Inability to run a virtual machine with an error VERR_VM_DRIVER_NOT_INSTALLED or VT-x is disabled Most often indicates a disabled virtualization in the BIOS or a conflict with Hyper-V in Windows. When you are trying to open Oracle VM VirtualBoxThe system checks for hardware support, and in the absence of it, the program will not be able to create an isolated environment. It is with the verification of these parameters and setting up the basic environment that the correct work with this software package begins. Ignoring the initial stage of the configuration leads to the impossibility of using even the basic functions of the emulator.
To successfully start, you need to make sure that there is enough space on the hard drive, and RAM allows you to allocate resources to the guest system without compromising the host. The process of Virtual Boxing How to Use ItIt implies not just the installation of the program, but also the competent distribution of computing power of your computer. After eliminating potential driver conflicts, you can proceed to create the first virtual device.
Primary configuration and program interface
After the installation, you will see the main manager window, which looks ascetic until the first car is created. All available items are displayed here. virtualizationtheir current status and the resources allocated. The central part of the interface contains a list of projects, and on the right is a property panel, which displays detailed information about the selected configuration.
The top menu contains the basic management tools, including the section File., The machine. and Reference. In the section File. -> Settings There is a critical point where the default paths for storing disk images and system pictures are set. By default, the program uses a system drive that can quickly fill up space, so experienced users change paths to a separate partition or external drive.
⚠️ Note: Do not install paths to virtual machine storage on network drives with low response rates, this can lead to unstable guest OS operation and file corruption.
The interface adapts to the number of machines running, allowing you to switch between the console windows. For beginners, it is important to know that each running window is a separate process, consuming real resources of your CPU and RAM. Windows are controlled through standard operating system tools, but inside the interface there are hotkeys for capturing the cursor and switching modes.
Creating the first virtual machine
To start work, press the button. Create In the top panel or use a keyboard combination Ctrl+N. A creation wizard will open, which will prompt you to enter the name of the future system. When you enter the name, the program will automatically determine the type and version of the operating system based on keywords, but for the correct operation of the emulation, it is recommended to manually select the exact version, for example, Windows 10 (64-bit) or Ubuntu (64-bit).
The next step will be to allocate RAM. The slider allows you to select the amount of RAM that will be reserved for the virtual environment. The green zone on the scale indicates a recommended safe range, which can lead to braking of the main system. For modern Windows OS family, it is advisable to allocate at least 4 GB, while for light Linux distributions 1-2 GB is enough.
During the hard drive phase, you will be asked to create a new virtual drive or use an existing one. When creating a new file, you need to choose a format. Format VDI It is native to VirtualBox and provides better compatibility with state shots. Formats are also available VMDK and VHDThis is a tool that may be used to migrate machines from other hypervisors.
The key is to choose the type of storage: dynamic or fixed size. A dynamic file grows as data is filled, taking up only the actual space on the physical disk. The fixed size immediately reserves the entire declared volume, which can speed up the work, but requires free space in advance.
Installation of the operating system
After creating the configuration, the machine will appear in the list, but it cannot be started yet, since there is no boot data on the virtual disk. Select the car in the list and click Set upThen go to the section. Carriers. In a virtual optical disk drive, you need to select an image file ISO with the operating system distribution.
Start the car with a button. Launch.. A separate console window will open where the standard OS installation process, similar to installing on a physical computer, will begin. You will see the installer’s welcome screen, a suggestion to select a language and mark up the disk. For a virtual machine, disk markup takes place inside a previously created VDI file, so the data on your real computer will not be affected.
☑️ Checklist before installing OS
During the installation process, it may be necessary to enter license keys or create a user account. After the file copy is completed and the first reboot is completed, the system will prompt the installation disk to be removed. In a virtual environment, this is done through a menu. Devices -> Optical discs -> Remove the drive disc.Or simply disabling the ISO file in the media settings.
⚠️ Note: Do not interrupt the installation process of the operating system by closing the emulator window, this can lead to damage to the bootloader and the inability to start the guest OS.
Customization of guest additions
Immediately after installing the OS, the screen resolution is likely to be low, and file sharing with the main system is not available. To correct this, it is necessary to establish Guest Additions (Guest additions). This is a set of drivers and utilities that optimize the operation of a virtual machine running VirtualBox.
In the menu of the running machine select Devices -> Connect the image of the disk Additions guest OS. Inside the guest system will appear a new CD-ROM with the installer. For Windows, you need to start. VBoxWindowsAdditions.exeFor Linux, mount the disk and run the installation script from the terminal. After installation, the virtual machine will need to be restarted.
The effect of installing add-ons is obvious: it becomes possible to change the size of the emulator window, and the guest OS resolution will automatically adjust to it. It becomes available a common clipboard, Drag-n-Drop files and a throw of USB devices. Without this component, full use VirtualBox It is impossible because the performance of the graphical interface remains low.
Networking and port transfer
By default, the virtual machine operates in NAT mode, which means it has internet access through your computer’s IP address, but is hidden from the external network. This is safe for normal surfing, but not enough for setting up servers or testing network interactions between host and guest.
