[Effect]

(A) First effect Prior to automatic operation of multiple OSes, an operating procedure program for operating multiple OSes is created in consideration of synchronization points of multiple OSes. This operating procedure program is based on a message that specifies the OS to be output judged and the execution target.
The iD OS consists of a specified series of commands.

The operation execution program executes this operation procedure program as follows. First, the operation execution program determines whether the message specified in the operation procedure program has been output to the console device of the OS to be output determined. Next, in response to the message being output to the console device of the OS to be output determined, the operation execution program executes a series of commands specified in the operation procedure program to the OS to be executed.

In this way, it is possible to provide a virtual computer system that can be automatically operated while synchronizing multiple OSs.

Also, when multiple OSes work together,
It is possible to provide a virtual computer system in which multiple OSs can be automatically operated using one operating procedure program.

(B) Second Operation Prior to automatic operation of a plurality of OSs operating in synchronization, an operation control program is created that describes the synchronization points of these OSes.
