This can happen for several reasons, but the most common is that the operating system has not been correctly adapted to the virtual machine and that, therefore, do not have the necessary drivers for the operating system to work correctly. However, you should not worry about it, since VirtualBox always includes the possibility of installing the so-called “Guest Additions” to solve this problem.
