How to enable virtualization in BIOS? This question was asked by a large number of personal computer users. Some people have probably heard of such technology, but don't understand what benefits it can provide, and what it is all about. These questions will be discussed in this article.
What is virtualization?
Before telling you how to enable virtualization support in BIOS, you need to explain what it is. In computer technology, this term refers to the modeling of hardware using software methods. Thanks to virtualization technology, you can create a number of virtual computers, that is, those that are simulated in software. In this case, only one sufficiently powerful computer of the physical type is used.
Main advantages
Why is virtualization good? Here are its main benefits:
- Increases the efficiency of hardware use.
- Reduced material costs.
- The distribution of resources is optimized.
- Work safety is getting better.
- More simplified administration.
- Increased reliability.
In order to create virtual systems, special software called a hypervisor is used. But due to some features of the old processors built on the Intel architecture, the hypervisor could not use their computing power as efficiently as possible in order to create virtual machines.
For this reason, leading companies developing processors for personal computers have created hardware virtualization technology. It is able to optimize the operation of processors in such a way as to greatly increase the efficiency of the software for this process. Intel's hardware virtualization technology is called Intel-VT, while AMD's is called AMD-V.
Principle of operation
It is based on the division of the processor into guest and monitor parts. For example, when switching from the host OS to the guest, the processor automatically switches to the guest state. At the same time, it shows the system such register values that it wants to see and which it needs for stable operation. Thus, the processor is a "deceiver", which saves the system from all sorts of tricks. The guest OS works directly with the processor, making the virtual machine run much faster than on a non-virtualized PC.
Technology support
Since hardware virtualization is integrated into the CPU, in order for the user to get the most out of its benefits, it is necessary that his computer also supports this technology at the processor level. In addition, it is also necessary that the technology be implemented by the operating system and BIOS. If the latter supports hardware virtualization, the user gets the opportunity to enable or disable it in the settings. It should be noted that there are chipsets for motherboards based on AMD processors, and in which there is no way to turn off support for this technology.
How to enable virtualization in BIOS?
To enable and disable this option in the BIOS, there is a special function, which is called Virtualization Technology. Typically, this option is found in sections related to the CPU or chipset.
So, how to enable virtualization in BIOS? Very simple. Typically, setting the value to Enabled enables the technology, and the value Disabled disables it. Keep in mind that activating the setting only affects the performance of virtual machines that run within the hypervisor. The performance of all operating system programs is not affected in any way.
Different manufacturers use their own settings, but it's still not difficult to enable virtualization in the BIOS (Asus, Lenovo and others have similar settings).
Conclusion
We figured out how to enable virtualization in BIOS. This technology is a very powerful tool that allows you to expand the capabilities of computers and make much more efficient use of the available hardware. Most modern personal computers have processors that have this solution built into them. This improves their performance if virtual machines are used. In addition, most PCs have the ability to configure support for hardware virtualization.
Some users are interested in how to enable virtualization without BIOS. This is impossible to do, since hardware manufacturers are introducing technology into hardware. And only the BIOS has direct access to it.
Virtualization technology can improve your computer's performance and make Nox App Player run smoother and faster.
1. Does your computer support Virtualization Technology (VT)?
To check if your computer can support VT, just download LeoMoon CPU-V. This will not only detect if your processor can support hardware virtualization, but it will also detect if Hardware Virtualization is enabled in the BIOS or not.
If the check result shows a green check mark under VT-x Supported, it means that your computer supports virtualization. If it's a red cross, then your computer doesn't support VT, but you can still install Nox if the installation requirements.
1.If the test result shows a green checkmark under VT-x enabled, then it means that VT is already enabled in your BIOS. If it's a red X, then follow these steps to turn it on.
2. Determine your BIOS type: Press Win + R to open the "Run" window, type "DXDiag" and click the "OK" button. After that, you will see the BIOS information as shown in the picture below.
3.Then search Google for exactly what needs to be done to enable VT for that specific BIOS. Usually, to enter the BIOS, you need to press a certain key several times when your computer boots up. The assigned key can be any function key or ESC key, depending on the brand of your computer. After entering BIOS mode, look for VT-x, Intel Virtual Technology or something similar that says "Virtual" and turn it on. After that, turn off your computer, then turn it back on. Now virtualization is enabled and the performance of Nox App Player is even better.
