Installing a VirtualBox virtual machine requires pre-checking the activation of VT-x or AMD-V technologies in the BIOS, since without this step, the emulator simply will not run the guest operating system. Many users make the mistake of starting the installation immediately from the installer’s boot, ignoring the need for hardware virtualization support from the CPU. If you miss this stage of diagnosis, you will encounter an error code. VERR_VMX_NO_VMX or similar report of the hypervisor being unavailable. Only after making sure that hardware resources are available, you can proceed to download the distribution from the official developer repository.
The process of deploying a virtual environment on a host machine is a sequence of actions, each of which affects the stability of the emulated environment. Modern software requirements dictate the need to use isolated spaces to test software, analyze malicious code, or work with incompatible versions of the OS. Oracle VM VirtualBox It remains one of the most popular solutions due to its open source and cross-platform.
Before the manipulation, you need to free up disk space, since guest system images can take from 10 to 100 GB depending on the tasks. It is also worth checking the availability of free RAM, since the allocation of resources occurs statically or dynamically, but always to the detriment of the main system. Properly prepared user workstation ensures that drivers and network adapters do not conflict at later stages of configuration.
System Preparation and Downloading of the Distribution
The first step is to download the current version of the software from the official website, which eliminates the risk of introducing modified malicious code. The architecture of your computer’s processor must match the distribution version, although in most cases, modern systems use the standard. x64. Downloading the main installation package is only half the battle, since a full-fledged work will also require an extension package. Extension Pack.
This additional component provides support for USB 2.0 and 3.0, disk encryption and remote access protocols, without which the functionality of the program is significantly reduced. Ignoring the extension installation will make it impossible to connect external drives inside the virtual machine. The Extension Pack version must strictly conform to the version of the main application, otherwise there will be version conflicts.
⚠️ Warning: Never download installation files from third-party torrent trackers or file sharing sites, as this compromises the security of the entire host system.
Checking the integrity of downloaded files through hash amounts is a good practice, especially if the download was interrupted or was carried out through an unstable connection. After successful installation, you can start the installer directly, which will automatically determine the parameters of your system.
Installation process and selection of components
Running the installation wizard opens the welcome window where you need to confirm the interface language and the path to the destination folder. By default, the program offers to install all components, including network drivers and USB support, which is the optimal choice for most use cases. Refusal to install network components Oracle VM VirtualBox NDIS6 Bridged Networking Driver It will deprive the machine of access to the local network.
During the installation, the system may request confirmation to install additional network interfaces, which is normal behavior for virtualization software. These interfaces allow the machine to see the network as if it were physically connected to the router by a separate cable. The file copying process takes a few minutes and depends on the speed of your drive.
☑️ Ready for installation
At the final stage, the wizard will offer to start the program immediately after the window closes. It is recommended to leave this option active to move to the initial setting immediately. In some cases, it may be necessary to restart the host system to activate low-level drivers, which the system will notify you separately.
Creation and configuration of a virtual machine
After the first run, you will see the main manager window where you need to press the button. Create To initiate a new project. The wizard will suggest entering a machine name that will automatically substitute the type and version of the operating system if they are recognized by the name. Choosing the right OS type is important for applying optimal default settings.
The key point is the allocation of resources: the amount of RAM and the number of processor cores. It is not recommended to allocate more than 50% of the available resources of the host, so as not to cause a drop in the performance of the main system. Basic memory It should be sufficient for the guest OS to work, but not redundant.
| Parameter | Minimum value | Recommended value | Impact on the system |
|---|---|---|---|
| RAM | 512 MB | 2048 MB | High (critically) |
| Processor cores | 1 | 2 | Average. |
| Video memory | 16 MB | 128 MB | Low (for GUI) |
| Disk space | 10Gb | 40 GB+ | Depends on the OS. |
Setting up video memory and enabling 3D acceleration are essential to properly display the guest system’s graphical interface, especially if it’s Windows or modern Linux distributions. Without hardware acceleration, the interface can handle delays or artifacts. These settings can be changed later in the settings menu of a particular machine.
Network setup
The mode of operation of the network determines the machine's access to the Internet. NAT allows you to access the network through the host, Network Bridge makes the machine a full-fledged node in the local network, and Internal Network isolates the machines among themselves.
Installation of the guest operating system
Having created an empty shell, you need to connect the installation image of the operating system through the media settings. In the section Carriers You need to select an empty optical drive and indicate the path to the file. .iso with an OS distribution. This action is equivalent to inserting the installation disk into the real drive of the computer.
