I'm using the Fedora 39 Linux distribution on an HP laptop and I also have it installed on a VirtualBox on my work computer. Today I will show you a way to solve copy paste between content on your computer and Fedora 39 on VirtualBox.
This requires Virtual Box to be set to bridge network as in the attached image.
The next step is to have the Cockpit tool installed, see instructions here.
Open the web address created by the Cockpit tool in your computer browser and go to the Terminal section. This way you will be able to transfer text content using your computer's browser and not the VirtualBox settings.
