Dear all,
We are running the following setup:
ovirt-engine host:
- CentOS release 7.5.1804
- ovirt-engine-4.1.9.1-1.el7.centos.noarch
- spice-html5-0.1.7-1.el7.noarch
We have noticed problems with the Spice console. When it opens
and displays the information presented by the VM's console it
is OK at first. But as soon as any part of the display changes,
that part gets replaced by random pixelated noise.
For example I open the console of a standard CentOS server.
When I type something at the login prompt the text is invisible
and random pixels are displayed at the position of the blinking
cursor. Please see attached screenshot
spice-1-login_typing_and_cursor_waiting.png.
Please also see other the attached screenshots.
Login prompt after VM reboot: spice-2-login_after_boot.png
Login prompt after hitting Enter a few times: spice-3-login_2x_enter.png
We have tried and succesfully reproduced the issue on OSX (Chrome, FF,
Safari) and Windows (Chrome, FF).
VNC works fine.
Does it work fine with remote-viewer?
You could try different image compression too,
e.g image-compression=off

Why would this be happening? Help would be very much
appreciated.
Kind regards,
Mitja
I would also try to download a new version of spice-html5 and use
it directly to see if the problem is fixed.
Note that you can set image compression using libvirt like
<graphics type='spice' port='5901' autoport='no'>
<image compression='auto_glz'/>
</graphics>
(note the "image" element inside "graphics").

Where would I set those options?
