Ar1 issues an instruction to control the automatic operation of the master osi and an instruction to control the automatic operation of each slave 032-1 to 2-n, receives the execution results, and
The automatic operation of the slave 082-1 to 082-n and the automatic operation of the plurality of slaves 082-1 to 2-n are managed in a unified manner.

Referring to FIG. 2, the mask AOS 5 reads the automatic operation control instruction from Ar1 50° and determines whether this read instruction is an instruction to control the automatic operation of the mask OSI or the automatic operation of the slaves 052-1 to 2-n. Process 51 to determine whether the instruction is to control the mask OSI, control the automatic operation of the mask OSI

Also, slave AO56-1~ from VMM3
Processing 55 for receiving the execution results of step 6-n. Processing 56 for notifying Ar1 of the execution results received is performed.

Referring to FIG. 3, the communication mechanism 8 receives and receives automatic operation control instructions for the slave OS from the master AOS 5 and processes 80. This receiving process 81. saves the received instructions to the corresponding instruction save buffers 7-1 to 7-n. A process 82 for generating an interrupt to the slaves 032-1 to 2-n to which this saved instruction is notified, and a process 82 for the slave 032 that generated the interrupt.
-The corresponding instruction save buffer in response to the handshake command from L~2-n? - Perform processing 83.84 of notifying the instructions in 1 to 7-n to the slaves 032-1 to 2-n, and also execute the instructions notified by the handshake command from each slave AOS 6-i to 6-n. Receiving and processing the results 85. This reception performs a notification process 86 of the obtained execution result to the mask AOS 5.

Referring to FIG. 4, each slave AOS 6-1 to 6-n

Process 63 is performed to notify the VMM 3 of the execution result using a handshake command.

Next, the operation of the automatic operation method in the virtual computer system of this embodiment configured as described above will be explained.

Referring to FIG. 1 and FIG. 2, the mask AOS 5 has automatic operation of the mask OSI and a plurality of slave AOSs 6-1 to 6-1.
The instructions held by Ar1, which was created so that automatic operation of 6-n can be performed centrally, are sequentially read from the beginning (50), and instructions for controlling automatic operation of master OS 1 are read (50).
It is determined whether the instruction is to control the automatic operation of the slaves 082-1 to 2-n, for example, based on the identification code attached to each instruction (51), and if the instruction is to control the automatic operation of the master OS1, the mask The AOS 5 directly executes the instruction (52), thereby controlling the automatic operation of the mask OS 1. Then, the mask AOS5 notifies Ar1 of the execution result (53).

On the other hand, if the instruction read from Ar1 is an instruction to control automatic operation of any slave OS, mask A
The OS 5 notifies the VMM 3 of the instruction (54). The operation will be described below using an instruction to control the automatic operation of slave 032-1 as an example.

Referring to FIGS. 1 and 3, the communication mechanism 8 of the VMM 3 communicates with the slave 082-
The receiver receives the instruction for 082-1 (80) and saves it to the instruction save buffer 'l-1 corresponding to slave 082-1 (81,
), generates an interrupt to slave Δ036-1 (82
).

Referring to FIGS. 1 and 4, the slave AO 56-1 that received the interrupt issues a node shake command to the VMM 3 (60). In response to this, 7MM3 transfers the automatic driving side inl instruction in the instruction evacuation puffer 7-1 to the slave AO.
Since it is passed to S6-1 (see Figure 2 84), the slave AO
S6-1 receives this from the VMM3 (61), and then the slave AOS 6-1 controls the automatic operation of the slave 032-1 according to the received automatic operation control instruction (62). Then, the execution result is notified to the VMM3 by a handshake command (63).

Referring to FIGS. 1 and 3, the execution results issued from the slave AOS 6-1 by the handshake command are as follows:
The communication mechanism 8 of the VMM 3 accepts the request (85), and the communication mechanism 8 notifies the mask AOS 5 (86). Referring to FIG. 2, the mask AOS 5 receives the execution result from the VMM 3 (55). ), and notifies AP4 (56).

In this way, the slave ○5l- released from 8P4
According to the automatic operation control instructions in step 1, slave AO56-
1 controls the automatic operation of slave 032-1, and the execution result is returned to AP4.

Similarly, control instructions for automatic operation of other slave OSes issued from AP4 are transmitted to the corresponding slave AOS via mask AOS5 and communication mechanism 8, and the automatic operation of the corresponding slave OS is controlled. Execution results will be communicated a.
flI8. It is returned to AP4 via master Δ035.

As described above, in this embodiment, the AP4 is provided in the master OSI, which contains a mixture of instructions for controlling the automatic operation of the mask OS1 and instructions for controlling the automatic operation of the slaves 032-1 to 2-n. transmission of automatic operation control instructions from to each slave AOS, and transmission of execution results to each slave AO5
Since the automatic operation of the mask OSI and the automatic operation of a plurality of slave OSs can be centrally managed in the AP4. This makes it possible to implement various services, such as those described below, which have been difficult in the past.

(1) In 8P4 on the mask OSI, check the number of jobs on all OSes, and stop the system when the number of jobs in the system reaches 0.

(2) The AP 4 outputs the same message, such as the service end time, to the terminal owned by each OS.

〔Effect of the invention〕

As explained above, according to the present invention, an instruction for controlling automatic operation of the master OS and slave OS can be issued from the automatic operation management means on the master OS, and the execution results can be sent to the automatic operation management means described above. Therefore, automatic operation in the virtual computer system can be centrally managed by one automatic operation management means. Therefore, it becomes possible to provide various services that were previously difficult to provide.
