Virtualization allows you to encapsulate the internals of operating systems or parts of them within virtual hardware and software. In other words, create a virtual space that will be real from the point of view of the operating system running in this space. This is exactly what virtual machines do for Windows 7, Linux and Mac OS X. Virtualization also allows you to simulate devices that are not even on your computer.

Note: In a sense, virtual machines allow you to create a computer within a computer.

There are two important aspects of machine virtualization:

interaction between a physical host (computer) and a virtual host
interaction between the operating system running in the virtual space and the hardware used

Virtualization software, namely virtual machines for Windows 7 (Linux, Mac OS X), is typically a regular operating system application or service that allows you to create hosts. A host is any physical machine (computer). Within virtualization software, the operating system runs on a host similar or identical to the actual host, called a virtual machine. For convenience, the operating system running in a virtual machine is called a guest operating system.

In addition, there are various virtualization methods that affect not only the implementation of applications for creating virtual machines, but also the capabilities provided to guest systems. There is conventional emulation, in which hardware and software calls pass through an intermediate layer. There is also para-virtualization, where part of the actions inside the virtual machine takes place on real hardware, while the other part passes through an intermediate layer. There is also virtualization at the system level, when each guest system boots in a special kernel, which allows you to run only similar versions of the operating system.

Some of these methods can be performed on the fly, without significant changes to the actual host and its operating system. Others require the host to be rebooted into a special instance of the operating system that supports virtualization. Others use special hosts that support and are designed for virtualization at the hardware device level. The latter are also known as bare metal virtualization methods (although this is not entirely true, since some software kernel is still used).

The virtualization software that manages the creation and operation of virtual machines, as well as the allocation and limitation of the resources provided, is often called a hypervisor. Some virtualization applications can also use special processor extensions to improve the performance of virtual machines. The presence of such extensions is called hardware support for virtualization. Examples of this support are VT-X (Intel) and AMD-V (AMD) technologies.

What is not virtualization and virtual machine?

Some people like to call virtualization programs (virtual machines) anything that creates a layer of abstraction between the operating system and some of the running processes. For example, there is Sandboxie, which allows you to isolate browsers from the system (see browser protection utilities). Some programs allow you to freeze the state of the system so that it cannot be changed. Others also allow you to use the so-called shadow mode, in which all programs run normally, but any changes are canceled when you restart the computer.

Of course, all of these programs provide various benefits, but they are not considered virtualization technologies and are not virtual machines because they do not simulate system calls, and they do not allow guest operating systems to run on top of the current system. Such programs only create additional layers of separation, mainly to increase the level of security. If we continue the topic of security, then...

Why use virtualization and virtual machines?

If security comes first for you and is the first thing you think about in any situation, then virtualization (the use of virtual machines) can certainly help you with this. But don’t assume that virtualization is mainly used for security. Its initial goals are: testing, cost reduction, flexibility, legacy product support, and education. Increasing the level of security is just a pleasant bonus, which also has many pitfalls.

Note: Although virtualization allows you to isolate one operating system from another, there are still ways to get from the guest system to the main one.

What is needed to run virtualization technology and virtual machines?

The first thing to consider is the physical host. Depending on the type of virtualization software (virtual machines), completely different hardware and operating systems may be required. Virtualization does not imply any single solution that will run wherever needed. Virtual machines need to be selected for the system (Windows, Linux, Mac) and for the hardware (hardware). In addition, the host must have the necessary .

So if you are going to run guest operating systems on top of your system, you will need additional resources to run them, such as a processor and RAM. For example, if your computer only has 2 GB of RAM and you want to run a guest system on Windows 7, then you will have to severely limit resource usage on the real system in order for the virtual machine to function properly. Unless, of course, you're trying to run Windows XP with 256 MB of memory. However, if you have 16 GB of RAM, then you can run more than one guest system without experiencing any shortage of resources.

Pros: Easy to install and use.

Cons: Limited functionality. Does not support snapshots or directory sharing.

