I'm not a big fan of automatic memory management (because it's a complex thing), but why not.
I'm not sure a single qemu process can manage it easily, because it need to known if you can reclaim space from another qemu,or if host have enough memory free.

Maybe pvestatd can do it ?



My need are more manual ballonning, to add memory when a guest need it.(like "fake" memory hotplug)

I thought a bit more about ballooning in general. I we can really get stats from 
the guest, it should be possible to implement 'automatic' ballooning?
