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.

Don’t forget to add a custom screen size to the VirtualBox virtual machine (step 1).VirtualBox is an open-source, multi-platform application developed by Oracle, primarily used as a virtualization tool for x86 hardware. If you want to work with different resolutions, you just have to add the corresponding entries to the GRUB boot menu. Press ESC and then SHIFT+ZZ to save the new GRUB boot menu.įrom now on, your Android VM should use the new screen resolution.Īndroid on VirtualBox with changed resolution.Press the i key (enables insert mode in the vi editor), and then type UVESA_MODE=360圆40.

Move the cursor to the first line that begins with kernel /android.

At the Linux prompt, enter the following commands:.

Wait until the Linux boot process is completed, and then press Enter.

Start the VM and, when the GRUB boot menu appears, select the Debug mode.

I assumed here that the name of your VM is Android.

Add a custom screen resolution to your VirtualBox VM by opening a command prompt, navigating to your VirtualBox installation folder, and entering the following command:.