Virtual machine for Windows 7, Linux and Mac OS X - VirtualBox

VirtualBox is another cross-platform virtual machine creation program for Windows 7 and above, as well as Linux and Mac systems, currently owned by Oracle. VirtualBox is similar to VMware Player, but has more features, including a more advanced networking stack, unlimited snapshots, some OpenGL and DirectX support, and much more. The app is easy to install and just as easy to use. You can also use the command line for automatic deployment. VirtualBox also supports USB and shared directories. There is also a portable version of VirtualBox. However, there are also disadvantages. You cannot take screenshots of guest systems. Disk management is a bit confusing.

Audience: beginners and experienced users.

Pros: Easy to install and use, many features.

Cons: No support for screenshots, importing existing machines is difficult, disk management is not intuitive.

VMware ESXi hypervisor for creating virtual machines

ESXi is a bare metal hypervisor with reduced functionality compared to ESX. The app requires a host and can be controlled from the console (the console is locked by default, but you can enable it manually). You will not be able to take screenshots or record video of the screen of your virtual machines. Transferring and cloning guest systems can only be done manually. But what you get is memory sharing for improved RAM efficiency, powerful monitoring and management, and command line access via SSH (when unlocked). You can also install VMware Tools to improve the performance of virtual machines. Para-virtualization is also supported by ESXi.

Pros: Powerful, advanced virtual machine capabilities.

Cons: Requires a host and a lot of resources. Not easy to install and run.

Virtual machine for Unix/Linux - Kernel-based Virtual Machine (KVM)

KVM supports virtualization only for UNIX-like operating systems (Linux). The application can be run on any hardware or in emulation mode, but without processor extensions the performance will be terrible. KVM is designed to be used via a console. But, it has a decent management interface that allows you to start and stop virtual machines, take screenshots and much more. The interface is known as the Virtual Machine Manager (VMM) and is also used to manage Xen virtual machines (see below). Supports local and remote control. There is a known conflict with VirtualBox, but it can be resolved relatively easily

Audience: advanced users and professionals.

Pros: Full control and flexibility, very high performance under the right conditions.

Cons: UNIX-like systems only. Requires hardware virtualization extensions for normal execution. Emphasis on the command line. Not easy to install and run.

Virtual machine for Unix/Linux - Xen

Xen is another application for virtualizing UNIX-like operating systems (Linux). It must boot in its own kernel instance. The emphasis is on the command line. But, you can also use VMM. Officially, Xen has been supported by OpenSUSE for many years and was recently added to the main kernel release branch. Xen can run in hardware-assisted or para-virtualization mode. However, for para-virtualization, Xen is extremely problematic to install and run. Additionally, Xen has limited support for CD-ROM and network devices. The program is also available as a bare metal virtualization hypervisor on a Live CD. There are numerous third party extensions for managing Xen.

Audience: advanced users and professionals.

Pros: Full control and flexibility, very good performance, native kernel support.

Cons: UNIX-like systems only. Para-virtualization mode is buggy. Emphasis on the command line. A few command line utilities that can be confusing. Not easy to install and run. You must boot your own instance of the kernel.

A few words about virtualization programs

This review will be useful not only for novice users, but also for experts. The listed products cover a wide range of virtualization technologies at all levels. All solutions described are free for personal use. Choose what you want or need based on the available hardware, requirements for ease of setup and startup, as well as the availability of the required set of functions.

Typically, most people start learning virtualization with VMware Player or VirtualBox. Linux users may prefer KVM and perhaps Xen. Advanced users might want to take a look at ESXi.