Attention!!!
- If you are running Windows 8 or Windows 10, there may be a conflict between VT and Microsoft Hyper-V technology. Please disable Hyper-V by doing the following: Go to Control Panel-> Programs and Features-> Turn Windows features on or off > Uncheck Hyper-V.
- 2. If VT is enabled in the BIOS, but the LeMoon check result still shows a red cross under VT-x Enabled, then there is a good chance that your antivirus is blocking this feature. Let's take Avast antivirus as an example! What needs to be done to solve this problem:
1) Open Avast Antivirus >> Settings >> Troubleshooting
2) Uncheck Enable virtualization with hardware, then restart your computer.

Today, an increasing number of modern computer systems are turning their attention to virtualization technologies. True, not everyone has a clear enough idea of what it is, why it is needed and how to solve the issues of its inclusion or practical use. Now it will be considered how to enable virtualization in the BIOS using the simplest method. We note right away that this technique is applicable to absolutely all existing systems, in particular, to the BIOS and the UEFI system that replaced it.
What is virtualization and why is it needed?
Before proceeding with the direct solution of the problem, how to enable virtualization in the BIOS, let's see what this technology is and why it is needed.
The technology itself is intended for use in any operating system of so-called virtual machines that can emulate real computers with all their hardware and software components. In other words, in the main system, you can create some with the selection of a processor, RAM, video and sound card, network adapter, hard drive, optical media, and God knows what else, including installing a guest (child) "OS", which will be nothing different from the real computer terminal.
Varieties of technologies
If anyone does not know, virtualization technologies were created by leading processor manufacturers - Intel and AMD corporations, which today cannot share the palm in this area. At the dawn of the era, the created hypervisor (software for managing virtual machines) from Intel did not meet all the requirements in terms of performance, which is why the development of support for virtual systems began, which were supposed to be "hardwired" in the processor chips themselves.
Intel called this technology Intel-VT-x, and AMD called it AMD-V. Thus, the support has optimized the performance of the CPU without affecting the main system.
It goes without saying that you should enable this option in the BIOS presets only if you plan to use a virtual machine on a physical machine, for example, to test programs or predict the behavior of a computer system with various hardware components after installing a particular operating system . Otherwise, such support may not be used. In addition, it is generally disabled by default and, as already mentioned, it has absolutely no effect on the performance of the main system.
Entering BIOS
As for BIOS or UEFI systems, any computer or laptop has them, regardless of the complexity of the installed equipment. The BIOS itself on the computer is a small chip on the motherboard, which is responsible for testing the hardware when the terminal is turned on. In it, despite the memory of only about 1 MB, the main settings and characteristics of the equipment are saved.
Depending on the BIOS version or manufacturer, there are several different methods for logging in. The most common is to use the Del key immediately after turning on the computer or laptop. However, there are other methods, such as the F2, F12 keys, etc.
How to enable virtualization in BIOS in the simplest way?
Now let's define some basic parameters and menus. We start from the fact that the entrance to the BIOS on the computer has already been made. There are several main sections here, but in this case we are interested in everything related to the processor chip.
Usually such options are contained in the advanced settings menu (Advanced) or in the security section (Security). They can also be called differently, but, as a rule, it is something like Processor or BIOS Chipset (although other names may occur).
So, now the question of how to enable virtualization in BIOS can be considered closely. In the above sections, there is a special line Virtualization Technology (in the case of Intel, the name of the corporation is added to the main name). When entering the corresponding menu, two available options will be shown: Enabled and Disabled. As is already clear, the first is the virtualization mode enabled, the second is a complete shutdown.
The same applies to the UEFI system, in which the inclusion of this option is performed in a completely similar way.
Now that the BIOS setting has been applied to the enabled mode parameter, all that remains is to save the changes (F10 or the Save & Exit Setup command), press the Y confirmation key corresponding to the English word Yes. The reboot of the system with the newly saved parameters starts automatically.
