What are virtual machines used for? Virtual machine: what it is, what is it for

Be sure to install the VirtualBox Guest OS or VMware Tools add-ons

After installing the guest operating system in the virtual machine, the first thing to do is to install the virtual machine software - "Guest OS Add-ons for VirtualBox" or VMware Tools for VMware. "These packages include special drivers to help your guest operating system work faster on using the hardware of your main machine.

Installing the package is simple - in VirtualBox, after booting up the guest operating system, click the Devices menu button and select "Install Guest Additions". If you are using VMware, select “Install VMware Tools” from the Virtual Machine menu. Follow the instructions on the screen to complete the installation - if you are using Windows as your guest operating system, this will be the same as installing any other application.

Make sure you have the latest Guest Additions - if you see a notification that an update is available for Guest Additions or VMware Tools, you must install it.

Creating a fixed size disks on initial setup

When creating a virtual machine, you can create two different types of virtual disks. By default, the program usually suggests using dynamically allocated disks that grow along with the space occupied by the guest OS.

For example, if you create a new VM with a dynamically allocated disk with a maximum size of 30 GB, it will not take up to 30 GB of hard disk space right away. After installing the operating system and programs, the disk may only take up to 10 GB. As files are added to the virtual disk, it will expand to a maximum size of 30 GB.

This can be convenient - each virtual machine will not take up unreasonable amount of space on your hard disk. However, this is slower than creating a fixed disk size (a disk with pre-allocated space). When you create a fixed size disk, the entire 30 GB will be used immediately on your computer.

There is a trade-off here - a fixed disk size takes up more hard disk space, but works faster with a virtual hard disk. You will also get rid of file fragmentation - space will be occupied by a large block instead of adding smaller chunks all over the disk.

Exclude the virtual machines directory in your antivirus

Your antivirus can scan virtual machine files as they are accessed, slowing performance. Antivirus will not be able to detect a virus inside a virtual machine running on your guest operating system, so this check only does harm.

To speed up the process, you can add your virtual machine directory to the antivirus author's exclusion list. Once it's on the list, your antivirus will ignore all files in that directory.

Allocate more memory

Virtual machines love a lot of virtual memory. Microsoft recommends 2GB RAM for 64-bit Windows 7, and this recommendation applies to Windows 7 x32 as well when running in a virtual machine. If you are running large applications in a virtual machine, you can allocate more than 2GB of RAM.

You can allocate more RAM in the settings dialog of your virtual machine (the virtual machine must be turned off to do this). If your computer does not have enough memory to comfortably work with a virtual machine, you may notice a very large decrease in computer performance when using the paging file on your hard disk.

Allocate more processors

If you have a computer with multiple processors or cores, you can allocate additional processors for your virtual machine from the VM settings window. A VM with a dual-core (or quad-core) processor will be more responsive.

If you are going to install an OS of the MS-Windows family and in the future, so that you can use more kernels during installation, specify 2 kernels in order to install the correct HAL, after installation you can turn off the machine and set 1 kernel by default for everyday use. But for the future, you can always add kernels without uninstalling the OS. Linux VM can dynamically detect any number of cores when the OS boots.

Adjust video settings

Fine-tuning your video settings and allocating more video memory will also help improve the speed of your virtual machine. For example, enabling 2D acceleration in VirtualBox improves video playback in virtual machines, enabling 3D acceleration will allow you to use some 3D applications.

By and large, you need to minimize the use of 3D for example Windows 7 - by disabling Aero.

Make sure Intel VT-x or AMD-V features are enabled

Intel VT-x and AMD-V are special processor extensions that improve virtualization speed. Newer Intel and AMD processors usually include these features. However, some computers do not automatically enable VT-x or AMD-V - you will have to enable this setting in your computer's BIOS.

To determine if your Intel processor supports the Intel VT extension, use the utilities that display the system information. If your processor supports this feature, but the option is not available in your virtual machine, you must enable this feature in your computer's BIOS. This option is usually enabled by default on motherboards with AMD processors.

Place the virtual machine files on a different disk

Disk performance can limit the speed of your virtual machine. Placing virtual machine files on a separate physical disk or not on the system disk can improve performance. Your virtual machine and system will not be able to concurrently read and write from the same disk.

However, you do not have to start the virtual machine from an external disk (USB) - it will be much slower.