So, if at startup, namely when starting the virtualization engine, then after rebooting the engine, go to the settings, they are next to the Close, Enlarge and Minimize buttons. So, in the Screen Section, set the DPI from high to low, if you set it to low, then don’t touch it. In the Engine section, select the graphics mode, DirectX or OpenGel, I personally set it to DirectX, and the most important thing is RAM, that is, we need to allocate a certain amount of computer memory for the program, personally I set it to 800 MB. (Default 768) Set RAM based on how many programs you have open, how powerful your machine is, and how much Memory you have in general (I checked, it’s better to set it to the maximum). And for CPU Cores, set the Maximum number of cores, I have 2, and I set it to 2, you can have 2 or more. Then click the Accept button and it will reboot itself, if not, reboot yourself.

can you tell me how the old version or how the old bluestax can be reinstalled after the computer format?? I was in a hurry and didn’t make a backup and now I’ve been looking for a way to open the old one for 3-5 days - since I have games there without an account. At the end it doesn’t load completely so that bluestax can open. some path or some mechanism is interfering - I don’t know what exactly, but somehow I was able to open it and there I was able to go to the main bluestax and when I wanted to rename the clones, errors occurred and now I can’t re-login.

2. Ruslan Krajnyukov
I reinstalled Windows and installed the licensed one. installed all the drivers, and just decided to make twins in taiji panda. and what happens I download this emulator, install it from the website. and it tells me that it is not possible to start the virtualization engine. what should I do in this situation??? Maybe splash around the laptop with a tambourine??? it is not weak, i3 processor, Gefors 940m 2 gig video card, 6 gig RAM. fresh Windows 10 pro. what can you tell me? where will you send your links??

3. AleX6X
Vasya, I can’t start it at all. In general, I will soon become a schizo with attempts to eliminate these problems.
Not a single emulator has worked for more than 2 months without crashes, glitches or application crashes.
What's Bluestaks, what's Nox, what's MEMU, etc.
I still can’t revive Nox...there have already been 3 reinstallations.
The system is extremely productive, especially for emulators. 2x Xeon E5620, 32 GB DDR3 ecc.
Quadro 4000 card.

4. Kasper
I tried a lot of things, and did as told and it finally worked. In the BIOS, during the first installation, the VR mode was not enabled - I barely set it up since it was an AM4 platform. I launched the program to check the support and whether it was enabled, it said that I had everything turned on, but the emulator did not start, I did it as the author says here and it worked The video is worth praising the author

5. Artyom Kozlovsky
I have such a problem when I start bluestacks, 3 small windows pop up where it says “The BlueStacks Android Host program has stopped working.” Without paying attention to these windows, BlueStacks starts the virtualization engine and almost at the very end the loading line stops and that’s it.

6. Chira Prime
I thought you would show me how to make this window seem IMPOSSIBLE TO START THE VIRTUALITY ENGINE. did not appear again and the bluestack worked normally. Well, this window is constantly opening. according to you, I will have to reboot the PC without stopping

7. Elena Derzhavina
I did everything strictly according to the instructions, installed Revo, cleaned the registry, checked folders, rebooted the computer, reinstalled this hat = zero results. After Revo, I also checked the registry with CCleaner.

8. Kasper
By the way, there are still problems with the plugin on Windows (openGL or DirectX), for example, I have problems with openGL, I went into settings and engine and there was a choice between openGL and DirectX, I chose DirectX and the whole problem disappeared

9. Alex Alexx
Use Nox and you won't have any problems. Proofit. Bluestacks was still crap.
The removal instructions still won't work. Don't torture yourself, bluestacks is just broken at the end.

Answer:
Nox also has its problems. some applications refuse to work normally on it.

BlueStacks is a program that creates a separate virtual reality for applications adapted for mobile devices like Android. This allows you to run them on your computer. When the virtualization engine does not start in BlueStacks, initialization of mobile applications on the computer is also impossible. There are many reasons for this - weak PC hardware, outdated drivers, high level of antivirus protection, unsuitable operating system.

