you can edit the definition XML for the virtual machine trough virsh:
# virsh edit $VM_NAME
and specify the image compression in the graphics xml block, mine looks
like this:
<graphics type='spice' autoport='yes' listen='::'>
<listen type='address' address='::'/>
<image compression='off'/>
</graphics>
