I'm wondering if kvm supports automatic memory ballooning. I've had a kvm

could manually change the amount of ram it had allocated in the console,

Is there any support for that?
That would be part of a management application. qemu only knows about
the guest it controls, while ballooning needs a global view of the system.
All a single guest needs to do is only use as much ram as it needs at any
given time (up to the max allocated). So if the guest hasn't used much ram in
a given time frame, "free" the free ram from the host, and only reallocate
when needed. It doesn't _need_ a management application, just happens to be
the way people do it.
Well, for a single guest you are correct, but this is better solved
generically for multiple guests.
