Non-transitory computer-readable storage medium, live migration method, and live migration apparatus

A live migration method executed by a computer, the live migration method comprising:

• starting live migration of a virtual machine to another computer in response to reception of an instruction of the live migration of the virtual machine, an emulator which becomes a substitute for hardware capable of dynamically defining a function is implemented in the virtual machine;
• causing the emulator to execute a requested process requested from the virtual machine to the hardware when a degree of progress taken to transmit data of the live migration of the virtual machine satisfies a first condition;
• and
• switching the computer executing the virtual machine to the other computer when the degree of progress satisfies a second condition to determine whether the computer executing the virtual machine is switched and when the hardware is not executing a process of the virtual machine.

A live migration apparatus comprising:

• a memory;
• and
• a processor coupled to the memory and the processor configured to:
• start live migration of a virtual machine to another computer in response to reception of an instruction of the live migration of the virtual machine, an emulator which becomes a substitute for hardware capable of dynamically defining a function is implemented in the virtual machine;
• cause the emulator to execute a requested process requested from the virtual machine to the hardware when a degree of progress taken to transmit data of the live migration of the virtual machine satisfies a first condition;
• and
• switch the computer executing the virtual machine to the other computer when the degree of progress satisfies a second condition to determine whether the computer executing the virtual machine is switched and when the hardware is not executing a process of the virtual machine.