What should you know besides this?
As you can see, the procedure for enabling virtualization in the BIOS is quite simple. However, here you should take into account some subtleties associated with the possible disabling of this function. The fact is that when using virtual machines like WMware Virtual Machine, Virtual PC, VirtualBox, or even the “native” Microsoft module called Hyper-V, this option must be enabled without fail, even if support for Windows components is enabled directly in the system settings.
For the most part, this applies to newer modifications of Windows, starting with the "seven". In "Exp" or "Vista" this is not a prerequisite. Although if such "OSes" are installed on the latest "iron", the inclusion of support may also be required. However, it is unlikely that the user on such a machine will install a morally obsolete “OS” that will not allow “squeezing out” the maximum of what it is capable of from the computer hardware. So it's better to use the latest hardware components in combination not only with the latest versions of operating systems, but even with diagnostic systems and UEFI controls that have replaced the BIOS that has served for so long.
Hardware virtualization provides virtual machine performance that is almost the same as that of a non-virtualized machine, and this technology is necessary to be able to work with virtual machines on your computer. By default, virtualization may be disabled on some. In this article, I will tell you how to find out if your processor supports Intel VT-X technology (Intel processors) or AMD-V (AMD processors). Also from this article you will learn how to enable Intel VT-X and AMD-V technology.
Intel VT-x This is hardware virtualization from Intel. To find out if your processor supports technology Intel VT-X download the CPU-Z program . . After starting in the program window, we look at the technologies that your processor supports:
If there is VT-X in the “Instruction” column, then your processor supports virtualization.
AMD-V
AMD-V is a hardware virtualization technology from AMD. To check if your processor supports this technology, we also need the CPU-Z program, run it and look at the “instruction” item. If AMD-V is there, then your processor supports virtualization:
Enabling VT-X/AMD-V in Bios
Boot into Bios. In BIOS, everyone's picture may be different, we need to find a mention of virtualization (intel virtualization technology or virtualization) and enable this feature. In my case it was like this:
Save bios settings and reboot. That's it, virtualization is on!
Enabling VT-X/AMD-V in UEFI
In the case of UEFI, I had to go to the Advanced > CPU configuration tab and enable virtualization there:
After enabling VT-X and AMD-V, you will be able to create virtual machines on your computer
We turn on hardware virtualization of central processors, AMD technologies - AMD-V and Intel - VT-X. Details on how to check if virtualization is supported by the processor and how to enable virtualization in the BIOS. The technology is checked and turned on simply ....
Virtualization is - virtualization means a processor architecture with the ability to simulate hardware (virtual guest systems) using software methods. Virtualization technology makes it possible to run several operating systems (virtual OS) on one real physical computer, with isolated separated computing processes, with dedicated logical resources, partly - processor power, RAM, file subsystem from a common pool.
In simple words, virtualization allows the user to run diverse virtual machines on one physical personal computer with different types of operating systems (Windows, Android, Linux, MacOS X) or the same, with any set of programs. Most in demand at the moment among gamers, allows you to launch and speed up .
How to check if virtualization is supported and enabled.
For those who are afraid to enter the BIOS, you can check whether the virtualization technology is supported by the processor or not and whether it is enabled in the BIOS, you can use the SecurAble program. The utility is free, does not require installation - the portable version, literally in two clicks - launched, learned the result, closed. You can download the program by going to SecurAble official website or download via direct link from - of. site.
SecurAble options:
1. Parameter value Maximum Bit Length indicates the maximum available bit depth of the system 32-bit or 64-bit.
2. Values Hardware D.E.P- technology responsible for security, implemented to prevent the launch of malicious code.
3.Option hardware virtualization- the parameter can give four values:
Yes- virtualization technology supported by the processor - enabled;
no- virtualization is not supported by the processor;
Locked On- enabled and supported, but cannot be disabled in the BIOS;
Locked Off- there is support for the technology, but it is disabled and cannot be enabled in the BIOS.
The inscription Locked Off is not always a verdict - flashing the BIOS can fix the situation.
How to enable virtualization in BIOS.
