So, is it possible to increase the screen resolution and make the guest operating system run on full screen in the host machine? Well, of course, you can make the guest OS screen larger and even increase the resolution. But by default, the screen resolution appears very small upon installing the guest operating system, as demonstrated in the image below.Īnd using the guest OS on such a small resolution is an uncomfortable job. One of the key features of VirtualBox is that it supports multiple screen resolutions. Is it resource-intensive? No, it has built-in software virtualization technology that makes it less dependent upon host hardware. VirtualBox can host many operating systems at a time.
