SOFTWARE SAFE SHUTDOWN SYSTEM, SOFTWARE SAFE SHUTDOWN METHOD, AND PROGRAM

摘要

Provided is a software safe shutdown system, comprising: an OS anomalous shutdown detection unit, which detects that an operating system of a virtual machine which is executed by a computer system has had an anomalous shutdown due to a memory leak; a memory resource securing unit which secures, from among a usable memory resource within the computer system, a memory resource which is necessary to recover a console function of the anomalously shutdown virtual machine; and a console acquisition unit which allocates the secured memory resource to the anomalously shutdown virtual machine, and which, after recovering the console function, normally shuts down the virtual machine using the console function.

1. A software safe shutdown system, comprising:
an OS anomalous shutdown detection unit configured to detect that an operating system of a virtual machine, which is executed by a computer system, has had an anomalous shutdown due to a memory leak; a memory resource securing unit configured to secure a memory resource required for recovering a console function of the anomalously shutdown virtual machine from within a memory resource available in the computer system; and a console acquisition unit configured to allocate the secured memory resource to the anomalously shutdown virtual machine and, after the console function has been recovered, normally shut down the virtual machine by using the console function.
