Placing a virtual machine on a target hypervisor

摘要

A method is provided for placing a virtual machine on a target virtual machine manager out of multiple virtual machine managers. System management software is connected to the virtual machine managers and selects the target virtual machine manager for placing the virtual machine. The method includes: the system management software creating a memory profile for all virtual machines hosted on the multiple virtual machine managers, the system management software evaluating probabilities for samepage mapping of the virtual machine to be placed on the multiple virtual machine managers based on the memory profiles of the virtual machines, the system management software selecting under consideration of the probabilities for samepage mapping a most appropriate virtual machine manager as the target virtual machine manager, and the system management software placing the virtual machine on the target virtual machine manager.

1. A method for placing a virtual machine on a target virtual machine manager out of multiple virtual machine managers, wherein a system management software is connected to the virtual machine managers and selects the target virtual machine manager for placing the virtual machine, the method comprising:
the system management software creating a memory profile for all virtual machines hosted on the multiple virtual machine managers, each memory profile being based on at least one of a static analysis of an image of the virtual machine, a dynamic analysis of the virtual machine at runtime, or an evaluation of start-up behavior of the virtual machine, evaluating probabilities for samepage mapping of the virtual machine to be placed in comparison to all virtual machines hosted on the multiple virtual machine managers based, at least in part, on the created memory profiles of the virtual machines, the evaluating including:
for an application of the memory profile of the virtual machine to be placed, searching the memory profile of another virtual machine for a matching application;for the matching found, calculating an expected efficiency gain for the virtual machine to be placed based, at least in part, on a memory consumption of the matching application;summing expected efficiency gain calculations for applications of the virtual machine to be laced to calculate the probability for samepage mapping of the virtual machine to be placed; the system management software selecting under consideration of the probabilities for samepage mapping a most appropriate virtual machine manager as the target virtual machine manager; and the system management software placing the virtual machine on the target virtual machine manager.
