I created a VM (host: Fedora 25, guest: LUbuntu 16.10) using virt-manager. When I start it and click on the window, I see two cursors: one host cursor and another guest cursor:
The movement of the guest cursor is restricted by the host cursor because it can't leave the screen boundaries. Also, sometimes the guest cursor doesn't appear and then I can't use mouse to interact with the guest (the keyboard still works). The offset of cursors isn't constant. I can move the guest cursor around the host cursor by moving the mouse fast in one direction and then slow in the opposite.
How can I make the host cursor disappear when I want to interact with the guest?