Dedicating additional processors is rarely a good idea. Use 1 CPU for desktop OS.
Try not to use graphical hypervisors for server operating systems.
Do not allocate more cores to a running VM than there are on your computer.

Let's take a closer look at what virtual machines for Windows are and what they are for. Learn all about the best OS simulators and how to get started using them.

A virtual machine (VM) is a computer application that allows a user to create an imitation of an operating system. An OS image is installed on the machine for use inside the existing system. Very convenient, isn't it? But there are also pitfalls. Read what you will encounter during installation and which virtual machine for Windows versions 7.8 and 10 is better to choose.

Why do we need PC virtual machines?

In most cases, VMs are used to test software in. To work with several operating systems, you need only one computer, which significantly speeds up the work.

Several virtual machines can run on one computer at the same time. Their number depends on the available RAM and the space on the children's disk, since a virtual OS consumes exactly the same memory resource as a regular copy installed on a computer.

With the help of virtual machines, you can work with programs, functions that are not available in the main OS. Also, it is possible to create backup copies of VMs, with their subsequent movement and use on other computers.

Viruses, errors and other failures of the virtual OS do not affect the operation of the main system. After the machine is closed, the additional OS stops working and the RAM is freed.

During the operation of the VM, the device may slow down, because the increased consumption of storage resources leads to an increase in the processing time of requests.

Reasons for installing VM:

You want to familiarize yourself with the work of other operating systems without fully installing them. If there is a need to replace the existing OS, first use the virtual simulator to test other software options. This will save you from possible bugs and incompatibilities with the hardware;
You are a developer and want to create a complex system for testing the applications you create.

Virtualbox

VirtualBox is a virtual machine for Windows 7,8,10. The virtualization environment is distributed free of charge and can be installed both for working with operating systems and for deploying network infrastructure and hosting sites.

VirtualBox main window:

The main feature of this virtual machine is cross-platform. It works fine on all versions of Windows. Also, from the developer's site you can download installers for Mac OS, Debian. In the virtualization environment itself, you can install any desktop OS.

With VirtualBox, you can familiarize yourself with the functionality of the OS or test the program in safe mode without harming the main system. Users often prefer to install old games on virtual machines that are incompatible with modern operating systems.

After the simulator is finished, all data and changes will be saved. The next time you turn it on, you will be returned to your desktop and can continue to perform tasks.

Advantages and disadvantages

VirtualBox advantages:

Free distribution. 90% of similar software is paid, while VirtualBox is completely free. The functions and capabilities of the program are not limited to the developer;
The ability to create screenshots - screenshots of the virtual system. The resulting image will only display the secondary OS window. Taking screenshots with the main OS degrades the resolution and also hijacks your regular desktop;
Creation of an exact copy of an existing virtual machine;
Ability to drag folders, shortcuts and other objects inside the simulator;
Unified file system - from a virtual machine, you can access directories that are stored on a PC, and vice versa;
Simultaneous work with several machines.

Also, a distinctive feature of the new VirtualBox 4 is a convenient virtualization management system and an intuitive workspace of the program. Also, in the new assembly, the ability to capture video from the screen of an additional OS is available.

VirtualBox supports working with USB drives connected to the computer.

Disadvantages of the program:

Slow down your computer. Even if your PC has good technical specifications, sufficient RAM and storage space, when using a virtual machine, you will experience slower performance of all functions. If during the creation of a VM you have allocated too much memory, the computer will freeze or shut down;
Insufficient video memory. If you need to achieve the best possible image quality, this will be difficult with VirtualBox. The program allows you to configure the settings for using the video card only at a basic level.

How to install

To install the VirtualBox program, download the installer from the official site of the developer - the Oracle company. The installation process is standard and does not require additional settings:

Run the EXE file;
Select the Hard disk where the root folder with the program will be located;
Wait for the installation to complete. If necessary, the user can view the statistics of hard disk usage during the installation process.

In the field "Custom Setup" there is an option to disable support for USB, network services. This helps to reduce the total size of the application.

Video tutorial on how to install two OSes using VirtualBox

After installing the program, you can start creating your first virtual machine. Click on the "Create" button in the upper left corner of the window. The VM settings tab will open:

In the setup wizard window, select the type of virtual OS (Windows, Linux, Debian, MacOS) and its version. Specify a name for the simulator to be created and click on the "Next" button.

