Rejuvenation processing device, rejuvenation processing system, computer program, and data processing method

A non-transitory information storage medium storing a computer program of a rejuvenation processing device that controls a plurality of host machines in which a plurality of virtual machines operates, the program causing the rejuvenation processing device to execute:

• a host rejuvenation scheduling process of selecting a first host machine as an object to be rejuvenated from among the plurality of host machines;
• a virtual rejuvenation scheduling process of selecting at least one first virtual machine from among virtual machines operating in a second host machine which is not selected as the object to be rejuvenated from among the plurality of host machines;
• a virtual migration process of stopping the operation of the at least one first virtual machine and migrating at least one second virtual machine operating in the at least one first host machine to the second host machine;
• and
• a rejuvenation execution process of rejuvenating the at least one first host machine selected as the object to be rejuvenated after the virtual machine migration process migrates the at least one second virtual machine to the second host machine.

A data processing method of a rejuvenation processing device that controls a plurality of host machines in which a plurality of virtual machines operates, comprising:

• a host rejuvenation scheduling operation of selecting a first host machine as an object to be rejuvenated from among the plurality of host machines;
• a virtual rejuvenation scheduling operation of selecting at least one first-virtual machine from among virtual machines operating in a second-host machine which is not selected as the object to be rejuvenated from among the plurality of host machines;
• a virtual migration operation of stopping the operation of the at least one first-virtual machine and migrating at least one second virtual machine operating in the at least one first host machine to the second host machine;
• and
• a rejuvenation execution operation of rejuvenating the at least one first host machine selected as the object to be rejuvenated after the virtual machine migration process migrates the at least one second virtual machine to the second host machine.
