The Virtual Machine Guest Addition is a very vital component to be installed on a VM in order to enable more advanced functionalities (capabilities) of a VM.
See one of the reasons to have Virtual Machine Guest Addition installed on a VM, see https://techdirectarchive.com/2020/03/21/how-to-copy-and-paste-between-a-host-machine-and-virtualbox/
First, insert the virtual machine guest addition. Since I am demonstrating this on macOS, perform the following steps.
– Click on Device
– Click on “Insert Virtual Machine Guest Addition CD”
After the Virtual machine Guest addition is mapped to the VM
Double click on the VBoxWindowsAddition as shown above
– This will launch the setup wizard to install the guest addition as shown below.
Decide a location to have the guest additions installed.
Click on next and continue through the installation
The components to install are already selected,
– Click on install
The installation process will continue and will prompt you to rebot after the installation is complete
Now reboot the VM, and this will have the VM guest additions applied to your VM.
Now, you will now be able to perform advanced functionalities such as copying between host and VM etc.
