virtualization engine. What to do if the virtualization engine does not start in Bluestacks. Why you should use virtualization and virtual machines

So, if you have at startup, namely when you start the virtualization engine, then after restarting the engine, go to the settings, they are next to the Close, Zoom in and Minimize buttons. So, in the Screen Section, set the DPI from high to low, if you have it set 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, I personally set 800 MB. (Default 768) Set RAM according to how many programs you have open, how powerful your machine is, and how much Memory you have in general (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 2, you can have 2 or more. Then we press the Accept button and it will reboot itself, if not, reboot it yourself.

1. MrFMBALU
can you tell me how the old version or how the old bluestacks can be reinstalled after the computer format ?? I hurried and did not make a backup and now I have 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 does not load completely so that bluestacks opens. some way or some mechanism interferes - I don’t know exactly what, but somehow I was able to open it and there I was able to enter the main bluestack and when I wanted to rename the clones, errors occurred and now I can’t re-log in anyway.

2. Ruslan Krajnyukov
I reinstalled Windows, installed a 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 site. and it tells me that it is not possible to start the virtualization engine. what should I do in this situation??? Maybe with a tambourine splash around the laptop ??? it is not weak, i3 processor, vidyuha gefors 940m 2 gigabytes, 6 gigabytes of RAM. fresh windows 10 pro. what do you suggest? where do 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, crashes or application crashes.
What is Bluestaks, what is Nox, what is MEMU, etc.
Nox still can not be reanimated ... there have already been 3 reinstallations.
The system is extremely productive, especially for emulators. 2x Xeon E5620, 32GB DDR3 ecc.
quadro 4000 card.

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

5. Artyom Kozlovsky
I have such a problem when starting bluestacks, 3 small windows pop up where it says "The BlueStacks Android Host program has stopped working" ignoring these windows, BlueStacks starts the virtualization engine and almost at the very end the download line stops and that's it.

6. Chira Prime
I thought you would show how to make this window like IMPOSSIBLE TO START THE VIRTUALITY ENGINE. no longer appeared and the bluestack worked fine. this window is always open. according to you, I'll have to restart my 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 result. 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 to the settings and the engine and there was a choice between openGL and DirectX, I chose DirectX and the whole problem disappeared

9. Alex Alexx
Yuzat Nox and do not know the problems. Proofit. bluestacks has remained as shit as it was.
The delete statement still won't work. Don't torture yourself, the bluestacks just broke in the end.

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

Recently, users are increasingly hearing about such a thing as "virtualization". It is believed that its use is cool and modern. But far from 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 - the definition of a term that describes virtualization as such. We note right away that on the Internet you can find and download some kind of manual on this issue, such as the PDF-format "Server Virtualization for Dummies" reference book. 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 dwell on the initial concept. What is virtualization? Following simple logic, it is easy to guess that this term describes the creation of some kind of emulator (likeness) of some physical or software component. In other words, it 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 areas:

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 allows to reduce the 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 widely used. For example, it can be virtualization of a 1C server. The essence of the process is that the program is launched on one isolated server, and a large number of remote users get 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, the server virtualization in which completely repeats the real configuration of the "iron" brothers. What does this mean? Yes, what, 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).

At the same time, it does not matter at all which 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 in local network, but in this case, virtual terminals may not be connected to each other.

Equipment selection

One of the obvious and indisputable advantages of virtual servers is the reduction of material costs for the creation of a fully functional hardware and software structure. For example, there are two programs that require 128 MB to work properly. random access memory, but they cannot be installed on the same physical server. How to proceed 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 are significantly lower than when buying two independent devices. But the matter is not limited to this.

Security Benefits

As a rule, the server structure itself implies the presence of several devices to perform certain tasks. In a security plan, system administrators install domain controllers Active Directory and Internet gateways are not on one, but on different servers.

In the case of an attempted external intervention, the gateway is always the first to be attacked. If a domain controller is also installed on the server, then the probability of damage to the AD databases is very high. In a situation with targeted actions, attackers can take over all this. Yes, and restoring data from a backup is a rather troublesome business, although it takes relatively little time.

