Hi,
where would I have to add this:
<graphics type='spice' autoport='yes'>
<listen type='address'/>
<image compression='off'/>
<streaming mode='filter'/>
</graphics>
I mean which file or is it somewhere in the config ?
I found something that sounds like it would do the same. What do you think
about that ?

It's written for 3.5 and does something before the VM start with a hook to
change that. Would that also work in 4.06 or is there a more elegant way to
do this ?
Thank you,
Sven

You could try enabling the streaming mode, disabled by default in el7 due
different issues (see [0])
[0] https://bugzilla.redhat.com/show_bug.cgi?id=1294564
To enable the streaming mode, you should include that inside the graphics
node, see mine bellow for an example. Options are 'off', 'all'
and 'filter'.
<graphics type='spice' autoport='yes'>
<listen type='address'/>
<image compression='off'/>
<streaming mode='filter'/>
</graphics>
Cheers,
