We enable hardware virtualization of central processors, AMD - AMD-V and Intel - VT-X technologies. Learn more about how to check whether virtualization is supported by the processor and how to enable virtualization in the BIOS. The technology is checked and activated simply...
Virtualization is — by virtualization we mean 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, some of them are processor power, volume random access memory, file subsystem from the common pool.
In simple words, virtualization allows the user to run diverse virtual machines with different types operating systems (Windows, Android, Linux, MacOS X) or the same, with any set of programs. Most in demand at this moment for gamers, allows you to launch and speed up .
How to check whether virtualization is supported and enabled.
For those who are afraid to enter the BIOS, you can check whether the processor supports virtualization technology or not and whether it is enabled in the BIOS, you can use the SecurAble program. The utility is free and does not require installation - portable version, literally in two clicks - launched, found out the result, closed. You can download the program by going to SecurAble official website or download via direct link from - office. site.
Securable parameters:
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, introduced to counter the launch of malicious code.
3. Option Hardware Virtualization— the parameter can produce four values:
Yes— virtualization technology is 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— the technology is supported, but it is disabled and cannot be enabled in the BIOS.
The Locked Off message is not always a death sentence - flashing the BIOS can correct 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 BIOS), look for a hint at the bottom of the screen at startup.
Go to the “Advanced BIOS - Features” section, find the “Virtualization” or “Advanced” → “CPU Configuration” option, “Intel Virtualization Technology” option.
We move using the keyboard arrows (in BIOS UEFI with the mouse), press “Enter”, change the “Virtualization” parameter from “Disabled” to “Enabled” (enabled). Virtualization has been enabled in the BIOS, all that remains is not to miss one important click - don’t forget to press the “F10” button, which corresponds to the value - save settings (Save).
And most importantly, remember - Virtualization Technology only creates an environment for Android emulators and operating systems and does not affect the actual performance of the hardware in any way (it does not make the computer powerful). Work hard first , choosing components wisely and only then demand something from it.
Good afternoon, readers of my blog. There is one useful feature for AMD and Intel processors. Intel calls it intel vt x virtualization technology, and AMD calls it AMD-V virtualization technology. It happens that you need to find out whether your processor supports this technology; in this article I will tell you how to check your processor for the presence of virtualization technology.
In my article about where you can download it for free, I mentioned that in the requirements for it on your computer, the processor must have intel vt x or AMD V virtualization technology. So, let's see how to find out if your processor has such a function.
There are several ways to check the availability of this technology. The first is to look at the list below, and if your processor is there, then the intel vt x virtualization technology is on your processor. If you do not know the model of your processor, then method number 2 below will suit you. List: 
AMD processors have their own list of models that support virtualization technology. If you do not know the model of your processor, then method number 2 below will suit you. List: 
There is one wonderful program called HavDetectionTool. However, there is one drawback: it only works on Windows XP, Vista and 7. If you run on WIndows 8, 8.1, or 10, you will receive the following error: 
So, if you have Windows 7, run HavDetectionTool.exe (you can download
Hi all! Now we will talk about such a confusing topic, which sounds like this: how to enable virtualization in the BIOS. Let’s also try to figure out why, in general, this needs to be done.
So, my friends, in simple terms, this technology is needed for the operation of various software virtual machines and emulators. With its help, the performance of such software increases significantly.
This means that, without the use of third-party programs, we can install and test operating systems on virtual machines created for this purpose. In this article we will learn how to launch it. After rebooting and logging in, we launch the control panel.
Click on the magnifying glass and enter the panel. When the Control Panel window appears on your monitor, go to the “Programs” tab. To do this, select its checkboxes by selecting them with the mouse. When the entire process is successful, the system will display a message indicating the completion of the changes.
But let's start with the fact that the reason for writing this article was the following message that one of the very Androids issued upon startup. Let's look and analyze:
And this is nothing more than a call to enable this very damn virtualization. After all, this technology is abbreviated as VT-x or AMD-V. It all depends on which manufacturer’s process it is used in.
Click right click mouse over the pop-up menu and select "Run as administrator". Then enter the command. There is still a computer reboot. After rebooting and logging in, we will launch the control panel. Go to the "Programs" tab.
To enable these features, select the check boxes by clicking them. To complete the installation, we must restart the computer as soon as possible. Virtualization can save you money on upgrading your computing infrastructure. Instead of purchasing multiple computers, all systems can run simultaneously.
Well, let's try to take the first steps in the right direction. First of all, we need to enter the BIOS in order to actually activate this very function. Therefore, from words to deeds.
Of course, it’s worth mentioning right away that each manufacturer has a BIOS entry and sections in it. But for clarity and as an example, everything further actions will be shown on your Lenovo laptop.
