But you surely want a mouse pointer for the admin?
You render it directly to the primary surface then I guess?

Hmm, maybe we should have a ioctl to configure the refresh rate, or a
ioctl to allow qemu ask for a refresh when needed?
qemu can throttle the display update rate, which for example happens in
case no vnc client is connected. qemu updates the display only once
every few seconds then.
cheers,
Gerd
