Title:
windows's paint software cross-shadped cursor offset a pixel in guest
windows which is generated by qemu-kvm
Status in QEMU:
Expired
Bug description:
I have already tested lots of versions of QEMU. 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. For
comparison, I pasted it below (Just add vdagent and spicevmc in the command
line to make sure spice service and agent is running in the guest windows):
# /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 -device
virtio-serial-pci,id=virtio-serial0,max_ports=16,bus=pci.0,addr=0x5 -chardev
spicevmc,name=vdagent,id=vdagent -device
virtserialport,nr=1,bus=virtio-serial0.0,chardev=vdagent,name=com.redhat.spice.0
