Memory Balloon This counter reflects the total amount of memory the VMkernel is
effectively “borrowing” from virtual machines via the VMTools balloon driver running
inside the guest OS. Balloon driver activity indicates over-commitment of ESX host
memory. By default, the VMkernel may balloon up to 65% of a virtual machines
configure RAM.
