If your mouse pointer is not in sync with where you tap, you can use "Simulated Touchpad" input mode, or better, you can add an "EvTouch USB Graphics Tablet" to your virtual machine (when it's powered off) and then power it on. To add the Tablet:
- If configuring through virt-manager, Go to the View->Details section, and select Add Hardware->Input->EvTouch USB Graphics Tablet.
- If running your virtual machine on the command-line, you need an option similar to: "-device usb-tablet,id=input0"
