Virtual machine allocation resources management program, virtual machine allocation resource management device and the virtual machine allocation resource management method

摘要

PROBLEM TO BE SOLVED: To optimize allocation of a physical memory in a virtual machine.;SOLUTION: A physical resource usage rate calculation unit 103 calculates a percentage for each virtual machine by dividing an amount used actually with virtual machines 121-1 to 121-n by an allocation amount of a physical resource 112 allocated to the virtual machines 121-1 to 121-n by a virtual machine management unit 111. A physical resource allocation amount increase/decrease unit 104 compares a usage rate of the physical resource 112 for each virtual machine calculated by the physical resource usage rate calculation unit 103 with a comparison threshold read from a setting file 106. Then, a physical resource allocation amount increase/decrease unit 104 increases or decreases the allocation amount of the physical resource 112 to a corresponding virtual machine by an increase/decrease unit read from the setting file 106, depending on the result of comparison between the usage rate of the physical resource 112 and the comparison threshold.;COPYRIGHT: (C)2011,JPO&INPIT
