Indeed, the synaptics driver is not installed in VirtualBox and on
real hardware but is installed in KVM and installing it causes the
issue.

I am not sure if this is a failure in the driver to recognize
compatible devices or if the PS/2 device in KVM has incorrect
identification. I never quite understood how it is posible to tell
aprat different PS/2 devices from the system's side.
