Configuring a virtual machine

VM VirtualBox is free and open source virtualization software that allows users to run multiple operating systems on a single computer. It was created by Oracle Corporation and is available for Windows, macOS, Linux and Solaris.

With VirtualBox, users can create virtual machines (VMs) that emulate a complete computer system with its own hardware resources, including CPU, RAM, hard disk, and network interface.

How is the configuration done?

To manage network functions, you need to select the desired virtual machine, call it up and select the "Configure" section and the "Network" section. Next, activate the network adapter and specify "NAT" in the connection type.

To connect the virtual machine to the underlying system - you need to select "Network Bridge" in the connection type. Thus, the virtual machine will be connected as a full-fledged device in the main network.

What problems with virtualization can there be?

Even if the installation was successful and without errors, problems may be waiting for you at the very beginning of using the VM (or after some time). For example, you may encounter a "hardware acceleration" error in your system when you start the OS. Such a problem is solved by enabling virtualization in BIOS. If VirtualBox does not start for some reason, but also does not give any error, such a problem can be solved by reinstalling or rolling back the application, you can also try uninstalling updates.

If you encounter an error or BSOD, then the solution may be to disable the Hyper-V hypervisor. You can do this by using the command line and just one command entered. Do not forget that it is recommended to reboot the system after each intervention in the system settings.

In the case of errors with kernel driver, the virtual machine may have problems with startup, in which case updating VirtualBox or reinstalling it should help. If the error appears because the kernel driver is not installed ("Kernel driver not installed") - then turning off Secure Boot may help.

Don't forget that many problems or errors can occur due to incorrect settings. For example, if theUEFI Interactive Shell launches instead of the selected VM, you should check the "Enable EFI (special OS only)" option in the "System" section of the settings.
