A huge number of programs appearing every day make downloading and installing unknown software on a computer more and more dangerous for the system and important files on the computer. In addition, many programs that have functions necessary for the work of programmers, artists and other PC users are available only for a small number of operating systems. If previously you had to take a lot of risks by downloading a suspicious file from the Internet, or reinstalling the system just for the sake of one necessary program, now there is an OS for this, such as a virtual machine.

What is a virtual machine

Virtual machine- a special program that is installed on the user’s native operating system and, when launched, begins to emulate, that is, reproduce, the functions of any other operating system specified in the settings. The main convenience of such programs is the absence of the need to switch between operating systems and access to all functions of the system being reproduced. In addition, all actions performed inside the virtual machine will not affect the operation of the main system, which prevents possible computer failures.

At the moment, virtual machine developers have created programs that allow them to emulate any operating system, from early versions of Windows to Ubuntu, OS X and lesser-known axes, and also work with ready-made servers, for example, Bitrix virtual machine.

There is another, narrower understanding of the term “virtual machine”, which is common among musicians - virtual drum machine, which plays the sounds of a drum kit. This program allows you to record parts of drum instruments without using a live setup, but in special recording programs or by “revitalizing” a pre-recorded midi track, placing recorded samples of each beat under the electronic sound.

What is a virtual machine for?

The range of actions that can be performed using a virtual machine is actually very large.

The simplest thing you can do with it is to use programs that are not available for the user’s operating system or even for the PC in general. For example, an emulator of the Android operating system is essentially also a virtual machine with which people run applications or games.

In addition, virtual machines are often used by programmers to test written programs. For example, to check how correctly a written algorithm works in different versions of Windows. The same applies to developers of applications for iOS and Android, who check the functionality of their developments inside emulators. For this purpose, there is a virtual machine on a flash drive, so that you can always check the functionality of the written code.

The machines are also used by less advanced users for such checks. The fact is that when emulating related operating systems, the machine can reproduce all the information contained on the computer. Therefore, if a user has to download a file from the Internet that may contain viruses, he should first check it on a virtual machine. If it plays normally on it, then you can safely open it on your native OS.

In addition, they help in corporate work, say, Bitrix virtual machines.

If we talk about virtual drum machines, they are used to record drum parts with high quality when there is a lack of funds, for example, to rent a studio. Of all the instruments, drums are the most sensitive to recording, and it is they that you spend the most time on. In addition, the drummer may not have sufficient skill to play them smoothly, which significantly increases the cost of rent. In such a situation, the best way out would be to record the part in the program and then play it back.

What are virtual machines?

Virtual machine for Windows 10

Especially for advanced users familiar with the concept of a “virtual machine,” Microsoft made built-in emulation of other operating systems - . Initially, its functionality is blocked, but its components are easily enabled through the Control Panel.

Go to the Control Panel and go to the subsection " Programs and components" There in the window " Turning components on or off» Check the name of the Hyper-V service. After this, the virtual machine will be installed on the PC, and in the future you can launch it through the menu “ Start».

Key Benefits of Hyper-V:

built into the system, no need to download or search for anything;
has full functionality for emulating different versions of Windows, for example, 98 and other operating systems;
supports Windows versions of different bit depths;
simple and intuitive interface.

In general, thanks to the presence of Hyper-V on Windows 10, users no longer need other similar programs. Although the utility does not require any special skills to configure, you can read more about it in the related article.

Virtual machine for Windows 7

The most popular virtual machine for Windows 7 users is Windows Virtual PC. Initially, its main functionality was intended to emulate Windows XP, so that developers could comfortably transfer programs developed for this OS to the new seven, which was just being released at that time. Subsequently, its capabilities expanded, and now Virtual PC is a separate platform that is capable of reproducing almost all existing operating systems.

Like Hyper-V, this service is built into the system natively. In order to install it, you need to go to " Start" and submenu " Programs" There you need to find a line with the name of the program and click on it. A window will open in which you can freely create, delete and perform other manipulations with the operating system emulator.

