Some more details would be useful.
As the cursor hotspot is something the h/w does not care much are
you basically saying the userspace (X/wayland) will pass this
information to kernel driver (Intel) which will write to the mmio
page which will be used by Qemu to pass to spice-server, right?
I assume this will require changes in kernel (Intel) driver and
Qemu, right?
