Abstract

PURPOSE:To operate plural guest OSs comprehensively with an operation for real machine by conforming an interruption code to the operation in a system comprised of plural kinds of guest OSs, a virtual machine, and the real machine. CONSTITUTION:The real machine 1101 notifies an operating command inputted from a CD 1401 to the virtual machine 1201 in the interruption code. The virtual machine 1201 simulates interruption in accordance with the kind of the guest OS and the interruption code and notifies them to the guest OSs #1-#3. The guest OS executes an OS command string in accordance with the operating command registered in advance dealing with the interruption code. In this way, the comprehensive operation of a computer system when it goes down can be performed with an easy operation, which reduces the burden on an operator.

Description

Detailed Description of the Invention

[0001]

The present invention relates to a plurality of guest OSs.
It is possible to stop a virtual computer system that runs a computer with a single command or operation, and relates to optimal labor-saving technology for operation of an operator as one of the automatic operation techniques of the virtual computer system.

[0002]

2. Description of the Related Art In the prior art, as in Japanese Patent Laid-Open No. 17650/1990, an OS message and an OS command string to be executed in response to the OS message are stored in an operating procedure program on a virtual machine to automatically execute the OS. The operation execution program on the virtual machine that supports the operation executes the corresponding OS command according to the output of the designated message. In this way, one OS can be automatically operated, and the labor of the operation of the operator is reduced.

[Patent Document 1] Japanese Patent Application Laid-Open No. 1-176
The technology according to No. 50 is good in that it can automatically input a command to each OS. However, regarding irregular operations, there is no one that operates the virtual computer and the guest OS on the virtual computer with simple commands and operations.

An object of the present invention is to provide a virtual computer system capable of operating a virtual computer and a plurality of types of guest OSs on the virtual computer by a simple operation by an irregular operation such as an emergency stop. is there.

[0005]

In order to solve the above-mentioned problems, a virtual computer and a plurality of guest OSs are provided on one real computer.
In a computer system in which the virtual machine operates, the virtual machine has a function of allocating an interrupt code for the virtual machine to interrupt each virtual machine and simulating interrupts to multiple guest OSs when interrupted by the interrupt code. An interrupt code to be interrupted by the virtual machine to the guest OS is allocated for each operation instruction, and each OS has a function of executing a unique command sequence or processing when interrupted by the interrupt code.

Thus, it is possible to collectively operate a plurality of OSs on the virtual computer by one operation on the real computer.

[0007]

Before the operation is executed, the command sequence or function corresponding to the contents of the batch operation of the computer system is installed in each OS. This command string is a string of one or more OS commands corresponding to the contents of the batch operation. The above functions are
It is a program having a function of implementing the operation to be incorporated as a part of the OS when defining the configuration of S.

When a batch operation instruction command is input from the operation console of the real computer, the real computer interrupts the virtual computer with a specific interrupt code, and the virtual computer simulates an interrupt for each type of guest OS. Virtual machine
When interrupted to the guest OS, the guest OS executes the command sequence or function corresponding to the interrupt code, and all the guest OSs realize the operation of the batch operation instruction command input to the real computer.

In this way, a computer system including a plurality of OSs and virtual computers can be collectively operated by a simple operation, and a computer system in which the operation load on the operator is reduced can be provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1, 2 and 3 by taking a system stop as an example.

The real computer 1101 has a mechanism 1102 for notifying the virtual computer 1201 of an interrupt code corresponding to a predetermined operation (system stop).

1001 service processor (hereinafter SV
Abbreviated as P. ), The stop command input from the console display (abbreviated as CD hereinafter) 1401 is 100
In 1 and 1101, the interrupt corresponding to the stop command and the interrupt code are converted, and the known interrupt generation mechanism 1102
Is notified to the virtual computer 1201.

1201 has a mechanism 1202 for simulating the interrupt processing shown in FIG.

In FIG. 3, when an interrupt occurs in 3001, it is determined in 3002 whether the interrupt corresponds to the stop command. If the interrupt corresponds to the stop command, 3003 instructs OS # 1 to OS # 3 of 1301 to 1303. , A stop interrupt is notified to different types of OSs, the interrupts and interrupt codes corresponding to the types of OSs are converted, and the known mechanisms 1202 simulate the interrupts and interrupt codes for each OS. After that, in 3004, 1201 is 1301-
It waits for the completion of the processing of each OS of 1303. In 3005, it is checked whether or not the simulation processing has been performed for all guest OSs, and if there is an incomplete guest OS, the process returns to 3003. When the simulation process is completed for all guest OSs, the process returns to 3001.

On the other hand, the guest OSs 1301-1303 are
Command sequences 1511 to 1513 are generated by the interrupt shown in FIG.
It has mechanisms 1311 to 1313 for executing. Now for example
A case where a simulated interrupt enters the OS # 1 1301 will be described. OS that was waiting for an interrupt in 2001
1311 of # 1 determines the interrupt code in the determination of 2002, and in the case of the interrupt code of the stop processing, performs the processing determined by the code type in 2003. At this time, the stop processing may be incorporated in the OS when the operating environment is constructed, or may be included in the file 1511 as a command string. After completion of 2003, 1311 notifies the virtual computer 1201 by a method known in 2004 (for example, interrupt). As a result, conventionally, 1421, 1422, 1
It is not necessary to input the stop command sequence that should be input in 423, and labor can be saved.

According to this method, even when a power-off operation is performed when the OS is operated on a real computer, a mechanism for generating an interrupt to the OS by the power-off button and a mechanism for waiting for the completion of normal stop processing are provided. By incorporating it, it is possible to stop normally.

By assigning the interrupt code to an operation other than the stop, various batch operations can be performed.

[0018]

According to the present invention, a batch operation such as a normal batch stop operation of a virtual computer system capable of operating a plurality of operating systems of a plurality of types is realized by one command input from a real computer. It is possible to reduce the operational load on the operator.
