I believe vdsm does not create the virtio-serial port when starting the VM, so you'd have to modify this behaviour with hooks [1]. Once you do that, whenever you create a live snapshot vdsm will notify libvirt to quiesce first. Note that afaik, quiesce in qemu-ga is only supported for Linux guests. VSS quiesce support patches have been submitted, but I'm not sure what the status is there yet.