Troubleshooting

Solutions:

It is often impossible to run the BlueStacks virtualization engine if your computer has a weak processor. Legacy models do not allow the hardware to perform virtualization processes. The problem exists for computers 10-12 years old; modern Intel and AMD support the ability to work with virtual machines.
Video cards manufactured before 2005 are not suitable for this type of work. They do not support the modern Open GL specification version 2.0 at a minimum. If you have a top-level video card and the problem persists, you need to update the graphics adapter drivers.
If the problem of the inability to launch BlueStacks on Windows 10 persists, then it makes sense to check the presence of similar programs on the computer - most often it is Windows VM or Oracle Virtualbox. You should delete them, clear the registry of residual files and reinstall BlueStacks. The problem may be a conflict between programs created on different virtualization engines. You can open the registry by pressing the Win + R keys, enter the regedit command and select the desired folder from the list.
Anti-virus protection often blocks the installation or correct launch of the emulator. You need to add BlueStacks to the antivirus whitelist or disable it. Before making this decision, it is better to check your computer for virus activity.
The application's RAM requirements are high—you need to make sure your computer has the required amount of unused memory. If part of the RAM is clogged with other applications, then it is better to end their activities through the task manager (simultaneously pressing the Ctrl+Alt+Delete keys).
If the problem persists, it helps to completely remove the emulator, including from the registry, and then reinstall it.

How to enable virtualization for BlueStacks?

Let's take a closer look at how to enable virtualization for BlueStacks using the BIOS. This will improve performance and make the emulator work faster.

First you need to find out whether your computer supports virtualization. The factor is determined by specially developed software - if the processor is Intel, then download the Intel Processor Identification Utility program. You can download it from this link from the official website. Install the utility, then run it, and the processor status will be displayed on the screen. If it says Intel (R) virtualization technology, then the computer supports the required technology.

If the processor is AMD, then use the AMD V detection Utility program. Install and run - the screen will read This system is compatible with Hyper-V. This means that virtualization is supported, and acceleration of hardware functionality in bluestacks is possible.

To enable virtualization via BIOS for Windows 10, 8.1, 8, you need to enter the UEFI BIOS.

How to do this for Windows 10: go to the system BIOS, then press start and click on settings. In the window that appears, click on Update and Security, then select Recovery at the bottom left. In the menu that appears, click on Advanced start-up and Restart Now. The background color will change to blue, there select Troubleshoot, then Advanced Options. Then click on UEFI Firmware Settings and click on Restart to be in UEFI (BIOS) after the reboot.

How to do this for 8.1, 8: go to the notification center (quick entry is performed by simultaneously pressing the Wmd and “C” keys), click on settings. Then click on the “Change PC settings” button. Then select “General” and “Restart now”. A reboot will occur and you will find yourself in the advanced launch system. There you need to click on “Troubleshooting”, in the menu that appears, click “Advanced settings”, select “UEFI settings” and restart the computer to end up in the BIOS.

Next we will talk about changes made to the system through the BIOS. The manual differs depending on the type of motherboard, chipset, processor and other components of the computer or laptop. To clarify the processes, please refer to the technical documentation for your device model. Below is a schematic principle of operation for a better understanding of the material, where the symbols “->” mean “further”.

Dell and Asus. When you start the computer, to enter the BIOS, press F2 -> Right arrow -> Virtualization (enable the effect) -> Enter -> Enabled (consent) -> Enter -> F10 -> Yes (save settings and exit) -> Enter. The computer will restart.

Acer. When you start the computer, to enter the BIOS, press F2 -> Right Arrow -> System Configuration -> Virtualization Technology -> Enter -> F10 -> Yes -> Enter. The system will reboot.

After such manipulations, the BlueStacks emulator will start.

Recently, users are increasingly hearing about such a concept as “virtualization”. It is believed that its use is cool and modern. But not every user clearly understands what virtualization is in general and in particular. Let's try to shed light on this issue and touch on server virtualization systems. Today, these technologies are cutting-edge because they have many advantages both in terms of security and administration.

What is virtualization?

Let's start with the simplest thing - the definition of the term that describes virtualization as such. Let us note right away that on the Internet you can find and download some manual on this issue, such as the “Server Virtualization for Dummies” reference book in PDF format. But when studying the material, an unprepared user may encounter a large number of incomprehensible definitions. Therefore, we will try to clarify the essence of the issue, so to speak, on the fingers.

