A virtualized display device is usually viewed with the vncviewer application, either by 'xm vnc domU' or with vncviewer localhost:port. vncviewer and the RFB protocol provides absolute coordinates to the virtual display. These coordinates are either passed through to a PV guest or converted to relative coordinates for a HVM guest. A PV guest receives these coordinates and passes them to the kernels evdev driver. There it can be picked up by applications such as the xorg-input drivers. Using absolute coordinates avoids issues such as guest mouse pointer not tracking host mouse pointer due to wrong mouse acceleration settings in the guests X display. Advertise either absolute or relative coordinates to the input system and the evdev driver, depending on what dom0 provides. The xorg-input driver prefers relative coordinates even if a devices provides both.
