Maybe we can check if remaining memory goes up and down.
(So it could also works with qemu 1.4 as we dont have expected_downtime value)

(if remaining memory > last remaing memory){
 counter++
}

if(counter == 15){

 set_migrate_downtime = migratedowntime + 0.X sec
 counter = 0;
}

What about every 15seconds if no progress has happened? How would 
you define progress? 

I would then start at 0.15s downtime as 
default or at custom conf value if defined. If no progress happens I would double the value.
