order come work, those virtual an equipment apps need hardware acceleration features developed into modern CPUs. For Intel CPUs, this means Intel VT-x hardware acceleration. Because that AMD CPUs, it means AMD-V hardware acceleration.

At some point, you might encounter error messages in your VM apps choose the following:

VT-x/AMD-V hardware acceleration is not obtainable on your systemThis host supports Intel VT-x, however Intel VT-x is disabledThe processor on this computer system is no compatible through Hyper-V

RELATED: What Is UEFI, and also How Is It various from BIOS?

These errors have the right to pop up for a couple of different reasons. The very first is the the hardware acceleration attribute may it is in disabled. On systems through an Intel CPU, the Intel VT-x attribute can be disabled via a BIOS or UEFI firmware setting. In fact, it’s regularly disabled through default on brand-new computers. On systems with an AMD CPU, this won’t be a problem. The AMD-V feature is constantly enabled, for this reason there’s no BIOS or UEFI setting to change.

The various other reason these errors deserve to pop up is if you’re do the efforts to use a virtualization app like VMWare or VirtualBox when you currently have Microsoft’s Hyper-V installed. Hyper-V takes end those hardware acceleration features and other virtualization apps won’t be able to accessibility them.

So, let’s take it a look at exactly how to solve these issues.


Try Uninstalling Hyper-V

If you have actually Hyper-V installed, it gets greedy and won’t let various other virtualization apps accessibility hardware acceleration features. This much more often happens with Intel VT-x hardware, but can also happen with AMD-V on occasion. If this is the case, you’ll view an error article in your virtualization app to the impact that Intel VT-x (or AMD-V) is unavailable, even though the is allowed on her computer.

To deal with this problem, you just need come uninstall Hyper-V. Hyper-V is an optional windows feature, for this reason uninstalling that is a small different than uninstalling a continual app. Head to regulate Panel > Uninstall a Program. In the “Programs and Features” window, click “Turn Windows functions on or off.”

*

In the “Windows Features” window, clear the “Hyper-V” checkbox and then click “OK.”

When windows is done uninstalling Hyper-V, you’ll need to restart your PC and also then girlfriend can try making use of VirtualBox or VMware again.

Turn Intel VT-x on in your BIOS or UEFI Firmware

If you have an Intel CPU and uninstalling Hyper-V didn’t solve your problem—or her virtualization application reported that Intel VT-x was disabled—you’ll require to access your computer’s BIOS or UEFI settings. Pcs made before the relax of home windows 8 more than likely use BIOS. Pcs made after home windows 8 come out may use UEFI instead, and also the likelihood of making use of UEFI grows the more modern-day the PC.

On a BIOS-based system, you’ll access BIOS settings by restarting her PC and also pressing the appropriate an essential right when it first boots. The key you push depends on your PC’s manufacturer, yet it’s regularly the “Delete” or “F2” key. You additionally will most most likely see a message during startup that states something prefer “Press Key to access setup.” If you can’t figure out the right vital to obtain into your BIOS settings, just perform a net search because that something choose “computer model_number accessibility BIOS.”

On a UEFI-based computer, you can’t necessarily simply press a key while the computer is booting. Instead, you’ll have to follow this instructions to accessibility the UEFI firmware settings from the Windows advanced startup options. Hold down the Shift an essential as girlfriend click Restart in home windows to reboot straight to the menu.

Whether her PC supplies BIOS or UEFI, once you’re in the settings menu, girlfriend can begin looking about for an choice labeled something favor “Intel VT-x,” “Intel Virtualization Technology,” “Virtualization Extensions,” “Vanderpool,” or miscellaneous similar.


*

Often, you’ll uncover the option under a “Processor” submenu. The submenu may be located somewhere under a “Chipset,” “Northbridge,” “Advanced Chipset Control,” or “Advanced CPU Configuration” menu.

Enable the option and then select “Save and Exit” or the equivalent attribute to conserve your settings changes and reboot your PC.


After the pc restarts, you can try using VirtualBox or VMware again.

What to perform If friend Don’t check out the Intel VT-x option in BIOS or UEFI

Unfortunately, some laptop manufacturers and motherboard manufacturers don’t include an option in your BIOS or UEFI settings for allowing Intel VT-x. If you don’t check out the option, try performing a net search for the model variety of your laptop—or her motherboard, if it’s a desktop computer PC—and “enable Intel VT-x”.

In part cases, manufacturers may later on release a BIOS or UEFI firmware update that consists of this option. Updating her BIOS or UEFI firmware could help—if you’re lucky.

And, remember—if you have actually an larger CPU, it might not support the Intel VT-x or AMD-V hardware virtualization functions at all.
