The only reason would be that this feature could be used independently of virtio-balloon. But this would of course only be the case, if ballooning is strictly not wanted in a configuration, or the current balloon driver gets replaced by an alternative solution. I don't have any strong feelings about this, just wanted to double check. Thanks, David > > So this boils down to whether the speedup patches are merged. > > >> -- >> >> David
