Automated logins: Basically credentials passing, it can be a useful feature.The parameters of the time synchronization mechanism can be configured. Time synchronization: The Guest Additions will resynchronize the time with that of the Host machine regularly. ![]() Applications can be started on the Guest machine from the Host. The “guest properties” provide a generic string-based mechanism to exchange data bits between a guest and a host, some of which have special meanings for controlling and monitoring the guest. ![]() Generic host/guest communication channels: The Guest Additions enable you to control and monitor guest execution.Seamless windows: The individual windows that are displayed on the desktop of the virtual machine can be mapped to the host’s desktop, as if the underlying application was actually running on the host.The video resolution in the guest will be automatically adjusted, as if you had manually entered an arbitrary resolution in the guest’s Display settings. It also allows you to resize the virtual machine’s window. Better video support: The custom video drivers that are installed with the Guest Additions provide you with extra high and non-standard video modes, as well as accelerated video performance.You can ask VirtualBox to treat a certain host directory as a shared folder, and the program will make it available to the guest operating system as a network share, irrespective of whether the guest actually has a network. Shared folders: This feature allows you to exchange files between the host and the guest.Drag and drop: You can also drag and drop files between the host and the guest OS.Shared clipboard: With the Guest Additions installed, you can copy-paste between the guest and the host operating systems.Mouse pointer integration: You no longer need to press any key to “free” the cursor from the Guest OS.Don’t believe me? Here are the important features that the Guest Additions offer: ![]() With VirtualBox Guest Additions enabled, using the virtual machine becomes a lot more convenient. Why Should You Use VirtualBox Guest Additions? The guest system is the virtual machine you have installed inside your host operating system.īefore you see the steps to install VirtualBox Guest Additions on Ubuntu, let us first talk about its features. My host OS is Windows 7 64-bit, and I'm running VirtualBox 4.1.18.The host system is your actual operating system installed on your physical system. I tried increasing it to 256MB, but with no effect: the guest is still six pixels too narrow. When I created the VM, its display memory was already defaulted to 128 MB. This answer suggested giving the VM 128MB of video memory, and claimed no problems getting 1366x768 afterward. I'm using version 4.1.18 and seeing the same problem they claim to have fixed, so either they broke it again, they were wrong about ever having fixed it, or my problem is something else entirely. This user had the same problem, but the accepted answer is "install the Guest Additions", which I've already done that got me to 1360, but not to 1366.Īccording to the VirtualBox ticket tracker, there used to be a bug where the guest's screen width would be rounded down to the nearest multiple of 8, but they claim to have fixed the bug in version 3.2.12. So there's a three-pixel black bar at the left and right sides of the display. When VirtualBox is "fullscreen", the guest is only 1360x768 - six pixels too narrow. The problem is, VirtualBox refuses to run the guest at 1366x768. Windows 8 disables some of its features if the resolution is less than 1366x768, so I need to run the guest OS fullscreen. I'm trying to run Windows 8 in VirtualBox. ![]()
