VirtualBox Guest Additions offer the following features: • Enable users to seamlessly move mouse pointer between host and guest. Users don’t have to press the Host key (right Ctrl) to free the mouse pointer from being captured by the guest OS. ![]() Jul 3, 2018 - VirtualBox Guest Additions are a collection of device drivers. First start by updating your Ubuntu guest operating system software. Next, you will get a dialog window, prompting you to Run the installer to launch it. MacOS Sierra, the first of the new macOS systems, includes the ability to create a bootable installer on a USB flash drive or on a drive you have connected to your Mac. The advantage of the ability to create a bootable installer of macOS Sierra can’t be overstated. I was able to make a macOS Sierra external USB boot disk in a few minutes, and the installation worked without a hitch. Also works with older versions of OS X. Diskmaker X is a popular app. Click “Create Installer.” When it’s done, insert your USB drive into any Mac, then launch the installer by holding down the Option key when you boot up your computer. After creating the bootable installer, follow these steps to use it. Connect the bootable installer to a compatible Mac. Use Startup Manager or Startup Disk preferences to select the bootable installer as the startup disk, then start up from it. Your Mac will start up to macOS Recovery. Create a boot usb drive for mac os sierra. • Enable the guest OS to have read and write access to a folder on the host OS. • Power up the graphics ability of your guest machine. The screen resolution of guest can be automatically adjusted and 3D graphics can be accelerated. • Enable bidirectional shared clipboard between host and guest. Basic Idea Behind Installing Guest Additions The guest additions are a set of device drivers (graphics and mouse drivers) and system applications that is going to be installed in the guest OS. One of them is a VirtualBox kernel module. This kernel module must be compiled in the guest OS. So the installing process is as follows: • Install development tools on the guest OS to enable us to compile kernel module. • Download the guest addition ISO file on the host and insert it to the guest’s virtual CD-ROM drive • Compile and install it on the guest OS. Why Do I need to compile VirtualBox Guest Additions kernel module? The binary compatibility of kernel module depends on the API of Linux Kernel. Since the API of each version of Linux kernel might be different, it’s better to compile the kernel module rather than providing a bog-standard kernel module binary. Why can’t I just download guest additions onto the hard disk of guest machine and compile it? The VirtualBox Guest Additions are provided as a single CD-ROM image file which is called VBoxGuestAdditions.iso. Ibm 3270 emulator. Step 1: Prepare Fedora Guest System for Compiling software Fully update Fedora guest. Sudo dnf update && sudo dnf upgrade Install DKMS, GNU C compiler, kernel-headers and kernel-devel. They are required if you compile Linux kernel modules. Dkms enables automatic re-compiling when a new kernel is installed. Sudo dnf install dkms gcc kernel-devel kernel-headers Reboot Fedora guest. Sudo shutdown -r now Step 2: Insert Virtualbox Guest Additions ISO file to Virtual CD-ROM Drive In the VirtualBox window, select Devices > Insert Guest Additions CD image. Oracle VM VirtualBox is an easy way to use multiple OS on a single window. You can install many Operating Systems on Virtualbox Virtual Machine. Like- Windows, Linux, Solaris, BSD, IBM OS/2, Mac OS X2 & others etc. But after install, when we start any virtual machine then the problem is- it starts with a small screen. We choose full-screen mode but faces resolution problem. It is because when we installed any OS on the virtual box then Virtual Box doesn’t automatically install the drivers. We need to do this manually.
