Virtual machines (Vm's) are useful in many ways. With virtualization software's such as VMware and Virtualbox, it's possible to run a virtual computer within your current operating system. This is known as running an operating system within a virtual environment. Within that virtual environment, you can run pretty much run any operating system, test apps within those operating systems, and experiment with features without worrying about needing specific hardware or even software requirements in some cases. In order to work without issues, those virtual machine softwares need hardware acceleration features built into modern CPUs. For Intel CPUs, it's referred to as Intel VT-x hardware acceleration. For AMD CPUs, it's referred to as AMD-V hardware acceleration.
What To Check For
Turn Intel VT-x On in Your BIOS or UEFI Firmware
On the off chance that you have an Intel CPU and uninstalling Hyper-V didn't tackle your concern—or your virtualization application announced that Intel VT-x was disabled—you'll have to get to your PC's BIOS or UEFI settings. PCs made before the arrival of Windows 8 likely use BIOS. PCs made after Windows 8 came out may utilize UEFI, and the more present day the PC, the almost certainty your PC utilizes UEFI.
On a BIOS-based framework, you'll access BIOS settings by restarting your PC and spamming the proper key right when it first boots. The key you press relies upon your PC's maker, yet it's regularly the "Delete" "Escape" or the "F2" key. You additionally will in all probability have a message during startup that says something like "Press {Key} to access bios." If you can't make sense of the correct key to get into your BIOS settings, simply play out a web search for something like "(computer make) (computer model_number) access BIOS."
On a UEFI-based PC, you can't really simply press a key while the PC is booting. instead, you'll have to hold down shift while you click restart. At that point To get to the UEFI Firmware Settings, which are the nearest thing accessible to the regular BIOS arrangement screen, click the Troubleshoot tile, select Advanced Options, and select UEFI Firmware Settings. Hold down the Shift key as you click Restart in Windows to reboot directly to that menu.
Regardless of whether your PC utilizes BIOS or UEFI, when you're in the settings menu, you can start searching for a setting in one of the menus titled something like "Intel VT-x," "Intel Virtualization Technology," "Virtualization Extensions," "Vanderpool," or something else comparable.
Frequently, you'll discover the virtualization setting under a "Processor" submenu. That submenu might be found some place under a "Chipset," "Northbridge," "Progressed Chipset Control," or "Progressed CPU Configuration" menu.
Empower the option and then select (Save and Exit) or the identical element to save your settings changes and restart your PC.
After the PC restarts, you can try utilizing VirtualBox or VMware once more.
What to Do If You Don’t See the Intel VT-x Option in BIOS or UEFI
Shockingly, some PC makers and motherboard producers don't include a choice in their BIOS or UEFI settings for empowering Intel VT-x. If you don't see the that setting, take a stab at playing out a web look for the model number of your PC—or your motherboard and "turn on Intel VT-x".
Now and again, motherboard/computer makers may have made a later delivery of a BIOS or UEFI firmware update that incorporates this option. Updating your BIOS or UEFI firmware might help. in case you're not fortunate.
and on the off chance that you don't have a more established CPU, it may not uphold the Intel VT-x or AMD-V features at all.
One Other Thing To Try...
Try Uninstalling Hyper-V
In any case that you have Hyper-V installed, it tends to hog resources pertaining to virtual acceleration. This almost always happens more with Intel VT-x hardware, but can also occur on AMD-V on occasion. by any chance Hyper-V has hogged all the resources, you’ll see an error messages in your virtualization app to the effect that Intel VT-x (or AMD-V) is unavailable, even though it is enabled on your computer.
To get rid of this error message and use your VM, all you need to do is uninstall Hyper-V. Hyper-V is an optional Windows feature, so uninstalling it is a tad bit different than uninstalling an app the usual way. Here's how you uninstall Hyper-V:
Control Panel > Uninstall a Program. In the “Programs and Features” window, click “Turn Windows features on or off.”
In the “Windows Features” window, uncheck the “Hyper-V” checkbox and then click “OK.”
When Windows is done uninstalling Hyper-V, you’ll need to restart your PC and then you can try using VirtualBox or VMware again.
Last Thoughts
Well, let's face it,virtual machines are great. So I hope you continue to use them! Ialso hope you learned how to check/get your VM working correctly if you get this error message. Please don't forget to subscribe to my YouTube Channel if you haven't already!
