Since qemu-2.3.0 -- qemu-3.0.0. I find weird phenomena about windows's paint software cross-shaped cursor offset a pixel since qemu-2.10.0, but it is ok before the version of qemu-2.10.0. Only spice agent and service are running in guest windows since qemu-2.10.0, windows's paint software cross-shaped cursor offset a pixel is the same as the windows's paint software cross-shaped cursor focus point is the same as the true windows machine instead of virtual windows machine. +What does QEMU change since qemu-2.10.0? It is the changes that result in windows's paint software cross-shaped cursor is not accurate with true windows machine for comparison. +The following is the full command line used to launch the QEMU guest: +# /usr/bin/qemu-system-x86_64 -m 4096 -smp 2 -M pc -name win7-6904 -hda /home/win7_kvmgt.img -bios /usr/bin/bios.bin -enable-kvm -k en-us -vga qxl -display egl-headless -spice disable-ticketing,port=6904,streaming-video=all -machine kernel_irqchip=on,usb=on -global PIIX4_PM.disable_s3=1 -global PIIX4_PM.disable_s4=1 -cpu host -device usb-tablet + +BTW, guest windows display card is QXL driver. +But the following full command line used to launch the QEMU guest is OK.
