--- Comment #4 from Giovanni Panozzo <giodev at panozzo.it> ---
Same problem here: I have just installed a couple of Windows 10 VM. The
standard VGA driver worked quite well with virt-manager remote console. I'm
reaching these VM via 47ms roundtrip link (ADSL) with only a 1Mbps of bandwidth
from server to virt-manager.
After installing qxl driver (from Fedora iso), performance of the remote
console has extremely dropped, and virt-manager or other spice clients are now
unuseable remotely. And the video/mouse freezes forever after some minute of
spice protocol usage. Only a VM reboot can restore spice access.

I installed version 0.15 from here
https://www.spice-space.org/download/windows/qxl-wddm-dod/, but there are no
improvements.