If you approach this issue from the other side, it can be noted 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, as it is believed, server virtualization with Windows Server(Hyper-V) looks unreliable in this view.

In addition, the issue of licensing remains quite controversial. So, for example, for Windows Server 2008 Standard, only one virtual machine can be launched, for Enterprise - four, and for Datacenter - an unlimited number (even copies).

Administration Issues

The benefits of this approach, not to mention the security and cost savings, even when servers are virtualized with Windows Server, should primarily be appreciated by system administrators who maintain these machines or local networks.

Very often becomes the creation backups systems. Usually, when creating a backup, third-party software is required, and reading from optical media or even from the Network takes longer than 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 the 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 performance of a virtual machine is much easier. At the same time, you can arbitrarily choose restore points, rolling back the state back and then forward (Windows systems can only dream of this).

Server virtualization programs

If we talk about software, here you can use a huge number of applications 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 drawbacks, so many prefer software packages like WMware, VirtualBox, QUEMI, or even MS Virtual PC. Although the names of such applications differ, the principles of working with them do not differ much (except in details and some nuances). With some versions of applications, virtualization can also be performed. Linux servers, 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 Windows versions a built-in component called Hyper-V appeared in it, which made it possible to create virtual machines using the system's own means 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 hard drive, the amount of RAM, the presence of optical drives, the desired characteristics of a graphic or sound chip - in general, everything that is in the "hardware" of a conventional 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 feature on the Windows system itself.

In some cases, it may also be necessary to enable the activation of support for the corresponding technology in the BIOS.

Use of third party software products

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

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

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

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

The main disadvantages of virtual servers

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

First, 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 buying several with a lower configuration.

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

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

Fourth, for the correct operation of such an infrastructure, it is impossible to use exclusively virtual components. In particular, this applies to domain controllers - at least one of them must be "hardware" and initially available on the Web.

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

Summary

Nevertheless, despite some disadvantages, the advantages of such technologies are clearly greater. If you look at the question of why server virtualization is needed, here are several main aspects:

reduction in the amount of "iron" 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 possibility of "migration" of the OS and the servers themselves.

Actually, the advantages of using such technologies are much greater. While it may seem that there are some serious drawbacks, with the right organization of the entire infrastructure and the implementation of the necessary controls for smooth operation, in most cases, such 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 only with a question of general familiarization with server virtualization and the feasibility of implementing the system as such.

Bluestacks is an Android emulator for Windows. A program that is used primarily for playing mobile applications on a computer. However, various failures can occur periodically in it, especially with the virtualization engine.

Causes

Hyper-V enabled

Hyper-V is virtual machine, which is built into Windows 10 and modern server operating systems. Sometimes enabling or disabling a technology can allow the emulator to run smoothly. To check this component, you need to open "Windows Components". This is done as follows:

Problem Source: Antivirus

Sometimes a running antivirus can have an effect. At startup you need turn off screens antivirus and see the result. If the problem is solved - an exception is added for Bluestacks. If not, the problem is not related to the antivirus.

Reinstallation

The last option to fix the error with the virtualization engine would be app reinstallation. For this it completely removed, downloaded (the best option from the official site) and installed again. It is important to restart your computer after installation.

Virtualization allows you to encapsulate the internal device operating systems or parts thereof within virtual hardware and software. In other words, to 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 for Windows 7, Linux and Mac OS X do. Virtualization also allows you to simulate devices that are not even on your computer.

Note A: 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 usually a regular operating system application or service that allows you to create hosts. A host is any physical machine (computer). Inside the virtualization software, the operating system runs in a similar or identical real 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 provided features for guests. There is the usual 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 goes through an intermediate layer. And there is also system-level virtualization, when each guest system is loaded 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 distribution 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 an abstraction layer 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 security 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. Continuing on the subject of safety...

Why use virtualization and virtual machines?

If security is your top priority 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, you should not assume that virtualization is mainly used for security. Its initial goals are: testing, cost reduction, flexibility, old product support, and education. Increasing the level of security is just a nice bonus, which has a lot of its own 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 do you need 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 different operating systems may be required. Virtualization does not imply any one solution that will run wherever needed. Virtual machines need to be selected for the system (Windows, Linux, Mac) and for 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 CPU 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 the use of resources on the real system in order for the virtual machine to function properly. Of course, unless you are trying to run Windows XP with 256 MB of memory. However, if you have 16 GB of RAM, then you can run far more than one guest system without feeling any lack of resources.