Virtual machines for Mac and other OS

In addition to the virtual machines built into Windows 7 and 10, third-party developers have created many other independent utilities that have approximately the same capabilities, but differ in details. The most popular of them is Oracle VirtualBox, which will be discussed in this part of the article.

This virtual machine can emulate all currently existing operating systems, and is also available for the most popular operating systems at the moment - Windows, OS X, Linux and Solaris. You can download it from the developer’s website, having previously selected which system you need it for.

This Oracle program differs from its other analogues in its wide functionality, which includes support for USB ports and their launch from an emulated machine, the ability to save the system state for instant rollback in case a critical error occurs. In fact, from the huge list of all supported features, we can conclude that by downloading Oracle VirtualBox, you can comfortably work on any operating system without any restrictions at all.

For most users, VirtualBox is a very good choice due to its practicality, reliability and functionality.

Once the application distribution is on your computer, double-click on it. This will launch the installer. Here you will need to select which features, in addition to the Oracle machine itself, are installed with it. The list includes: the possibility of internal programming in Python, configured support for the Internet, as well as integration of USB ports. After this, just follow the instructions in the installation file until the installation of Oracle VirtualBox is completed.

Virtual drum machines

Virtual drum machines are present in the form of additional plugins that are installed and launched through a program for recording or writing music - FL Studio, Ableton, Cubase and others. The most popular drum machine emulators - EZ Drummer And Addictive Drums. Large libraries of samples for every taste, recorded by famous drummers, are freely available to them.

Creating your own virtual machine

In addition, there is also a company VMWare, which also offers users programs to create their own virtual machines. The most famous of them is called Workstation and is distributed on a paid basis. However, there are a lot of resources that offer free use of this virtual machine, both for Windows, Mac, and Ubuntu. It is worth noting that the company offers a lot of additional utilities that expand the capabilities of the basic program, adding desktop management functions, broadcasting and much more. Let's look at why this virtual machine is needed.

Workstation allows you to create virtual machines that will be managed from a single center. For the most part, this tool is of interest to large companies that need to configure the same functionality of devices on a large number of computers.

One of the most important features that the VMWare virtual machine has, the so-called vSphere, which allows you not only to create and configure a virtual machine, but also to implement an entire infrastructure of such devices connected to each other. And if you have to choose, then this functionality will be very useful for large companies whose employees need to exchange data and information with each other.

All functionality of programs developed by VMWare is based not on the single use of a virtual machine, but on the formation of a network of them and a single place from where this network is controlled.

Virtualization 1C-Bitrix

Another program created for comfortable work with 1C-Bitrix products - Bitrix virtual machine, this time from domestic developers, which can also work with any PHP applications. Essentially, this program is an emulation of a website server that contains all settings for comfortable work. The finished machine can be opened in VMWare Player or other applications from this developer (there are also versions for VirtualBox and HyperV).

The program allows you to save time and get started immediately after the main platform is ready for use. In this case, the Bitrix virtual machine is installed directly into the main emulation system, integrating into its functionality and operation, which allows you to begin interacting with 1C projects immediately after installation and launch.

Which virtual machine to choose

There is no clear comparison anymore. It all depends on the user and his needs. To emulate games and check third-party software, the usual Hyper-V services and the like, built into the operating system itself, are quite sufficient. A well-tested, reliable and free option is VirtualBox. For organizations, the best virtual machines are definitely VMWare products or the Bitrix virtual machine, since they simplify doing business and interacting with employees.

Video on the topic

One operating system - virtual - inside another operating system, but a real one - this is an ideal find for those who like to test third-party software as well as different versions and builds of operating systems.

It's safe, it's interesting, moreover, it's even useful for development. The VirtualBox program is perhaps the only widely known representative of software that provides the mentioned capabilities.

It is free, simple and easy to use even for novice users. How to install a virtual Windows operating system using VirtualBox? We will consider this question below.

Step 1. Create a virtual computer

There are unlikely to be any problems with downloading and installing VirtualBox; it can be freely downloaded from developer's official website, and it is installed as standard.

