This series doesn't have the "weight" concept, it has auto-balloon-level and
auto-balloon-granularity. The former allows you to choose which type of
kernel low-mem level you want auto-inflate to trigger. The latter allows you
to say by how much the balloon should grow (as a percentage of the guest's
current memory).
Both of them are per VM.
