Not locally, the guest run in server A.
I remote control the guest from my laptop.

I'm sorry that I misled you.
The guest OS is windows 7 so that I cannot use virgl.
I got the configuration from libvirt.org <http://libvirt.org> and I
don't know which configuration will work for me, so I pasted all in the
mail.
Do you mean the default configuration the best suited for my case?
If you run your VM "locally" (the server and the client
are running on the same machine) you probably do not gain
from image-compression/video-streaming.

How can I change the configuration for the compression ?
I want to play 720p video smoothly in the guest(some loss or
distortion
does not matter).
What is the best configuration for me?
I got that I can change option of graphics in libvirt like:
<graphics type='spice' port='-1' tlsPort='-1' autoport='yes'>
<channel name='main' mode='secure'/>
<channel name='record' mode='insecure'/>
<image compression='auto_glz'/>
<streaming mode='filter'/>
<clipboard copypaste='no'/>
<mouse mode='client'/>
<filetransfer enable='no'/>
<gl enable='yes'
rendernode='/dev/dri/by-path/pci-0000:00:02.0-render'/>
</graphics>
Which option should I change ?
Can I also customize more parameter about the vga(such as fps,
bitrate
...) ?

Hi John,
What is the guest OS?
According to your configuration above, I assume you are
running the VM locally on your workstation.
Also I see you are trying to use virgl (gl enable=yes)
If this is the case, for Linux guests, you need not to worry about
image/video compression.
Just make sure you are using virtio-vga and that the
given 'rendernode' is correct and accessible,
and that you have new enough qemu-kvm/spice-server and
remote-viewer or virt-manager.
Regards,
Uri.