The launched program will open with a welcome window, where you need to click the “Create” command.

The window that appears will give you a choice of operating systems supported by the program. We select the required version, set a name for the virtual computer. Click "Forward".

We indicate what system we are creating:

Correct operation of Windows XP will be ensured by 512 MB of RAM, but for Windows 7 it is better to allocate 800-900 MB.

You cannot enter the red section of the scale, thereby giving the virtual computer more than half the hardware potential of the physical computer. Click "Forward".

In the next hard drive selection window, select the option to create a new hard drive.

In the next window, it is better for beginners to choose a storage format - fixed disk, since it works a little faster than dynamic. Click "Forward".

This figure will also be taken from the memory of the physical hard drive, so it is necessary to select the optimal amount, which will be enough for the purposes of operating a virtual computer, and this will not be to the detriment of physical memory.

For Windows XP you can allocate 5 GB, and for Windows 7 – about 15 GB. Here, using the browse button visible at the end of the first line, select the directory of the physical computer where the virtual hard drive will be placed.

It is better to choose a location on a non-system drive. The “Create” command will start the process of creating a virtual computer hard disk, after which you can admire the parameters of the newly created virtual computer.

Step 2. Install the operating system on the virtual computer

The virtual computer has been created and the operating system can be installed on it. Click the “Run” command.

We select either the operating system boot disk located in the physical drive or the disk image. You can set the path to the disk image using the browse button at the end of the line. Click “Continue”.

VirtualBox (Russian: Virtual Box) is a virtual machine from Oracle Corporation. A free program designed for virtualizing operating systems Windows, macOS, Linux, FreeBSD, Solaris/OpenSolaris, other platforms are supported.

Benefits of a virtual machine

Using a virtual machine (VM) on a home PC, first of all, will allow you to simultaneously run several operating systems (guest OS).

For example, one of the editions of the Microsoft Windows operating system (host OS) is currently installed on your computer or laptop. Installing a virtual machine, in this case VirtualBox, allows you to use any other systems (guests) in the host OS environment, including macOS, Linux, Android, Windows, and so on; there can be a lot of options here.

Some features and capabilities of VirtualBox

Support for VMDK () and VHD (Microsoft Virtual PC) hard disk images;

What's new in version: List of changes

Sometimes, for different purposes, the user needs to use several systems at once. There is an option, of course, to use several computers at once or install several systems on one, but this is inconvenient and impractical. In this situation, there is one solution that has long been used among programmers and developers - installing a virtual machine for Windows. In this article you will learn how to install a virtual machine under Windows 7, 8, 10.

Which virtual machine should I choose?

You may not believe it, but there is quite a large selection of virtual machines. Each of them has its own specific functionality and features. Please note that it will not be possible to install a powerful virtual machine on a weak computer, and in general, weak computers are difficult to tolerate programs of this kind. If you have less than 2 GB of RAM on your PC and less than 100 GB of free space on your hard drive, we do not recommend installing a virtual machine. First increase the memory, and only then use it to the maximum.

For everyday tasks and regular use, we recommend using the program VMware Workstation, which is a whole range of applications for working with a virtual OS. You can figure it out even if you have never used such programs. It is easy to use, does not consume a lot of RAM and includes the integration of a virtual system into the main one, which allows you to use them in parallel in the same work environment. We suggest you carefully consider the VMware installation process.

We tested version 11 of this software, it supports everything that both a novice and an experienced user will need.

VMware Workstation installation process

This completes the installation process, now we move on to how to install the OS on a virtual machine for Windows. Please note that any OS that has an installation file is suitable for installation. Let's look at an example of installing Windows 7 Ultimate on VMware Workstation.

How to install an operating system on VMware Workstation

First, you need to download the OS installation file to your computer. You can use the search and find this file, or you can simply ask someone for an installation disk (homemade) and download from there.

After downloading Windows to your computer, we will begin the OS installation process.

