Sorry for the lack of response. Do you still see this on an f23+ host with f23+ VM?
Comment 2 Peng Wu 2016-05-03 02:15:21 EDT
I tried on F23 host with F23 VM, the bug still exists.
Comment 3 Cole Robinson 2016-05-14 11:45:09 EDT
Thanks, I can reproduce. This seems to be related to relative mouse handling, using -usb tablet will 'fix' it and give better mouse interaction anyways.

rhel6 guest works as expected, so maybe this is a qxl or modesetting driver regression. -vga std is also affected
Comment 4 Cole Robinson 2017-03-24 13:51:29 EDT
With F25 qemu and F25 guest this doesn't seem to be an issue anymore, with that minimal command line. I think F25 guest + vmmouse is better coordinated now, since using vmport=off gives crappy behavior again (but vmmouse=on is the qemu default)
