Virtualization technology how to enable in BIOS. Enable virtualization support

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 — 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, some of which include processor power, RAM, and a file subsystem from a common pool.

In simple words, virtualization allows the user to run diverse virtual machines with different types of operating systems (Windows, Android, Linux, MacOS X) or the same ones with any set of programs on one physical personal computer. Most in demand at the moment among gamers, it 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, does not require installation - the 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 BIOS versions), look for a hint at the bottom of the screen at the start.

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.

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.

Right-click 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 at the same time.

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, all further actions will be shown on a 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 write 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 required item. In this case, alas, you won’t be able to get away with little blood.

Possible errors in the event log

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 offer 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 question was asked by a large number of personal computer users. 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.

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 modeling hardware using software methods. Thanks to virtualization technology, it is possible to create a number of virtual computers, that is, those that are simulated in software. In this case, only one sufficiently powerful physical computer is used.

Create a virtual disk

However, the virtual machine is identified, for obvious reasons, as a different piece of hardware than the 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.

Key Benefits

What's good about virtualization? Here are its main advantages:

Increases the efficiency of hardware use.
Material costs are reduced.
Resource allocation is optimized.
Work safety becomes higher.
Simplified administration.
Increased reliability.

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 have created hardware virtualization technology. It is capable of optimizing 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.

Operating principle

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.

Technology 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.

How to enable virtualization in BIOS?

To turn this option on and off, the BIOS has a special function 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. It must be kept in mind that activating the setting only affects the performance of virtual computers 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 is still not difficult to enable virtualization in the BIOS (Asus, Lenovo and others have similar settings).

Conclusion

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.

Conclusion

Virtualization technology allows you to create several virtual computers with their own operating systems on one physical computer. Guest operating systems will use the resources of the real PC allocated to them within the established limits. In this case, there is no need to partition the disk and there is no danger of damaging the bootloader. The user's personal data is not affected and is safe. If you are interested in these opportunities, stay tuned. Today we will tell you how to enable virtualization in Windows 10.

A Microsoft-developed hypervisor called Hyper-V is included as an optional component. It can only be used in x64 bit OS Windows 10 Enterprise or Pro. In a corporate environment, Microsoft even recommends specific HP and Lenovo laptops. This option is not available to users of the Home edition and all x32 bit systems.

You can quickly find out the parameters of installed Windows using the keyboard shortcut Win + X. In the expanded menu, select the item marked with a frame.

The window that opens contains two blocks of information. In the first, we look at the amount of installed memory and bit depth. Hyper V requires at least 4 GB of RAM. In the second block we pay attention to the OS release.

According to system parameters, the computer is suitable for installing and running a Microsoft VM. Additionally, Hyper-V requires the processor to support nested SLAT paging. Intel implemented it in the Core i3/5/7 line, and AMD since the first 64-bit Opterons. The processor model is indicated in the device characteristics, so there is no need to check it in the BIOS or UEFI. We can verify the support of Hyper technologies using the command line. Enter the “systeminfo” command and look for the data block indicated in the screenshot.

As you can see, all the necessary requirements have been met and we performed the check without going to the BIOS. Having made sure that the hardware configuration is suitable for using the virtual machine, we can proceed to installation.

Installation

Hyper-V is a component of the operating system. It cannot be downloaded and installed separately. You can only enable use in a Windows environment. Let's look at several options for connecting Microsoft Virtual Machine.

Graphics mode

Let's start by using the graphic mode, as it is the most familiar to users.

Using the Win + R key combination, open the “Run” dialog box and enter the “control” command in the text field as shown in the screenshot.

The result of our actions will be the appearance of the classic Windows Control Panel. We look for the specified item and open it.

In this window we will use the navigation menu, which is responsible for working with operating system components.

Turn on Hyper-V. Expand the “Hyper” branch and make sure that all its components are checked. We complete the work in this section by clicking the “OK” button.

Windows internally searches for and installs the ordered components.

Once you have completed making changes to the software configuration, the system will prompt you to reboot.

This completes the installation and the PC is ready to use the built-in virtualization tools.

Command line

You can also install hypervisor components using command line capabilities.

Open the Power User menu and launch PowerShell or CMD shell as administrator.

Enter the following line in the window that opens:

Enable-WindowsOptionalFeature -Online -FeatureName:Microsoft-Hyper-V –All

Windows processes the received command to install additional components.