We create a new virtual machine. To do this, go to the menu "File - New Virtual Machine";
The negotiation of the parameters of the future VM will begin. In the first window, you will be asked how you want to install it. We suggest you choose "Selective" configuration type and click "Further";
In the next window we also click "Further";
In the next window you will be asked to select the source for installation "guest" OS. If you took the installation disk, specify the drive, and if you downloaded it from the Internet, specify the path to the file using the button "Review". After that click "Further";
Now you need to provide your product key and OS user information. We only recommend choosing "Windows 7 Ultimate", and skip the rest;
Enter a name for the new virtual machine or leave the old one, and then define the parameters. Let's start with the type of firmware - leave the BIOS, and the number of processors - 1/4 of those available to you. We have 4, so we set it to 1, but with two cores. With RAM it’s about the same, but 1/3 of the total available memory. We have 4, but about 3 are available, so we set it to 1 GB;
Now let's figure out the Internet for the virtual machine. We leave everything as is further, where they ask about the controller, the type of virtual disk;
We recommend put 20-30 GB for the virtual OS hard disk, and then specify the path where the virtual OS file will be stored;
Check all the installed parameters and the OS installation will begin;
Next, the standard OS installation will occur. Just follow the progress and, if necessary, enter user information;
After successful installation, start the virtual machine and check its functionality;
After the virtual machine has been successfully launched, the system will start. Wait for completion;
After downloading you will be taken to "Desktop" virtual machines and you can start working;
To manage a virtual machine for Windows, you need to click on the desktop;
When work in the guest OS is completed, you need to turn off the virtual machine in the same way as when using a permanent system - “Start - “Shut down”, otherwise you may “break” it. Good luck using VM for Windows 7, 8, 10!

The topic of virtualization is very popular. There are discussions on this issue on the Internet, articles are written and books are published. This problem has been included in computer courses at universities, and is increasingly being developed in practical applications. What is a virtual machine (VM), and which virtual machine for Windows 7 is better to prefer than others to solve specific user tasks.

A virtual machine is a program that simulates the behavior of some other machine on that machine and allows one system to run software written for another system. The depth of simulation can be different, so there is a whole classification of virtual machines that takes into account the level of detail of the simulation.

The VM can be programmed in such a way that it repeats in detail the behavior of the processor and bus of the emulated system. This is the deepest level of software emulation.
You can only emulate the operating system API of the simulated computer.
Or you can simply rewrite the entire package of the source software system for the target system. With this approach, the architectural features of the simulated object are not taken into account at all.

Another question that is important in the context of discussing VMs for Windows 7: do we want to run the “seven” on another OS or, conversely, is our task to recreate the operation of another OS on the “seven”? We will consider all these nuances in our short note.

What virtual machines are there?

If you look at Wikipedia, you can find pages there with a fairly detailed explanation of the operating principle of VMs and their programming technologies. These pages are: https://ru.wikipedia.org/wiki/Emulation, https://ru.wikipedia.org/wiki/Virtualization, https://ru.wikipedia.org/wiki/Virtual machine/. On these same pages you can get a first idea of the diverse applications of such programs in practice. The average home computer user may benefit from such VM qualities that will simplify his daily work or provide a non-standard gaming environment. The educational aspect of VM is also important, as it increases the general cultural level of the computer owner. Here is a list of interesting features:

Creating an environment for running retro games and retro programs. Sometimes a comparison of ultra-modern three-dimensional toys and games of the 80s and 90s of the last century allows us to take a fresh look at the results of progress in this direction. Another example: when teaching schoolchildren programming, packages like “LogoMira” and the like are often used. You can do it differently - run the emulator of the Soviet "Agat" and get the same Logo in a simple and controlled environment of an 8-bit household computer.
The need to regularly switch from Windows to Linux is not uncommon today. Instead of installing both systems on your PC, you can use virtualization.
Try installing a simulator of the first personal machine, the Xerox Alto, on your computer, and your ideas about how far computer interfaces have come will change. Or run the chip-08 simulator.