Virtualization Technology is responsible for enabling hardware virtualization in the BIOS. To disable the option or enable virtualization in the BIOS, we send the PC to reboot. When the first signs of loading appear, click on the keyboard key "F2" or "Delete" (different versions of BIOS), look for a hint at the bottom of the screen at the start.
We go to the section "Advanced BIOS - Features", we find the option "Virtualization" or "Advanced" → "CPU Configuration", the option "Intel Virtualization Technology".
We move using the keyboard arrows (in BIOS UEFI with the mouse), press "Enter", change the parameter for "Virtualization" from "Disabled" (disabled) to "Enabled" (enabled). Virtualization was enabled in the BIOS, it remains not to miss one important click - do not forget to press the "F10" button, which corresponds to the value - save the settings (Save).
And most importantly, remember - Virtualization Technology only creates an environment for Android emulators, operating systems and does not affect the actual hardware performance in any way (does not make the computer powerful). Work hard first , choosing components wisely and only then demand something from him.
Today it is known that support for hardware virtualization Intel VT-x/VT-d and AMD-V necessary for the operation of virtual machines, such as virtual box And VMware Workstation, as well as for the operation of so-called emulator programs for mobile operating systems, for example, for Android OS.
Nowadays, almost all modern computers have support for this technology, but of course there are those that do not. And in order to find out if our processor has support for this technology, we will first go to BIOS our computer and see if there is a setting that interests us. I added to the article a few examples of what the virtualization enable item looks like in different BIOS versions. Basically enabling this option is on the tab advanced, further, as you can see in the picture below, under the name and hides the proof that this computer supports this technology.
In this version BIOS go to tab advanced BIOS features where we also see in paragraph virtualization support for this technology.
And here at paragraph advanced BIOS features it can be seen that hardware virtualization is supported by the processor.
Well, the last option, where in the tab advanced in step secure virtual machine mode, we can also include this technology.
But there are also such cases that in the BIOS of our computer there is no option to enable hardware virtualization secure virtual machine mode or intel virtualization technology, although they say that the processor that is in your computer supports this technology. In order to make sure of this, we will be helped by a small utility called SecurAble, which will accurately show whether our processor supports hardware virtualization. We go to the official website of the manufacturer at the link https://www.grc.com/securable.htm, where at the bottom we click on the item download now. The download will start, after we launch the program, you do not need to install it, since this is a portable version.
After starting, the program will immediately show information about whether your processor supports or does not support virtualization technology. You can see this in the third block. As you may have guessed, if there is an inscription yes so there is support.
If written Locked OFF, this means that there is support for this technology, but it must be enabled. And it turns on, as we already know, in BIOS-e of our computer.
Well, if the block has an inscription NO, means hardware virtualization technology is not supported by your processor.
ABOUT leave your opinion about this article, and of course, ask your questions if something suddenly went wrong for you.
Thanks for attention!
In general, the other day I encountered such a problem as the inability to run guest operating systems on a virtual machine. More precisely, I could not run exactly 64-bit systems, although my processor quite supports such ones. Also, there was a problem with starting a Linux distribution from a USB flash drive, the same problem appeared.
Having rummaged one night on the Internet, I found a certain parameter Virtualization Technology, which includes virtualization technology. It is enabled in the BIOS. Thus, if you activate it, then you can easily use guest systems on virtual machines such as, for example, others. Basically, this function does not affect the operation of the system; by default, it is disabled (Disabled).
It may have different names in different BIOS systems, for example, Virtualization, Vanderpool Technology, VT Technology.
So, hardware virtualization, we realized that it provides support with specials. processor architecture. There are two virtualization technologies: AMD-V and Intel-VT.
AMD-V- this technology also has the abbreviation SVM (Secure Virtual Machines). IOMMU I/O technology. It turns out that it is even more efficient than Intel-VT.
Intel-VT (Intel Virtualization Technology)– this technology implements virtualization of real addressing. May be abbreviated as VMX (Virtual Machine eXtension).
I will not describe what these technologies mean in detail, since a lot of information has been written about this on the Internet.
How to enable Virtualization Technology?