Then, the program will provide you with the opportunity to independently specify the size of the RAM that will be allocated for the additional OS. For newbie users, we advise you to set the value that is indicated in the "Recommended size of main memory" field.

The size of the RAM for the VM should be determined depending on the specifications of your PC. If you have 4 GB of RAM available on your computer, 512 MB-1 GB will be sufficient for the simulator to function properly.

Next, the program will ask you to select an OS image in the file system (which corresponds to the previously specified family and version). After completing the configuration, a window will appear with a brief listing of all parameters. Click on Finish.

After the installation of virtual Windows is complete, an icon for starting the OS will appear in the main window of VirtualBox. Click on it and wait for the desktop to load. Install the drivers if necessary.

To automatically update drivers, open the Devices tab in the virtual machine toolbar. Then click on the desired media type and in the new window follow the instructions to get the new software.

Ready. You can now start working with the virtual operating system. To exit the program, first shut down the OS and then close VirtualBox.

VMware

VMWare Workstation is the best virtual machine for Windows 10. The developer positions the program as a convenient platform for creating. Compared to other popular counterparts, VMWare supports more functions for customizing the virtual machine and allows you to synchronize the simulator with software development tools.

This virtualization environment is popular among programmers, web designers and other professionals who often have to test the work of their projects for cross-platform.

Advantages and disadvantages

Among the advantages of VMWare are:

Convenient toolbar;
Synchronization with development tools from Microsoft, in particular the .NET platform and the Visual Studio software environment;
Safety system. Built-in VMWare tools provide a high level of protection for your files in the secondary OS. The simulator can detect attempts by malicious activity to eliminate them;
Operation of encryption services for the created virtual machines.

Disadvantages of the application:

Paid distribution. The user can download a free trial version of the utility, but to get the full version of the application with all available functions, you will need to pay for an annual or monthly subscription;
Not suitable for beginners. If you have not used operating system simulators before, we recommend starting with the simpler options. For example, VirtualBox and the standard Windows Hyper V. VMWare is suitable for advanced users who prefer to manually configure the system.

How to install

You can download a virtual machine for Windows from the official developer site VMWare.com.

It is recommended that you turn off Windows Defender or another running antivirus during the installation process. This is only necessary for the correct installation of all files and encryption algorithms used by the program for virtual machines. No harm will be done to your main OS as the product is downloaded from an official source.

Review of functionality and first setting of the program

To create the first virtual machine in VMWare, you need to download the OS distribution kit that you want to use in the emulator on your computer. Then open the window of the installed application and click on the field "Create a new virtual machine"

Note! The user can create a group of virtual machines instead of several simulators. This allows you to reduce the resource of the consumed RAM and speed up the operation of the computer and the OS simulator.

In the window of the VM setup wizard, specify the path to the operating system image (this can be a file in the computer's memory or a boot disk). Also, it is possible to configure a virtual machine without installing an OS (you can install it later).

In the window that appears, specify the OS name, username and password for accessing the account;
Specify on which disk of your computer the virtual machine will be stored;
Allocate the amount of RAM for the VM to work;
Configure the hardware (automatically or manually).

After completing the configuration of the virtual machine, wait for the OS image to install and start working:

Microsoft Virtual PC

Microsoft Virtual PC is another popular virtual machine emulator. The program is well compatible with all versions of OS Windows. If you use a Microsoft product as your main OS, we recommend choosing Microsoft Virtual PC for emulation.

Advantages and disadvantages

Benefits of the emulator:

Excellent compatibility with all versions of Windows OS. In most cases, the user does not need to install any additional drivers for the virtual OS. All of them are synchronized with the main system;
File system sharing. Access files stored on the hard drive of the PC through the VM window;
Support for 64-bit Windows OS in the "Guest Host" and "Guest Environment" operating modes;
Support for hardware virtualization.

Disadvantages:

There are paid features. The program is distributed free of charge, but you will have to buy a subscription to support setting up a group of virtual operating systems;
There is no support for Linux-like systems.

Review of functionality and first setting of the program

To install a virtual OS, first load its image into the computer memory, and then open the Microsoft Virtual PC application. Click on the "Create a virtual machine" button and configure the following parameters in a new window:

Give the new OS a name;
Allocate space for her hard drive and the size of her RAM;
Select which devices the VM will support (networked environment, flash drives, etc.).

Outcome

We've covered the best virtual machines for Windows, but not all of them. If you think that these are not the best ones - write in the comments! Help novice readers decide which emulator to start with.

