Resolving this question involves having guest additions on a MacOS guest. If, instead, you want to install guest additions from a MacOS host onto a non-MacOS guest:You can copy the guest additions iso from your machine.
Essentially, you need to unmount your virtual cd drive before inserting the guest additions cd image. The linked article provides instructions for doing this. Hitting the 'Force Unmount' button would be another way to unmount your drive, and after doing that the insert guest additions cd menu option should work the second time you use it.

The problem happens when we select Devices > Insert guest additions CD image. But instead, if you go to Devices > Optical Drives, you'll see the guest additions ISO. Simply select it and it'll automatically prompt you and run the installation.
Should you decide to create your own VirtualBox installation of Kali Linux (rather than using our pre-made VirtualBox images), and you want to force a manual reinstall of virtualbox-guest-x11 (as something has gone wrong), first make sure you are fully updated, then enter the following.
Once the guest additions is installed, press Enter to close the terminal window and restart your Linux Mint virtual machine. Now the resizeable display should be working. The screen resolution of Linux Mint VM will adjust with the size of VirtualBox window. You can press right Ctrl and F keyboard shortcut to enter full-screen mode. You can now also configure shared folder and bidirectional shared clipboard.
newbie here-I googled a lot and watched a bunch of youtube videos but could not solve my problem of guest additions not working after installation of ubuntu and its associated guest additions , then i tried mint, did not work in the beginning after installing of guest add.
This article is short and consise: -guest-additions-iso-downloadI had to do what Johnathan suggested and install the kernel devel packages, and then re-install the guest tools before mouse integration worked
Technically dkms is not required for the Guest Additions to work. But if you do not install the package, the Guest Additions would stop working after the next VM kernel update. So it is better to install this package right away (it must be installed before installing guest additions).
Another way to install the guest additions is to enable the rpmfusion-free repo and install them as any other package:$ sudo dnf install -free-release-$(rpm -E %fedora).noarch.rpm$ sudo dnf install VirtualBox-guest-additions
Let's look at how to create VirtualBox full screen for Linux guests using Ubuntu as an example. You may install VirtualBox Guest Additions on Linux by putting the ISO disk image into a virtual CD/DVD drive of a VM and executing the installer for the relevant platform, as explained in the first section for Windows. In our blog post on installing Ubuntu on VirtualBox, we discussed this way. It is possible to install Guest additions from online package repositories using your package manager, although there are currently certain drawbacks due to package dependencies. As a result, it is now suggested that you install Guest Additions from a virtual ISO drive.
According to the debian repo search ( ), the guest package name is virtualbox-guest-dkms . That said, the end result should be quite similar between using the guest dkms package and the iso. In theory, the iso would work on non-debian systems (without dkms), while the dkms version is likely to better stay up to date automatically with new kernel versions (or new Vbox versions).
The VirtualBox app itself is both small-f freeware and capital-F Free Software, and so are its optional Guest Additions, which enable host/guest integration. Many Linux distros include their own builds of the guest additions, but if you install them from VirtualBox itself, version 7 has preliminary support for automatically updating them in guests.
Note that the list of supported guests is constantly evolving such that an operating system not listed above may still be able to run the VirtualBox Guest Additions. As a general rule, it won't do any harm to try the guest additions even if the guest is not listed as being supported.
As previously discussed, the VirtualBox Guest Additions reside in an ISO image file which is bundled with the VirtualBox software. This image file must be mounted as a virtual CD-ROM on the virtual machine on which the additions are to be installed. VirtualBox provides a shortcut to performing this task in the form of the Devices->Install Guest Additions.... menu option. When selected, this option mounts the VBoxGuestAdditions.iso as a virtual CD-ROM and, assuming that AutoPlay is enabled on the guest Windows operating system, the VirtualBox Guest Additions installer will automatically start. If AutoPlay is not enabled, navigate to the CD-ROM using Windows Explorer and double click on VBoxWindowsAdditions.exe to initiate the installation process. Once invoked, the Sun xVM VirtualBox Guest Additions Setup Welcome screen will appear. Click Next > to proceed to the license screen, review the license and click I Agree to display the installation screen as illustrated below:
Once the installation is complete, the guest operating system must be rebooted for the guest additions to take effect. The reboot may be initiated from the Setup screen, or performed manually at a later, more convenient time.
The VirtualBox Guest Additions for Linux guests require that the packages necessary to facilitate the building of Kernel modules be installed prior to installing the guest additions. This include the GNU C Compiler and kernel development sources. These are typically installed by default on Ubuntu distributions. On Red Hat, CentOS and Fedora systems however, this can be achieved by executing the following command as super user:
The default behavior of the Linux VirtualBox guest additions is to install all the components. Select components may be installed by running the installation script (either VBoxLinuxAdditions-amd64.run or sh VBoxLinuxAdditions-x86.run) with one or more of a number of command line options, for example:
To rebuild the VirtualBox Guest Additions Linux kernel modules, mount the guest additions CD-ROM ISO image if it is not already mounted, change directory to the mount point and run one of the following commands:
VirtualBox is extremely horrid for running Mac VM guests, the most polite comment I can provide is that it can be done. Apart from the lack of Mac guest additions, you can only allocate a single CPU core, you are limited to a specific screen resolution, speed is awful, and I am not even sure copy&paste works. If it was a dog you would have it put down. On top of that the process to install OS X in to a VirtualBox VM requires having the OS X installer as an ISO image. Since OS X has not come on DVDs or ISOs since Lion was released this means even more hard work on your part converting the installer in to an ISO. (VirtualBox is very fussy about the format/contents of the ISO.)
VirtualBox guest additions is a collection of device drivers and software application package which is shipped with Oracle VirtualBox. They need to be installed inside a VM to improve the performance of the guest operating system and to add extra features.
VirtualBox guest additions are stored in an ISO image VBoxGuestAdditions.iso format inside the VirtualBox installation directory. To install the Guest additions, you need to mount the ISO image in your VM.
I run the new version of Ubuntu 20.04 as a Virtualbox guest machine on my macOS Catalina Hackintosh. It runs very well, the VirtualBox installation also without any problems. Now I will show you how to install the VirtualBox Guest Additions on Ubuntu 20.04. Ubuntu 20.04 does not ship with guest additions.
Now, we are ready to install the Guest Additions. From the VirtualBox window, go to Devices >> Insert Guest Additions CD. Now switch to the Ubuntu guest additions and you should see a notification window.
In my case, the disk is named VBOXADDITIONS_4.1.10_76795. This name may vary depending on the version of VirtualBox you have installed. Now uninstall the guest additions (don't forget to adjust the path):
You can uninstall the guest additions just like any other program on a Windows machine: Click on Uninstall a program in the Control Panel and search for the version you installed. Select it and click on the Uninstall button above the program list. 2ff7e9595c