Once you start, the machine will start booting from the virtual disk, initiating the standard operating system installation process. The user goes through all the stages: language selection, virtual hard drive markup and account creation. From the point of view of the guest OS, it is installed on a regular computer, unaware of virtualization.
⚠️ Note: Be careful when choosing a disk to install inside the guest system, so as not to accidentally format partitions of the main computer if the drive throw is configured incorrectly.
Completion of the installation takes the same time as on a physical computer and depends on the speed of the host disk subsystem. After the first boot, the system can run slowly, as the virtual hardware drivers are not yet optimized. It is to address this problem that the next important stage is reached.
Installation of guest OS (Guest Additions)
For the full integration of the guest system into the host environment, it is critical to install the package. Guest Additions. It is a set of drivers and utilities that allows the machine to understand that it is running in a virtual environment and use resources more efficiently. Without this package, it is impossible to change the size of the window with automatic change in screen resolution.
Installation is done through the menu Devices -> Connect the disk image of the guest OS Add-ons inside the running machine. In the guest system, a new CD-drive will appear, from which you need to start the installer. In Windows, it's a file. VBoxWindowsAdditions.exe, in Linux, script VBoxLinuxAdditions.run.
After installing add-ons, be sure to restart the virtual machine so that the video and input drivers start working correctly.
The functionality of the add-ons includes a shared clipboard, drag and drop files (Drag'n'Drop) and create shared folders. These capabilities make work between the main and virtual seamless systems, allowing data to be easily transferred. Ignoring this step leaves the user in an isolated, low-resolution environment.
Installing Guest Additions is a must-do step without which using a virtual machine is considered incomplete and inconvenient.
Setup of shared folders and integration
The organization of file exchange between the host and the guest is implemented through the mechanism of shared folders, which is configured in the properties of the virtual machine. You can select any directory on the main computer and make it available inside the guest system as a network resource. This eliminates the need to use external media or cloud services.
To access the shared folder in guest Windows, you need to connect the network disk, indicating the path to the resource. In Linux systems, the folder is usually mounted in /media/sf name foldersHowever, the user must be added to the group. vboxsf. Access rights are governed by the security settings of the host system.
Integration also allows the use of the clipboard in bidirectional mode, which greatly speeds up copying text and commands. The setting of these parameters is in the menu Common exchange buffer and Drag'n'Drop in the device section. It is recommended to include these features only in trusted virtual machines.
Solving Typical Problems and Errors
During operation, users may encounter an error. VT-x is not availableThis indicates a conflict with another hypervisor, such as Hyper-V or Sandbox Windows. In Windows 10 and 11, you need to disable Microsoft hypervisor components via “On or off Windows components.” Without this step, VirtualBox will not be able to run 64-bit guest systems.
USB problems are often solved by installing an Extension Pack and adding a current user to the group. vboxusers (on Linux hosts). If the device is not defined, try changing the USB controller standard in the machine settings from 1.1 to 2.0 or 3.0. Device filters allow you to automatically connect specific devices when you start the machine.
⚠️ Note: When you update your host system or VirtualBox itself, old status shots (Snapshots) may become incompatible, so back up important virtual machines before upgrading.
If the guest system is slow, check the host’s power settings and make sure the virtual drive is not fragmented (for HDD). Use of solid-state drives SSD Virtual machine file storage (.vdi) provides up to 300% performance gains over mechanical disks.
Status pictures
Snapshots allows you to save the state of the machine at a certain point in time. It’s convenient to test, but the chains of images take up a lot of space and can slow down the drive.
How to increase the size of a virtual hard disk?
Use the command to expand the disk VBoxManage modifyhd in the command line of the host system, having previously deleted all pictures of the state of the machine. After changing the .vdi file size, you need to go to the management of the guest OS disks and expand the partition to empty space.
Why is the common exchange buffer not working?
The problem is often in an untried process. VBoxClient inside the guest system or the absence of installed Add-ons of the guest OS. Check the settings in the Devices menu and make sure there is a tick “Bidirectional” for the clipboard.
Can VirtualBox run on macOS with an M1/M2 processor?
Native support for ARM-processors Apple Silicon appeared only in the version of VirtualBox 7.0, but the functionality is limited. For an x86 architecture on a Mac with M1/M2 chips, it is better to use emulators like Parallels or UTM, as VirtualBox does not emulate x86 instructions on ARM without significant performance loss.
