kvm + Vnc + Mouse pointer sync issue

While we use the Vnc we could see that the mouse pointer in the Vnc Viewer is not sync with  the system Vnc.

This can be solved by adding the option -usbdevice tablet  along the kvm command

Example

$KVM -m 2048 -smp 2 -cdrom $ISO -drive file=$VIRTIO_ISO,index=3,media=cdrom  -drive file=$IMAGE,if=virtio,boot=off -boot d -vga std -k en-us -vnc 10.1.17.42:1 -usbdevice tablet

Make sure that the setting in the controller and compute node are correct and also double check the IP's.  And replace the host-name with the IP.
