One more thing. When I close the video, the CPU usage by qemu reduces to 6 % or lesser.

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:

The top command output is showing the following on the node:

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

Thank You
