In a libvirt aware app like virt-manager/virt-viewer the VNC client can of
course query the XML description for the guest & determine what pointer
devices are available to the guest. Ultimately you've still got the issue
of whather the guest OS is configured to use a device, so best we can do
is make a reasonable guess / offer choice to the user.
