Comment 6 for bug 1670652

Don't get me wrong, I know not containing the pointer is preferable in some cases, what I'm saying is lacking, is an *option* to contain it.

The pointer edge gestures in unity8 require "pushing" your pointer against the display edge, this is only possible in a VM if the cursor is confined.

Trying with virt-manager, I've not found a way to confine the pointer. I'll try again using some of the options in the discussions linked.