Every PC user sometimes wants to try some other operating system, but hesitates to install it on his work computer. Indeed, installing an unfamiliar OS is a very risky act. One wrong command can lose all data on the disk. But today there is a way to test several operating systems on one computer at once, and, if desired, even simultaneously! This method is called - virtual machine or virtual computer... Let's take a look at three of the best programs that allow you to use virtualization technology at home.

Understanding virtual machines

Virtualization systems that exist today have a lot in common. In particular, each virtual machine recognizes a CD drive as well as a floppy drive. In addition, it is possible to work with virtual drives and disk images. Very useful is the ability to manually set the amount of RAM for each of the virtual machines, the list of connected devices, etc. Such flexible settings allow you to comfortably use the guest system. A very convenient feature is the ability to suspend a virtual machine at any time. This frees up the necessary hardware resources for the host system.

All the differences between existing virtual machines, in fact, are reduced only to the list of supported by them operating systems, and cost... The most common systems today are VirtualBox, Windows Virtual PC and VMWare. How are they different?

ORACLE VirtualBox - versatile, free virtual machine

Virtualbox is a very simple, powerful and free virtualization tool, developed thanks to the support of the famous ORACLE corporation. Allows you to install as a "guest" almost any modern operating system, be it Windows, MacOS or any of the many representatives of the Linux family.

Creating virtual machines in VirtualBox is done with a step-by-step wizard. Any more or less experienced PC user can understand its work. The system supports networking, therefore, if desired, you can give the virtual machine access to the Internet.

VirtualBox allows you to take "snapshots" of the operating system. With their help, you can create "restore points" to which you can "roll back" the guest system at any time in case of errors or failures.

Windows Virtual PC - a virtual machine from Microsoft

Windows Virtual PC- a virtual machine to work only and exclusively with Windows. Installation of Linux, MacOS and other operating systems is not supported.

Virtual PC allows you to run several different copies of Windows on the same computer. At the same time, you can set them a priority in order to automatically allocate more resources for the needs of a particular virtual machine, slowing down the work of the rest.

The monoplatform nature of the Virtual PC virtual machine is its main drawback. However, if you want to test only programs running on Windows, this is not relevant. Some disadvantage can be considered a less functional and less convenient interface than in VirtualBox. Otherwise, Virtual PC is quite a reliable tool that allows you to create virtual machines with Microsoft Windows operating systems.

VMware Workstation - for serious tasks

VMware Workstation is a powerful, premium, premium virtualization software that supports Windows and Linux. For virtualization MacOS, this machine is not intended.

Due to its high reliability and the broadest functionality, VMware Workstation is often used not only for testing, but also for the permanent operation of virtual machines as servers, whether it be a firewall that separates an organization's network from the Internet or even a server of a database.

VMware Workstation is highly configurable, including many hardware options and networking options for working with the Internet. This system is better than others can play graphics applications on virtual machines, since it has a special virtual 3D accelerator to obtain high quality graphics.

The interface of VMware Workstation is quite well-organized, so it's pretty easy to get comfortable with all its rich functionality. The program fully supports the Russian language.

It should be noted that VMware Workstation has a free "little brother" - VMWare Player. The player does not know how to create virtual machines, but allows you to run previously created in VMware Workstation. This program will be useful in cases of testing, when, for example, the developer of an automated system will send it for review in the form of a virtual machine image. This practice is becoming more widespread as it relieves the user of the need to deploy an unfamiliar program on their own.

We got to know a little about processor virtualization technology, learned how to enable this function. Today we will continue the topic, we will install virtual operating systems on a computer, configure resources, and launch.

This issue provides a brief overview of two of the most popular shells for creating and using virtual machines. These programs are also called hypervisors.

Virtual machines can be easily and independently installed on ordinary home computers, but they are also widely used on servers.

Virtual servers with virtual remote desktops are created to solve various tasks on one physical computer.

What is a virtual machine on a PC and its purpose

For personal use it is quite suitable if you decide to master the new operating system on your own. Now you don't need to have an additional computer. There is no need to remove the familiar Windows. You can study while looking through mail and social networks and at the same time gain skills in installing, configuring new, useful and interesting programs. This is how developers test the operation of applications in new and old environments, test the operation of both operating systems and software and hardware.

