Re: [ovirt-users] [Spice-devel] Video performance

2017-01-25 Thread Sven Achtelik
Hi, 

where would I have to add this: 







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 ? 

http://www.jieyung.com/en/faq.asp?newsclassid=377=508

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'.
