In VirtualBox, with Addition CD Image installed, you can enable the feature of Shared Clipboard and Drop'n'Dop to copy/cut text between host and guest.
I can use both clipboard and Drag'n'Dop from host Windows 10 to guest Ubuntu, clipboard from guest Ubuntu to host Windows. BUT NOT Drag'n'Drop from guest Ubuntu to host Windows, it make the guest Ubuntu hang-up! http://android-er.blogspot.com/2015/10/share-clipboard-and-dragndrop-between.html