But the main purpose is perhaps not this, but in the obvious economy. It is not in vain that this technology has been developed for a long time. For servers to work, first of all, you need productive equipment, which is expensive. A typical server uses its resources somewhere in the 40-60%. And if there are two or more such servers, it turns out that half of the capacity is idle.

To get rid of clustering, do not implement a bunch of physical servers and virtual machines are intended. For example, a mail server, a DNS server, a domain controller and a proxy server can be installed on one computer. With the correct calculation and configuration, you will have four servers that spin on one physical server. The physical computer will run at optimal power.

How do I set up a Hyper-V virtual machine for Windows?

The program - the hypervisor is designed to install, configure, run and manage virtual machines. In Windows 10, the developers made their own, built-in and you don't need to buy anything in this way. By default, this snap-in is not visible in the operating system and we need to install it as an additional component. To do this, in the "Control Panel" we find the link "Programs", and in it "Install additional Windows components"

We mark the necessary components with the checkboxes:

The hypervisor installation starts and the changes are applied. The system will ask for a reboot.

When rebooting, do not forget to check if processor virtualization is enabled in BIOS!

What else do we need to run a virtual operating system? We just need to find her iso image and download it to the computer. I have a Linux Fedora distribution for astronomy lovers in the form of Iso. I wonder what this operating system is? Let's find our Hypervisor first. To do this, click on the "Start" menu, go down and find "Administration Tools".

You can display shortcuts on your desktop for convenience. The manager is designed to manage virtual machines. And "fast creation" speaks for itself. We click on this shortcut. By default, the system prompts you to create a Windows 10 or Linux-Ubuntu virtual machine. But today we will look for another image, click "Change installation source":

Do not forget to specify the network adapter and the name of the virtual machine in the "additional parameters".

In the "Explorer" we are looking for our required image of the operating system:

Then we press the big blue button:

Virtual machine Hyper -V created with default parameters, usually the minimum system requirements to run. The system itself selects the number of processor cores, allocates the optimal amount of RAM, creates a VIRTUAL hard disk based on the available space. The location of the virtual machine is also automatically selected on the disk. But you can change all the settings for yourself. Before connecting, go to:

All parameters are modifiable; we carefully read what is intended and for what purpose:

Then you can connect.

Like any operating system, a virtual one also requires installation. Everything is the same as in real life :)

Typical Linux installation:

After loading the KDE graphical shell, we will continue to install the distribution kit on the VIRTUAL hard drive by selecting the appropriate shortcut:

The Hyper-V virtual machine is controlled by clicking the buttons at the top of the panel:

The buttons allow you to start, pause, shutdown, create a checkpoint, and export the virtual machine. Everything is like in a real computer :). Hyper-V will work well on server editions of Windows. True, there you need to be able to configure a lot of things. And this hypervisor crashed for me a couple of times after major cumulative updates of the "dozen". It had to be re-installed.

VM Workstation virtual machine overview, how to configure and install

Another popular solution is VM Ware Workstation. This is a very flexible software solution, I had no problems with it. It's not free. But it is lightweight and works flawlessly, it was easy to configure. Download and configure the program. On the latest editions of Windows 10, the hypervisor will not start, the program will generate an error. If you get an error when you start the virtual machine for the first time vmware player and device / credential guard are not compatible, first .

We agree with the instructions of the wizard; after installation, restart the computer. We find the launch file through the "Start" menu and click on it:

We open the program, create a new virtual machine.

We choose the usual type of installation:

Further, the wizard, as expected, will offer to install the operating system. He offers to do this either from a CD / DVD disc or from an ISO file. I have a file on disk, and I will use it. In this example, I am installing Windows XP.

When using "quick install", parameters such as computer name, keyboard layout, product key, username, account will be installed by default. This is not always convenient, and this data is corrected after installation, or at the time of creating an image of the operating system. But in the latter case, you will have to go through all the stages manually - as on a physical computer.

Do not forget to specify the name of the virtual machine and its location in the next window.

So we got to the key settings. You need to specify the size of the VIRTUAL hard disk:

Almost ready. For most operating systems, the hypervisor selects the optimal sizes of both memory and hard disk, but they can be changed later:

We start the virtual machine, after which the installation of the operating system will begin. Please note that peripheral devices connected to a physical computer can also be used in a virtual machine. Some of them (flash drives, external hard drives) will need to be connected manually through the "Virtual machine" - "Connected hardware" menu

Managing virtual machines is straightforward and straightforward. There is also a control panel located at the top of the window:

Windows XP virtual machine on Windows 10, video

Let's see an example of creating a virtual machine in a short video:

Nothing complicated! Good luck!

