Abstract

A failover control method for a virtual computer system including a plurality of virtual computers including: monitoring a second virtual computer via a first line by a first virtual computer among the plurality of virtual computers; detecting a malfunction of the second virtual computer by the first virtual computer; receiving from the other virtual computers a notification including a monitoring result for the second virtual computer in the other virtual computers among the plurality of virtual computers by the first virtual computer; relating the monitoring result to the detected malfunction of the second virtual computer to correspond to each other; judging whether or not the correspondence between the monitoring result and the detected malfunction of the second virtual computer satisfies a predetermined condition; and giving the second computer a reset instruction via a second line, when the predetermined condition is satisfied.

Claims

1. A failover control method for a virtual computer system including a plurality of virtual computers comprising:

monitoring a second virtual computer via a first line by a first virtual computer among the plurality of virtual computers;

detecting a malfunction of the second virtual computer by the first virtual computer;

receiving from the other virtual computers a notification including a monitoring result for the second virtual computer in the other virtual computers among the plurality of virtual computers by the first virtual computer;

relating the monitoring result to the detected malfunction of the second virtual computer to correspond to each other;

judging whether or not the correspondence between the monitoring result and the detected malfunction of the second virtual computer satisfies a predetermined condition; and

giving the second computer a reset instruction via a second line, when the predetermined condition is satisfied.

2. A failover control device controlling a plurality of virtual computers via a network, comprising:

a network interface connected with the network;

a processor connected with the network; and

a memory connected with the processor, wherein;

the processor receives malfunction information relating to a communication malfunction with a first virtual computer, which is any one of the virtual computers, via the network interface;

the processor receives, from the other virtual computers, a notification including a monitoring result for the first virtual computer in the other virtual computers among the plurality of virtual computers;

the processor relates the monitoring result to the detected malfunction of the first virtual computer to correspond to each other;

the processor judge whether or not the correspondence between the monitoring result and the detected malfunction of the first virtual computer satisfies a predetermined condition; and

the processor gives the first computer a reset instruction, when the predetermined condition is satisfied.
