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

Virtual makers are wonderful things. V virtualization apps, you can run an entire virtual computer system in a window on your existing system. Within that digital machine, you can run various operating systems, check apps in a sandbox environment, and experiment with features without worry. In order to work, those virtual device apps need hardware acceleration features constructed into modern-day CPUs. Because that Intel CPUs, this method Intel VT-x hardware acceleration. For AMD CPUs, it method AMD-V hardware acceleration.

At part point, you might encounter error messages in her VM apps like the following:

VT-x/AMD-V hardware acceleration is not obtainable on her systemThis hold supports Intel VT-x, yet Intel VT-x is disabledThe processor top top this computer is not compatible with Hyper-V

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

These errors deserve to pop up because that a pair of different reasons. The very first is the the hardware acceleration function may be disabled. On systems v an Intel CPU, the Intel VT-x feature can it is in disabled via a BIOS or UEFI firmware setting. In fact, it’s often disabled through default on brand-new computers. On solution with one AMD CPU, this won’t it is in a problem. The AMD-V attribute is always enabled, therefore there’s no BIOS or UEFI setup to change.

The other reason this errors can pop increase is if you’re make the efforts to use a virtualization app like VMWare or VirtualBox when you already have Microsoft’s Hyper-V installed. Hyper-V takes end those hardware acceleration features and also other virtualization apps won’t be able to access them.

So, let’s take it a look at how to deal with 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 more often happens v Intel VT-x hardware, yet can also happen v AMD-V top top occasion. If this is the case, you’ll watch an error blog post in her virtualization application to the effect that Intel VT-x (or AMD-V) is unavailable, even though it is allowed on her computer.

To fix this problem, you just need to uninstall Hyper-V. Hyper-V is an optional home windows feature, so uninstalling the is a small different 보다 uninstalling a continuous app. Head to control Panel > Uninstall a Program. In the “Programs and also Features” window, click “Turn Windows attributes on or off.”

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

When windows is excellent uninstalling Hyper-V, you’ll need to restart your PC and also then you can try utilizing VirtualBox or VMware again.

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

If you have an Intel CPU and also uninstalling Hyper-V didn’t resolve your problem—or your virtualization application reported that Intel VT-x was disabled—you’ll require to accessibility your computer’s BIOS or UEFI settings. Pcs made prior to the release of home windows 8 probably use BIOS. Pcs made after home windows 8 came out may use UEFI instead, and also the likelihood of utilizing UEFI grows the more contemporary the PC.

On a BIOS-based system, you’ll accessibility BIOS settings by restarting her PC and also pressing the appropriate key right as soon as it first boots. The vital you press depends on her PC’s manufacturer, but it’s frequently the “Delete” or “F2” key. You likewise will most most likely see a message throughout startup that says something favor “Press Key to accessibility setup.” If girlfriend can’t number out the right an essential to gain into her BIOS settings, just perform a net search because that something choose “computer model_number accessibility BIOS.”

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

Whether her PC offers BIOS or UEFI, when you’re in the setups menu, you can start looking roughly for an choice labeled something prefer “Intel VT-x,” “Intel Virtualization Technology,” “Virtualization Extensions,” “Vanderpool,” or miscellaneous similar.


\"*\"

Often, you’ll discover 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 also Exit” or the equivalent attribute to save your settings changes and reboot your PC.


After the pc restarts, you can try making use of VirtualBox or VMware again.

What to carry out If you Don’t see the Intel VT-x option in BIOS or UEFI

Unfortunately, some laptop manufacturers and also motherboard manufacturers don’t include an choice in your BIOS or UEFI settings for enabling Intel VT-x. If friend don’t watch the option, try performing a web search because that the model number 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 upgrade that has this option. Updating her BIOS or UEFI firmware can help—if you’re lucky.

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