First of all, when considering server virtualization technology, let's focus on the initial concept. What is virtualization? Following simple logic, it is not difficult to guess that this term describes the creation of a certain emulator (similarity) of some physical or software component. In other words, this is an interactive (virtual) model that does not exist in reality. However, there are some nuances here.

Main types of virtualization and technologies used

The fact is that in the concept of virtualization there are three main directions:

representation;
applications;
servers.

To understand, the simplest example would be the use of so-called ones that provide users with their own computing resources. The user program is executed exactly on and the user sees only the result. This approach makes it possible to reduce system requirements for the user terminal, the configuration of which is outdated and cannot cope with the given calculations.

For applications, such technologies are also used quite widely. For example, this could be virtualization of a 1C server. The essence of the process is that the program runs on one isolated server, and a large number of remote users gain access to it. The software package is updated from a single source, not to mention the highest level of security for the entire system.

Finally, it implies the creation of an interactive computer environment in which server virtualization completely replicates the real configuration of its “hardware” counterparts. What does this mean? Yes, that, by and large, on one computer you can create one or more additional ones that will work in real time, as if they existed in reality (server virtualization systems will be discussed in more detail a little later).

In this case, it does not matter at all what operating system will be installed on each such terminal. By and large, this does not have any effect on the main (host) OS and the virtual machine. This is similar to the interaction of computers with different operating systems on a local network, but in this case the virtual terminals may not be connected to each other.

Equipment selection

One of the clear and undeniable advantages of virtual servers is the reduction of material costs for creating a fully functional hardware and software structure. For example, there are two programs that require 128 MB of RAM for normal operation, but they cannot be installed on the same physical server. What to do in this case? You can purchase two separate servers of 128 MB each and install them separately, or you can buy one with 128 MB of RAM, create two virtual servers on it and install two applications on them.

If anyone has not yet understood, in the second case the use of RAM will be more rational, and material costs will be significantly lower than when purchasing two independent devices. But the matter does not stop there.

Security benefits

As a rule, the server structure itself implies the presence of several devices to perform certain tasks. In terms of security, system administrators install Active Directory domain controllers and Internet gateways on different servers rather than on the same server.

In the event of an external intervention attempt, the gateway is always the first to be attacked. If a domain controller is also installed on the server, then the likelihood of damage to AD databases is very high. In a situation with targeted actions, attackers can take possession of all this. And restoring data from a backup is quite a troublesome task, although it takes relatively little time.

If we approach this issue from the other side, we can note that server virtualization allows you to bypass installation restrictions, as well as quickly restore the desired configuration, because the backup is stored in the virtual machine itself. True, it is believed that server virtualization with Windows Server (Hyper-V) in this view looks unreliable.

In addition, the issue of licensing remains quite controversial. So, for example, for Windows Server 2008 Standard it is possible to run only one virtual machine, for Enterprise - four, and for Datacenter - a generally unlimited number (and even copies).

Administration issues

The advantages of this approach, not to mention the security system and cost reduction, even when virtualizing servers with Windows Server, should first of all be appreciated by system administrators who maintain these machines or local networks.

It becomes very common to create system backups. Usually, when creating a backup, third-party software is required, and reading from optical media or even from the Internet takes longer compared to the speed of the disk subsystem. Cloning the server itself can be done in just a couple of clicks, and then quickly deploy a working system even on “clean” hardware, after which it will work without failures.

In VMware vSphere, server virtualization allows you to create and save so-called snapshots of the virtual machine itself (snapshots), which are special images of its state at a certain point in time. They can be represented in a tree structure within the machine itself. Thus, restoring the functionality of the virtual machine is much easier. In this case, you can arbitrarily select restore points, rolling the state back and then forward (Windows systems can only dream of this).

Server virtualization programs

If we talk about software, there are a huge number of applications that can be used to create virtual machines. In the simplest case, native tools of Windows systems are used, with the help of which server virtualization can be performed (Hyper-V is a built-in component).

