I use VirtualBox 5.2.6
on Windows 10
. There is an Ubuntu
virtual machine, from which I would like to access to host's clipboard and files.
I tried to use
Machine>Settings >> General>Advanced>Shared Clipboard
I also tried
Devices>Shared Clipboard>Bidirectional
I installed virtualbox-guest-dkms
too, but has no effect.
You need first to install guest addition in your VM, you may take a look here if you need help.
