Hi,
Hi,
I have installed ovirt engine 4.0.5 on centos 7.3. I installed
ovirt-node on a separate phyical system and added it to ovirt-engine.
I installed windows 7 in a VM on the node. I installed all the virtio
drivers in the guest. The protocol used by me to access VM is Spice
QXL. I have installed virt-viewer on the clients to access (one is
windows and othe ris ubuntu)
Now, when I pay the sample video "wildlife" in the windows the video
frame rate is very low and it is skipping a aot of frames. I tested
it on both of the clients. The screen resolution is 1280x1024 on
ubuntu and 1366x768 on windows.
The *lscpu* output of the node is:

Please suggest what should I do to improve the video performance.
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,
toso
