How to install Vbox extensions on RHEL 8.5 guest on Windows 10 host

[pjfarley3]

I seem not to be able to discover how to install Vbox extensions on a newly installed RHEL 8.5 VM. All references on the net talk about mounting the Vbox extensions CD, but there is no such animal any more.

Current Vbox version is 6.1.20 (can install 6.1.32 if that makes a difference).
Windows 10 21H2 build 19044.1526

RTFM or other pointers welcome.

On the contrary, the Guest Additions CD in very much alive and is available for every release on VirtualBox. It comes as a CD image with every release and can be attached to the vm's virtual disc drive very easily.

From the vm window click the Devices tab and select the Insert Guest Additions CD Image from the dropdown list, then run the installer from within the vm.

My apologies, you are absolutely correct. I was remembering much older versions where the extensions were delivered as an ISO while the newer extensions are delivered as extpack files.

Thank you for the hint, and again apologies for my ignorance.

You've got two different entities cross-wired in your mental database.

Guest Additions come as an ISO bundled with Virtualbox, and gets installed in the VM, the guest, through the VM's CD drive.

The Extension Pack is a different-license separate download, with an .extpack extension, and is installed inside Virtualbox on the host, to extend Virtualbox's capabilities. See the main Virtualbox window, File menu, Preferences, Extensions. Virtualbox needs admin privileges (on Windows hosts at least) to install the Extension Pack.
