1. Letting the VM-viewer window-system draw the cursor as it normally

would draw it.

Why is this important? Can't the VM viewer hide the cursor and use a sub-surface to manually draw the cursor plane configured by the guest?

Because then moving the cursor as seen by the user requires a round trip through the VM and that adds latency, esp. when the VM viewer is viewing a VM which is running somewhere else over the network.

The video output has latency anyway.

Sounds like you've never tried the two different modes yourself? :) IME it makes a big difference even with a local VM. Even very little latency can make the cursor feel awkward, like it's being held back by a rubber band or something.
