Passing on the cursor sprite needs the hotspot information, so spice client can position the cursor correctly. I didn't got hotspot information in my testing yet, but maybe the guest kernel was too old. Is that supported meanwhile? If so, which kernel version is needed? Spice already has support for setting pointers, we can simply use that, at least initially. Doesn't use dma-bufs. If it turns out to be a performance issue we can add support for using dma-bufs instead, but that needs spice server changes. > And really like to see dmabuf support could be in upstream soon. Do > you have any predict for which qemu version? I want have this in 2.12, at least the current, initial version. Improved cursor support might take a little longer. cheers, Gerd
