Hi Pavel,
I have installed the latest nightly build but I have not seen any difference to adjust spice options:
I have not experienced any performance improvement... Just, from the virt-manager I'm not able to see my windows 10 desktop (it is completely black) XS
Am I looking at the correct place?
From Remote Viewer I can see the desktop as usual (I'm upgrading windows):
May I revert the spice install in order to make my virt-manager work properly again?
Thanks a lot.

Hi Pavel,Yes, in my configuration I have already set:vram: 64MBstreaming mode='filter' <-- I have tested with 'all" as well with the same resultsimage compression='auto_glz'When I connect through the Internet or from my home wi-fi (54Mbps) In the logs I can see "LOW BANDWITH" detected, and the video performance is really bad.Thanks a lot.2017-03-09 13:14 GMT+01:00 Pavel Grunt <pgrunt@xxxxxxxxxx>:On Thu, 2017-03-09 at 06:43 -0500, Frediano Ziglio wrote:

Since you are on el7 system you can test our nightly builds:
https://copr.fedorainfracloud.org/coprs/g/spice/nightly/
which provides ability to switch the video encoder in spicy (package
spice-gtk-tools) under Options menu.
Your vm needs to have the video streaming enabled (set to 'filter' or
'all').
(virsh edit VM ; and add <streaming mode='all'/> to graphics node)
Also check if the image compression is turned on (ideally set to glz)