Pros: Easy to install and use.

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

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

VirtualBox is another cross-platform virtual machine software 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 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. In addition, there is portable version virtual box. However, there are also disadvantages. You cannot take screenshots of guest systems. Disk management is somewhat confusing.

Audience: Beginners and experienced users.

Pros: Easy to install and use, lots of features.

Cons: No screenshot support, difficult to import existing machines, unintuitive disk management.

VMware ESXi hypervisor for creating virtual machines

ESXi is a bare-metal hypervisor with cut functionality compared to ESX. The application requires a host and can be controlled from the console (the console is disabled by default, but you can enable it manually). You will not be able to take screenshots or capture video from the screen of your virtual machines. Transferring and cloning guest systems is done only manually. But, on the other hand you get memory sharing for better use of RAM, powerful control 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 only supports virtualization for UNIX-like operating systems (Linux). The application can be run on any hardware or in emulation mode, but without processor extensions, performance will be terrible. KVM is designed to be used through the console. But, it has a decent management interface that allows you to start and stop virtual machines, take screenshots, and more. The interface is known as Virtual Machine Manager (VMM) and is also used to manage Xen virtual machines (see below). Support for local and remote control. There is a known conflict with VirtualBox, but it can be resolved relatively easily

Audience: advanced users and professionals.

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

Cons: Only UNIX-like systems. Requires virtualization hardware 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 be loaded in its 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 kernel release upstream. Xen can run in hardware-assisted or para-virtualization mode. However, for para-virtualization, Xen is extremely problematic to install and run. In addition, Xen has limited support for cd-rom and network devices. It 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: Only UNIX-like systems. Para-virtualization mode is buggy. Emphasis on the command line. Multiple Utilities command line which can be misleading. Not easy to install and run. You need to load your own kernel instance.

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 hardware you have, your requirements for ease of setup and launch, and the feature set you need.

As a rule, most people start learning about virtualization with VMware Player or VirtualBox. Linux users may prefer KVM and possibly Xen. Experienced users might want to take a look at ESXi.

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

Troubleshooting

Solution options:

It is often impossible to run the BlueStacks virtualization engine with a weak computer 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 released before 2005 are not suitable for this kind of work. They do not support the modern Open GL specification version 2.0 at least. If the video card is top-level, but the problem remains, you need to update the graphics adapter drivers.
If the problem of the inability to launch BlueStacks persists on Windows 10, then it makes sense to check for similar programs on the computer - more often it is Windows VM or Oracle Virtualbox. You should delete them, clean the registry of residual files and reinstall BlueStacks. The problem may be in the conflict of 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.
Antivirus protection often blocks the installation or correct launch of the emulator. You need to whitelist BlueStacks antivirus or disable it. Before this decision, it is better to check the computer for virus activity.
The requirements for the amount of RAM by the application are high - you need to make sure that the computer has the required amount of unallocated memory. If part of the RAM is clogged with work by other applications, then it is better to end their activities through the task manager (simultaneous pressing of the Ctrl + Alt + Delete keys).
If the problem persists, complete removal of the emulator, including from the registry, and subsequent reinstallation helps.

How to enable virtualization for BlueStacks?

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

First you need to learn about the possibility of virtualization support by the computer. Determines the factor specially designed software- if Intel processor then download the Intel Processor Identification Utility. You can download this link from the official site. Install the utility, then run it, and the processor status will be displayed on the screen. If Intel (R) virtualization technology is written, then the computer supports the required technology.

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

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

How to do it for Windows 10: go into the BIOS of the system, 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 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 the settings. Then click on the "Change PC settings" button. Then select "Basic" and "Restart now". A reboot will occur and you will be in the advanced launch system. There you need to click on "Troubleshoot", in the menu that appears, click "Advanced settings", select "UEFI settings" and restart the computer to be in the BIOS.

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

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 starting 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.