This is ideal for testers or technical support. This way of working also allows you to make optimal use of your PC's resources, which are usually idle for most of the time. Working in a virtual environment also improves security.
If you want to limit its operation in one direction, for example to improve security, you will do this in the "Shared Storage" field on the "Advanced" tab. The default bidirectional setting allows you to copy data from the base system to the virtual system and vice versa. On the same tab, you can also move the virtual machine toolbar from the bottom edge of the screen to the top. All you have to do is select "Show" at the top of the screen.
So, let's go in and immediately go to the "Configuration" section. There we find the “Intel Virtual Technology” item we need so much and activate it by selecting the “Enable” value:
That's all, now virtualization is enabled in the BIOS, you can use it. All that remains is to save the changes made. To do this, go to the "Exit" section and select the "Exit Saving Changes" item:
Virtual hardware configuration is performed in the “System” section. In the Motherboard tab, you can increase the amount of virtual memory assigned to the main memory slider. You will also enter a value in the box on the right. Remember that it is not recommended to record more than half of the used physical memory. Below, using the arrows, you will change the starting order. If you want to use a virtual network adapter for this purpose, check the Network checkbox.
You'll change the number of virtual processors on the Processor tab. If your processor supports hardware virtualization, you can enable it in the program by selecting the appropriate options on the Accelerator tab. Graphics card memory and graphics acceleration are determined in the Video tab under Display. In the same section, but on the “Remote Desktop” tab, you can launch the function. This gives you the ability to remotely manage a virtual system over a network connection.
But in conclusion, let's talk a little about one not very pleasant nuance that you may encounter, including the technology described above. The thing is that some manufacturers block it by default.
That is, the computer hardware can support virtualization, but the BIOS will not be able to activate the desired item. In this case, alas, get off little blood will not work.
We save the changes. I am interested in backup technologies and security issues. Most newly shipped server machines are now configured in Green mode, which reduces power consumption at the cost of significantly reducing the performance of the newly purchased server. It is available on many Thomas-Krenn servers.
You will receive an error message: "Virtualization hardware support is not available." The selected setting is locked and cannot be changed while the system is running. After saving the configuration, the server must be disabled and then enabled. The right column contains the following help text.
There is a lot of information on the Internet about how to remove such a block. But we must say right away that it is clearly not designed for the average user, since it requires specific computer knowledge:
And our story about enabling virtualization is coming to an end. If you have any questions, please ask them in the comments to the article. And now we invite everyone who is curious to watch a very interesting video.
Once the setting is changed, one power cycle will occur. A few years ago, someone noticed something very obvious: companies all over the world had several dedicated servers for specific purposes. But what is most annoying? Sounds great, you just need to write the software!
The application installed inside such a "pretend" computer is convinced that it is running on real physical hardware, so there is no compatibility problem. However, now is the time for reflection and time to turn plans into action. Genius and the best possible. This system verifies the legitimacy of computer components.
How to enable virtualization in BIOS? This was the question asked a large number of users of personal computers. Some people have probably heard of this technology, but do not understand what benefits it can provide, or what it actually involves. These issues will be discussed in this article.
Before telling you how to enable virtualization support in BIOS, you need to explain what it is. IN computer technologies this term refers to hardware modeling using software methods. Thanks to virtualization technology, you can create a number of virtual computers, that is, those that are simulated programmatically. In this case, only one sufficiently powerful physical computer is used.
However virtual machine is identified, for obvious reasons, as other hardware than a physical computer. This leads to reports of systemic illegality. For example, in my case it is a disk with a number. In my case this command looks like this. It is also possible to select only one or a few partitions rather than the entire disk.
If we don't do this, our machine won't start. This requires direct disk access. The following guide will walk you through the installation process, step by step. We will make our computer pretend to be another, new computer - we will launch a virtual machine. After this, your original computer will be undamaged and you can use it the same way as before.
What's good about virtualization? Here are its main advantages:
In order to create virtual systems, special software called a hypervisor is used. But due to some features of older processors built on Intel architecture, the hypervisor could not use their computing power as efficiently as possible to create virtual machines.
The suggested installation method is probably the safest. It is possible, however, that you have nothing to warn and try to try. Even when the features have been enabled, virtualization features are not available in the operating system. This will result in an error message indicating that hardware virtualization support is not available.
Only after this the new setting will take effect. After saving the configuration settings, the server must be turned off and on again. The following useful information will appear in the right column of this view. A screenshot similar to the message on the screen will look like this.
For this reason, leading companies developing processors for personal computers, created hardware virtualization technology. It can optimize the operation of processors in such a way as to significantly increase the efficiency of the software for this process. Intel's hardware virtualization support technology is called Intel-VT, while AMD's is called AMD-V.
