1. A method of operating a resource management node comprising: identifying an unproductive group of guest virtual machines (VMs) that satisfy a defined rule for being unproductive on an first group of physical host machines based on infrastructure of a distributed computing system used by the first group of the physical host machines to host the guest VMs; generating a relocation scenario for relocating the unproductive group of the guest VMs from first group of the physical host machines to a second group of physical host machines; estimating an effect of the relocation scenario on infrastructure usage of the distributed computing system; and relocating the unproductive group of the guest VMs from the first group of the physical host machines to the second group of the physical host machines based on the relocation scenario.