Well, actually everything is very simple here. First you need, and then find the item Virtualization Technology, it can be called a little differently, as I wrote above, for example.
In different types of BIOS, the item can be located in different places, for example, in the AWARD BIOS and Gigabyte motherboards, you will see it as soon as you get into the BIOS, to enable it, you just need to move the parameter to the position "Enabled".
In the BIOS of American Megatrends Inc, this technology is enabled by default and is located in the tab "Advanced". There you can enable or disable it.
The BIOS of some HP (Hewlett-Packard Company) notebooks and BIOS InsydeH20 Setup Utility disable the virtualization feature. To activate it, you need to go to the tab "System Configuration".

Virtualization may be needed for those users who work with various emulators and / or virtual machines. Both of them may well work without this option enabled, but if you need high performance while using the emulator, then you will have to enable it.
Important warning
Initially, it is advisable to make sure that your computer has support for virtualization. If it is not there, then you risk simply wasting your time trying to activate through the BIOS. Many popular emulators and virtual machines warn the user that his computer supports virtualization, and if you enable this option, the system will run much faster.
If you did not get such a message when you first started some emulator / virtual machine, then this may mean the following:
- Virtualization is already enabled by default (this is rare);
- The computer does not support this setting;
- The emulator is not able to analyze and notify the user about the possibility of connecting virtualization.
Enabling virtualization on an Intel processor
Using this step-by-step instruction, you can activate virtualization (relevant only for computers running on an Intel processor):
Enabling virtualization on an AMD processor
The step-by-step instruction looks like this in this case:
It is not difficult to enable virtualization on a computer, for this you just need to follow the step-by-step instructions. However, if the BIOS does not have the ability to enable this feature, then you should not try to do this using third-party programs, as this will not give any result, but it may worsen the computer's performance.
We are glad we were able to help you resolve the issue.

Virtual Secure Mode (VSM) in Windows 10 Enterprise
Windows 10 Enterprise (and this edition only) has a new Hyper-V feature called Virtual Secure Mode (VSM). VSM is a secure container (virtual machine) running on a hypervisor and separated from the host Windows 10 and its kernel. Security-critical system components run inside this secure virtual container. No third-party code can run inside the VSM, and the integrity of the code is constantly checked for modification. This architecture allows you to protect data in the VSM, even if the kernel of the host Windows 10 is compromised, because even the kernel does not have direct access to the VSM.
The VSM container cannot be connected to the network and no one can gain administrative privileges on it. Inside the Virtual Secure Mode container, encryption keys, user authorization data, and other information that is critical in terms of compromise can be stored. Thus, an attacker will no longer be able to penetrate the corporate infrastructure using locally cached domain user account data.
The following system components can run inside VSM:
- LSASS (Local Security Subsystem Service) is a component responsible for authorization and isolation of local users (thus the system is protected from “pass the hash” attacks and utilities like mimikatz). This means that passwords (and/or hashes) of users registered in the system cannot be obtained even by a user with local administrator rights.
- Virtual TPM (vTPM) is a synthetic TPM device for guest machines that is required to encrypt the contents of disks
- OS code integrity control system - protection of the system code from modification
To be able to use the VSM mode, the following hardware requirements are imposed on the environment:
- UEFI, Secure Boot and Trusted Platform Module (TPM) support for secure key storage
- Support for hardware virtualization (at least VT-x or AMD-V)
How to enable Virtual Secure Mode (VSM) in Windows 10
Let's look at how to enable Virtual Secure Mode in Windows 10 (in our example, this is Build 10130).
Checking the operation of VSM
You can make sure that the VSM mode is active by the presence of the Secure System process in the task manager.
Or by the event “Credential Guard (Lsalso.exe) was started and will protect LSA credential” in the system log.
VSM security testing
So, on machines with VSM enabled, we register under a domain account and run the following mimikatz command from under the local administrator:
mimikatz.exe privilege::debug sekurlsa::logonpasswords exit
We see that the LSA is running in an isolated environment and the user's password hashes cannot be retrieved.
If the same operation is performed on a machine with VSM disabled, we get an NTLM hash of the user's password, which can be used for "pass-the-hash" attacks.