Why, you ask, are such software products needed? Now we will try to figure it out, and also learn how to install and configure virtual machines using the program Virtualbox.

What is a virtual machine and why is it needed?

Virtual machine (Virtual machine) - a program that emulates computer hardware, i.e. it is a kind of virtual computer on which you can install the operating system and all related software, while there will be no changes in your main operating system.

Why do we need this very virtual machine? Personally, I found two, but very significant reasons for this:

Everybody has ever wanted to see how other operating systems look like: Linux, Solaris, and just other versions of Windows. But to demolish your system is not a hunt, because suddenly you don’t like the new OS and have to rearrange it. Therefore, there is such a solution as a virtual machine, with which you can easily install other operating systems in it, and, accordingly, test them, without reinstalling your system.
Suitable for those who have already mastered the basics of the computer and want to know more, for example, how to set up a computer network? how various server services are configured, and so on, the same virtual machine will come to your aid, with which you can install several operating systems (and different!) and, so to speak, conduct experiments without harming your operating system. This greatly helps in mastering computer technologies, since a virtual machine helps to practice, unless, of course, you have several computers at home (3-4), then this is a different story.

Now let's move on to the virtual machines themselves. For home use, I prefer Virtualbox, but, of course, there are many programs such as: Virtual PC or VMware products, which, by the way, are suitable for use at work ( for those who work as sysadmins), for example, to create several servers on one computer, thereby you will save a lot of money on computer hardware. VirtualBox is free and available for download from the official website virtualbox.org

Installing and configuring a virtual machine in VirtualBox

Now let's move on to installing and configuring VirtualBox. The installation of the program itself is absolutely standard and you can install it without problems, so I will not describe this process.

After you have installed the program, run it and you will see the following window.

In the "Name" field, enter the name of your OS, for example Linux Ubuntu, and in the "OS TYPE" field, select the operating system that you will install ( I have, for example, this is a Linux version of Ubuntu) using the drop-down list and click " Further". In the next window ( picture below) it is necessary to indicate how much RAM will be on our new computer, i.e. virtual machine, you need to move the slider to the green part, I recommend leaving it by default, it is not necessary to set a lot.

We choose " Create a new hard drive", Since we do not have it yet ( i mean virtual) and put a tick “ Boot hard drive". Click "Next" and the wizard for creating a new virtual disk will start, and in this window, click " Further". In the next window, you will be asked to choose what your new hard drive will be like, " Dynamically expandable", I.e. with an increase in the amount of data on it, the size will increase or " Fixed size", I.e. constant size, I recommend choosing “ Dynamically expandable". We press " Further”, The following window will appear.

Here we indicate where the file of our virtual hard disk will be stored, I recommend storing it not on the C drive, we also set the size of our disk here, for example, I indicated 8 gigabytes. We press " Further", Then we confirm the creation of a new hard disk and click" Ready". It remains only to confirm the creation of the virtual machine.

We check our parameters for creating a virtual machine with you and click done.

Now you can start our virtual machine by clicking the " Start"And you will see a window for setting up the choice of the carrier from which we need to boot for the first time, since now we simply have nothing to boot from. Imagine you bought a new computer without an operating system installed and what you need to do from the very beginning is to install it, and for installation you need to insert the disc into the drive, but in our case you can also use the disk image with the OS.

You can select the drive in which the OS disc is inserted, or you can click on the option " Image"From which you can boot, ie. for example ISO, I select an image and press the appropriate button, as a result, you start “ Virtual Media Manager».

Click the add button and choose your image, after you have chosen the image, click the " Select". And already in the field the carrier you have the name of your image, click " Further”Then done. And finally, your image will be loaded, i.e. OS installation. Do not forget to unmount the disk image after installing the operating system so that your OS is already loaded from your hard disk, i.e. virtual hard disk. This can be done by going to the settings of the virtual machine, and specifically in the menu " Carriers". Select in the window " Information carriers"Your image and in the field" Drive unit"Put" Empty". That's basically all I wanted to tell you about the VirtualBox virtual machine.

Here is a short video tutorial in which I show you how to install VirtualBox on Windows 10 operating system.