For more complex scenarios, the regime is used Network bridge (Bridged Adapter) In this mode, the virtual machine receives its own IP address from your router, becoming a full member of the local network. Other computers on the network will see it as a separate device. This is necessary if you are testing a web server or a network game.
| Network mode | Internet access | Visibility from the local network | Application |
|---|---|---|---|
| NAT | There is. | No (hidden) | Secure web surfing, downloading updates |
| Network bridge | There is. | Yes (full) | Testing of servers, network games |
| Virtual adapter | Only between VM | No. | Isolated laboratory networks |
Port port port setting allows you to redirect requests from a specific host port to the guest machine port. For example, a web server running inside the virtual store on port 80 can be made available at the address localhost:8080 It's on the main computer. This is done in the network settings section, tab Additionally. -> Port transfer.
Status pictures and cloning
One of the most powerful functions of the emulator is the ability to make snapshot (Snapshots) The image captures the exact state of the virtual machine at a certain point in time, including the contents of RAM and open programs. This allows you to experiment with settings or installing dubious software without the risk of damaging the system.
If the system stopped working after installing the program, you can instantly roll back to the previous image. The image manager allows you to create chains of states, returning to them at any time. It is an indispensable tool for testing updates or studying viruses in a safe environment.
How to properly manage pictures
Don’t store too many pictures in a row, as they take up space on the drive and can slow down the machine. It is recommended to take one basic picture of the clean system and periodically create new ones, removing old ones if they are no longer needed.
The cloning function allows you to create a complete copy of an existing virtual machine. You can create a full copy with all the images or a linked clone that takes up less space but depends on the original machine. This is convenient for deploying identical test environments on different computers or for creating templates.
⚠️ Note: When you delete the virtual machine, be sure to also clean the image manager, otherwise the disk files may remain on the hard drive, taking up gigabytes of space.
Frequent mistakes and their solution
Users often face an error. VT-x/AMD-V hardware acceleration is not available. This means that virtualization technology is disabled in the motherboard BIOS. To solve this problem, reboot your computer, log into BIOS/UEFI (usually F2, Del or F10) and find the parameter. Intel VT-x or AMD-Vputting him in a state Enabled.
Another common problem is the conflict with Hyper-V Windows 10 and 11. If this component is enabled, VirtualBox may not run 64-bit machines. The solution is to disable Hyper-V via “On or off Windows components” or execute a command. bcdedit /set hypervisorlaunchtype off in the command line on behalf of the administrator with subsequent reboot.
There may also be problems with USB devices if not installed. Oracle VM VirtualBox Extension Pack. This package is downloaded separately from the official website and installed via the menu. File. -> Package manager. Without it, only basic USB 1.1 devices are available, and USB 2.0 and 3.0 will not work.
To improve graphics performance in machine settings (Screen), increase the amount of video memory to 128 MB and enable 3D acceleration.
If the machine is slow, check if the memory limit on the host is exhausted. Virtualization requires significant resources, and a lack of RAM leads to active use of the paging file, which dramatically reduces the system response rate. Close the unnecessary applications on the main computer to free up resources.
Optimizing productivity
For maximum speed, it is important to properly configure the number of processors. In the section System system -> Processor You can select several CPU cores. However, do not give all the kernels to the virtual machine, leave at least one or two cores for the main operating system to work, otherwise the computer will freeze completely.
Use of solid-state drives (SSDs)SSDInstead of hard drives (HDD), it gives a huge increase in the speed of downloading and operation of virtual machines. VDI files are often fragmented, and an SSD handles chaotic reading of data much more effectively. It is also recommended to disable unnecessary services in the guest OS, such as search indexing or visual effects, if they are not needed for tests.
The main secret of stability: Always complete the virtual machine through the “Completion of work” menu inside the guest OS, not just closing the emulator window.
Regular maintenance of a virtual machine involves defragmenting the disk (if HDD is used) and cleaning temporary files, as is the case with a physical computer. Compression of dynamic disks through the utility VBoxManage It allows you to return the empty space to the host system if the files inside the guest OS have been deleted, but the disk file has not been reduced automatically.
Can I run VirtualBox on a weak computer?
Yes, you can, but with limitations. To work, you will need at least 2 GB of RAM on the host system, of which 1 GB will have to be given to the virtual machine. It is recommended to use lightweight Linux distributions (such as Lubuntu or Xubuntu) instead of heavy Windows, and to disable all visuals and 3D acceleration in machine settings.
How to transfer a file from a computer to a virtual machine?
The easiest way to install Guest Additions is to drag and drop. You can also configure shared folders in Devices -> Shared folders by pointing the path on the host. In the guest system, this folder will appear as a network resource.
Why can’t a virtual machine see a USB flash drive?
Most likely, no Extension Pack is installed or no device filter is configured. Go to the machine settings, the USB partition, make sure the controller is on (for example, USB 3.0), and add the device by serial number to the filter list, or simply select the connected flash drive from the Devices -> USB menu of the running machine.
Is it safe to run viruses in VirtualBox?
In general, yes, if precautions are taken. Be sure to disable shared folders with the host, disable the network bridge (use NAT or disable the network altogether), and don’t connect important USB media. It is recommended to take a picture of the system before launching a suspicious file to instantly roll back.
How to remove VirtualBox completely?
You need to delete the program itself through the standard uninstaller, and then manually delete the configuration folders (usually in C:\Users\Name\.VirtualBox) and virtual machine files if they are no longer needed. It is also worth checking the list of network adapters in the system and removing VirtualBox Host-Only virtual cards.