Finally, we will be asked to confirm the changes made and reboot. Enter the English letter “Y” in any case.

The computer will immediately exit graphical mode and display the standard update window. The system will start with Hyper-V enabled.

The last method involves using the Windows Image Deployment and Management Tool.

Launch the command line with administrative rights. Enter the following line:

DISM /Online /Enable-Feature /All /FeatureName:Microsoft-Hyper-V

After installing the components, DISM asks for confirmation.

Entering the letter “Y” causes the PC to immediately reboot and perform the initial setup of Hyper-V.

Usage

Once the installation is complete, you can begin creating a new virtual machine.

The new component is located in the Administrative Tools section of the Start menu.

Hyper-V Manager is a standard Windows management console. Enabling and configuring operations is done in the Action area. Select the marked item to launch the wizard.

A three-item selection menu will open. Select the one indicated by the frame.

The first window is informational. By placing a checkmark in the specified place, you will no longer see it during subsequent launches. To create a machine with your own configuration, select the button marked with a frame.

Here we set the name of the machine being created and can change the storage location for its files.

The generation should be selected based on the bit depth of the OS to be installed. For 32-bit versions we leave the first, but modern distributions belong to the second.

The size of the allocated memory depends on the physical capabilities of the PC. The simplest solution would be to allocate 2 GB (2048 MB). This is the minimum amount required to run 64-bit Windows. It is enough to install any version of Linux.

In the network settings, open the drop-down menu and select the specified option. VM Manager will automatically configure the connection for the virtual machine using your current Internet connection.

The disk size that will be used for installation can be limited to 32 GB. This is enough to run a guest OS with a set of programs.

We agree with the proposal to install the guest system later. This can be done using DVD media or an ISO image.

The virtual machine is ready. To disable Hyper-V and remove guests, you must disable this Windows feature in Control Panel.

Alternative

Windows Home owners who do not have access to Hyper-V can use a free alternative solution from Oracle. Unlike the Microsoft product, the VirtualBox application runs on 32-bit systems, has more features and is less resource-demanding. It does not require a special set of processor instructions.

Almost all existing operating systems will run in VirtualBox, which cannot be said about Hyper-V. In it, the choice is limited to several versions of Windows, and more recently also Linux.

In conclusion

To use virtual machines comfortably, do not forget that they consume physical computer resources. Ideally, a PC should have 8 GB of memory to ensure simultaneous operation of the current and guest OS with running applications.

To help users who want to better understand Windows 10 virtualization settings, below are links to videos.

Hello everyone) In your motherboard BIOS you can find something like Intel Virtualization Technology and then you will immediately have questions about whether to enable it or not? What is this actually responsible for, what the hell, and if you turn it on, then maybe the computer will work better? Yes, there can be a lot of thoughts, when I was hacking away at the computer, studying everything, there were also a lot of thoughts, like, what will happen if...)

In short, I’ll say right away, I know what Intel Virtualization Technology is, but I’ll also say that in most cases you don’t need to enable it. Neither you nor your friends, well, something tells me that you don’t really need this technology. Why do you think this? Okay, I'll tell you. This means Intel Virtualization Technology is a virtualization technology so that some software can work directly with the processor, so to speak.

You are probably asking, what other software? Here I mean computer virtualization programs, in simple terms these are virtual machines, the most popular so far are the paid VMware Workstation (by the way, there is a free option - VMware Player) and absolutely free VirtualBox. They say that the first is a virtual machine, and the second is an emulator. But I don’t really understand the difference)

Here's what this option looks like in the BIOS itself:

So, ordinary users don’t need Intel Virtualization Technology for nothing, it doesn’t do anything, it doesn’t add any power. You might be wondering what a virtual machine is, what is it even? This is a program that simulates a computer, but it is virtual. Here you can install Windows into it, add or remove a hard drive, set the number of processor cores, and specify the amount of RAM. Do you understand? But for such a virtual computer to work quickly, you need some kind of virtual access to the processor, and Intel Virtualization Technology is needed to provide this access)

As you already understand, this technology is found in Intel processors, but AMD also has its own, it’s called AMD-V and it’s about the same as Intel’s. Virtual machines without this technology will work terribly slowly. In general, Intel Virtualization Technology is divided into two parts, these are VT-x and VT-d, that is, if you see such designations, now you know what it is. I already wrote about what VT-x and VT-d are here, so you’re welcome to read.
