PROBLEM TO BE SOLVED: To shorten a time until restarting processing after migration.SOLUTION: When processing being executed in a second VM host is to be interrupted and executed in a first VM host, the first VM host calculates a first time required for transferring data stored in a storage area of the second VM host to the first VM host until interrupting the processing. The first VM host calculates a second time from a transfer time which is required for transferring data to be used when executing the interrupted processing from the beginning from an area where the data are stored to the first VM host and the processing time required for interrupting the processing. In the case where the first time is earlier than the second time, the first VM host restarts the interrupted processing from a time point of interruption, and in the case where the second time is earlier than the first time, the first VM host restarts the interrupted processing from the beginning. |
