Recording medium having virtual machine managing program recorded therein and managing server device

Abstract

A virtual machine managing program manages plural physical machines and makes a computer device execute processing through virtual machines developed on each physical machine. Virtual machines are assigned to physical machines on the basis of CPU usage rate and temperature, and are moved among the physical machines as needed, to maintain acceptable operating conditions.

What is claimed is: 
     
         1 . A system comprising:
 a plurality of physical machines; and   a managing server configured to manage virtual machines developed on each physical machine and comprising:   a memory, and   a processor coupled to the memory and configured to:
 detect a physical event of each physical machine, 
 select a movement target physical machine from the plurality of physical machines based on a result of the detected the physical event, 
 detect calculator events of plural virtual machines developed on at least the selected movement target physical machine, 
 select a movement target virtual machine from virtual machines developed on the selected movement target physical machine based on a result of the detected calculator event, 
 select a movement destination target physical machine out of from the plurality of physical machines based on a result of the detected physical event, and 
 control a movement of the selected movement target virtual machine based on the selected movement destination target physical machine. 
   
     
     
         2 . The system according to  claim 1 , wherein the processor is configured to move and develop the selected movement target virtual machine on the selected movement destination target physical machine. 
     
     
         3 . The system according to  claim 1 , wherein the processor is configured to select a physical machine that a physical event of the physical machine is above a physical event reference level. 
     
     
         4 . The system according to  claim 1 , wherein the processor is configured to select a virtual machine which generates a highest calculator event out of the detected calculator events. 
     
     
         5 . The system according to  claim 1 , wherein the physical machine includes a control circuit configured to control a virtual machine developed on the physical machine,
 wherein the processor is configured to detect environmental temperature of the control circuit as a physical event of the physical machine.   
     
     
         6 . The system according to  claim 1 , wherein the processor is configured to detect a power consumption amount of each physical machine as a physical event of the physical machine. 
     
     
         7 . The system according to  claim 1 , wherein the physical machine includes a control circuit configured to control a virtual machine developed on the physical machine,
 wherein the processor is configured to:
 detect a usage rate of the control circuit during operation of the physical machine as the calculator event of the physical machine, and 
 detect a usage rate of the control circuit during operation of the virtual machine as the calculator event of the virtual machine. 
   
     
     
         8 . The system according to  claim 7 , wherein the processor is configured to select a virtual machine that generates a highest usage rate out of the usage rates of the control circuit associated with virtual machines developed on the movement target physical machine.
