Mechanism for Optimizing Initial Placement of Virtual Machines to Reduce Memory Consumption Based on Similar Characteristics

A system, comprising:

• a memory;
• a processor communicably coupled to the memory;
• and
• a virtual machine (VM) placement agent executed from the memory and the processor, the VM placement agent configured to:
• identify characteristics of a new VM to be placed by the VM placement agent on one of a plurality of candidate host machines;
• for each candidate host machine of the plurality of candidate host machines, communicate with one or more VM agents that are each associated with a VM of one or more VMs hosted by the candidate host machine in order to identify characteristics of the one or more VMs;
• and
• identify the candidate host with the most VMs having similar characteristics to the new VM.

An article of manufacture comprising a machine-readable storage medium including data that, when accessed by a machine, cause the machine to perform operations comprising:

• identifying characteristics of a new virtual machine (VM) to be placed by a host controller on one of a plurality of candidate host machines;
• for each candidate host machine of the plurality of candidate host machines, communicating with one or more VM agents each associated with a VM of one or more VMs hosted by the candidate host machine to identify characteristics of the one or more VMs;
• and
• identifying the candidate host with the most VMs having similar characteristics to the new VM.
