VIRTUAL MACHINE PLACEMENT METHOD USING SCHEDULING AND VIRTUAL MACHINE PLACEMENT DEVICE IMPLEMENTING THE SAME

摘要

A virtual machine placement method according to an embodiment of the present invention includes a physical server on which a virtual machine is installed, wherein the physical server includes a first physical server and a second physical server. In order to operate efficiently, a method of deploying a plurality of the virtual machines on the first physical server and the second physical server, wherein the first physical server and the second physical server Calculating virtual machine workload information that is information related to a virtual machine workload that is a load of a physical server charged by the virtual machine by a predetermined workload calculation method based on information related to operation; Calculating initial predictive virtual load information that is information related to an initial predictive virtual load associated with a load of a physical server charged by the virtual machine predicted for a predetermined first period based on the virtual machine workload; Calculating batch schedule information that is information related to the batch schedule of the virtual machines on the first physical server and the second physical server by a predetermined batch schedule calculation method; And the virtual machine is disposed on the first physical server and the second physical server according to the arrangement schedule calculated by the predetermined arrangement schedule calculation method. Including the step of being moved while moving on the physical server, The predetermined batch schedule calculation method is a method for calculating the batch schedule of the virtual machine when the objective function value is minimized based on the initial predicted virtual load information. Can be