However, this technology also has some disadvantages, so many people prefer software packages like WMware, VirtualBox, QUEMI or even MS Virtual PC. Although such applications have different names, the principles of working with them are not particularly different (except in details and some nuances). With some versions of applications, virtualization of Linux servers can also be performed, but these systems will not be considered in detail, since most of our users still use Windows.

Server virtualization on Windows: the simplest solution

Since the release of the seventh version of Windows, a built-in component called Hyper-V has appeared, which makes it possible to create virtual machines using the system's own tools without using third-party software.

As in any other application of this level, in this package you can simulate the future by specifying the size of the hard drive, the amount of RAM, the presence of optical drives, the desired characteristics of the graphics or sound chip - in general, everything that is available in the hardware of a regular server terminal .

But here you need to pay attention to the inclusion of the module itself. Hyper-V server virtualization cannot be performed without first enabling this component in the Windows system itself.

In some cases, it may be necessary to activate support for the corresponding technology in the BIOS.

Use of third party software products

Nevertheless, even despite the means by which Windows servers can be virtualized, many experts consider this technology to be somewhat ineffective and even overly complicated. It is much easier to use a ready-made product, in which similar actions are performed based on automatic selection of parameters, and the virtual machine has greater capabilities and flexibility in management, configuration and use.

We are talking about using software products such as Oracle VirtualBox, VMware Workstation (VMware vSphere) and others. For example, a VMware virtualization server can be created in such a way that computer analogues made inside a virtual machine work separately (independently of each other). Such systems can be used in training processes, testing any software, etc.

By the way, it can be separately noted that when testing software in a virtual machine environment, you can even use programs infected with viruses that will only show their effect in the guest system. This will not affect the main (host) OS in any way.

As for the process of creating a computer inside a machine, in VMware vSphere server virtualization, as well as in Hyper-V, is based on the “Wizard”, however, if you compare this technology with Windows systems, the process itself looks somewhat simpler, since the program itself can offer some kind of templates or automatically calculate the necessary parameters of the future computer.

The main disadvantages of virtual servers

But, despite how many advantages server virtualization gives the same system administrator or end user, such programs also have some significant disadvantages.

Firstly, you can’t jump over your head. That is, the virtual machine will use the resources of the physical server (computer), and not in full, but in a strictly limited amount. Thus, for the virtual machine to work properly, the initial hardware configuration must be powerful enough. On the other hand, buying one powerful server will still be much cheaper than purchasing several with a lower configuration.

Secondly, although it is believed that several servers can be combined into a cluster, and if one of them fails you can “move” to another, this cannot be achieved in Hyper-V. And this looks like a clear disadvantage in terms of fault tolerance.

Thirdly, the issue of transferring resource-intensive DBMSs or systems like Mailbox Server, Exchange Server, etc. to the virtual space will be clearly controversial. In this case, obvious inhibition will be observed.

Fourthly, for the correct operation of such an infrastructure, you cannot use only virtual components. In particular, this applies to domain controllers - at least one of them must be “hardware” and initially accessible on the Internet.

Finally, fifthly, server virtualization is fraught with another danger: failure of the physical host and the host operating system will entail the automatic shutdown of all related components. This is the so-called single point of failure.

Summary

However, despite some disadvantages, such technologies clearly have more advantages. If you look at the question of why server virtualization is needed, there are several main aspects:

reducing the amount of hardware equipment;
reduction of heat generation and energy consumption;
reduction of material costs, including the purchase of equipment, payment for electricity, acquisition of licenses;
simplification of maintenance and administration;
the ability to “migrate” the OS and the servers themselves.

Actually, the advantages of using such technologies are much greater. While there may seem to be some serious downsides, by properly organizing the entire infrastructure and putting in place the necessary controls to keep things running smoothly, in most cases these situations can be avoided.

Finally, for many, the question of choosing software and practical implementation of virtualization remains open. But here it is better to turn to specialists for help, since in this case we were faced solely with the question of general familiarization with server virtualization and the feasibility of implementing the system as such.