The basis is the division of the processor into guest and monitor parts. For example, when switching from the host OS to the guest OS, the processor automatically switches to the guest state. At the same time, it shows the system the register values that it wants to see and that it needs for stable operation. Thus, the processor is a “deceiver”, which relieves the system of all sorts of tricks. The guest OS works directly with the processor, making the virtual machine run much faster than on a PC without virtualization support.
Since hardware virtualization is integrated into the central processor, in order for the user to take full advantage 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 has the opportunity to enable or disable it in the settings. It is necessary to take into account that there are chipsets for which are based on AMD processors, and in which it is not possible to disable support for this technology.
To enable or disable this option in the BIOS there is special function, which is called - Virtualization Technology. Typically, this option is found in the CPU or Chipset related sections.
So, how to enable virtualization in BIOS? Very simple. Typically, setting the value to Enabled allows you to enable the technology, and setting it to Disabled allows you to disable it. Please keep in mind that activating the setting only affects the performance of virtual computers that run within the hypervisor. For the performance of all programs operating system there is no impact.
Different manufacturers use their own settings, but it is still not difficult to enable virtualization in the BIOS (Asus, Lenovo and others have similar settings).
We found out how to enable virtualization in the BIOS. This technology is a very powerful tool that allows you to expand the capabilities of computers and use the available hardware much more efficiently. 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 implement the technology into the hardware. And only BIOS has direct access to it.
When working with software product VirtualBox virtualization, problems and malfunctions often arise associated with the installation of a particular operating system on a virtual machine. The reasons for errors in operation may be different and with one of them, which states that "hardware acceleration (VT-x AMD-V) is not available on your system", we will understand in this article.
IN in this case, this problem arose when installing the operating system windows systems 8, although when Windows 7 was installed, such an error did not occur. How can we decide this problem? Let's find out below.
So, first of all we need to make sure that the processor supports the function VT-x/AMD-V, for this read the article How to check if your processor supports hardware virtualization Intel VT-x/VT-d and AMD-V. And to enable it, you need to go to BIOS motherboard. To do this, reboot the computer and go to the BIOS of our system.
In order to go to BIOS, we need to press a key when turning on the computer Delete on keyboard. (If it does not enter using the key delete try it F1, F2) When you turn on the computer home screen you can usually see which key leads to BIOS.
As a result, we get into the BIOS of our computer. Next, select the tab " Advanced". There we see the tab " CPU Configuration" select it and press " Enter"
We get to the configuration menu, where we see the tab "Secure Virtual Machine Mode" opposite is the value "Disabled" what does disabled mean, we just need to enable it, to do this, click on the tab and select the value "Enabled".
As we see in the figure, the value has changed, now we need to save the changes made.
To save the changes made, go to the tab "Exit" then select the tab "Exit & Save Changes". In the window that opens where we are asked to save the changes made, click "OK" and wait until the computer reboots.
Next, open the VirtualBox program, go to " settings" the system that you wanted to install, in my case it is Windows 8.1. Click on the tab " system", Further "acceleration", check the boxes next to the items indicated in the picture and click "OK."
All! The error no longer appears, you can begin the installation.

Thank you for your attention!
Virtualization may be necessary for those users who work with various emulators and/or virtual machines. Both of them can work quite well without enabling this parameter, however, if you require high performance while using the emulator, you will have to enable it.
Initially, it is advisable to make sure whether your computer supports virtualization. If it is not there, then you risk simply wasting your time trying to activate it through the BIOS. Many popular emulators and virtual machines warn the user that his computer supports virtualization and if you enable this parameter, the system will work much faster.
If you do not receive such a message when you first launch an emulator/virtual machine, this may mean the following:
Using these step-by-step instructions, you can activate virtualization (only relevant for computers running on Intel processor):
The step-by-step instructions in this case look similar:
It’s easy to enable virtualization on your computer; all you need to do is follow step by step instructions. However, if the BIOS does not have the ability to enable this function, then you should not try to do this using third party programs, as this will not give any result, but may worsen the performance of the computer.
We are glad that we were able to help you solve the problem.

Windows 10 Enterprise (and only this edition) has a new Hyper-V component called Virtual Secure Mode (VSM). VSM is a protected 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 be executed inside 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. Encryption keys, user authorization data and other information critical from the point of view of compromise can be stored inside the Virtual Secure Mode container. 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:
To be able to use VSM mode, the environment must meet the following hardware requirements:
Let's look at how to enable Virtual Secure Mode in Windows 10 (in our example, Build 10130).
You can make sure that 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.
So, on machines with VSM mode enabled, we register under the domain name account and as a local administrator we run the following mimikatz command:
mimikatz.exe privilege::debug sekurlsa::logonpasswords exit
We see that the LSA is running in an isolated environment and user password hashes cannot be obtained.
If the same operation is performed on a machine with VSM disabled, we obtain an NTLM hash of the user's password, which can be used for “pass-the-hash” attacks.
