"Systems and Methods for Detecting System Exceptions in Guest Operating Systems" in Patent Application Approval Process

May 15, 2014



By a News Reporter-Staff News Editor at Politics & Government Week -- A patent application by the inventors CHAND, Avakash Prem (Mangalore, IN); NAGARAJ, Laxmisha (Bangalore, IN), filed on October 18, 2012, was made available online on May 1, 2014, according to news reporting originating from Washington, D.C., by VerticalNews correspondents.

This patent application is assigned to Vmware, Inc.

The following quote was obtained by the news editors from the background information supplied by the inventors: "Virtual machines, which are an abstraction of physical computing resources, may include a guest operating system that operates therein. Guest operating systems, like operating systems in non-virtualized environments, are susceptible to system exceptions, or crashes. Datacenters may include thousands, tens of thousands, or more virtual machines that are operating concurrently. Known methods for determining the status of a guest operating system include viewing the console of the virtual machine, analyzing operating system files, and executing user-space software tools within the guest operating system. Using such methods, administrators of large datacenters may be unable to continuously monitor the status of each operating system to ensure that operating systems are operating as expected. Accordingly, there is a need for improved methods and systems for detecting guest operating system crashes and reporting such crashes to administrators."

In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventors' summary information for this patent application: "Systems and methods for detecting system exceptions in guest operating systems are provided. A module is provided for each guest operating system and is capable of intercepting system exceptions within the guest operating system. The module communicates with a hypervisor to provide a current status of the guest operating system. In the event of a system exception, the module may collect system exception information, such as a memory dump.

BRIEF DESCRIPTION OF THE DRAWINGS

"FIG. 1 is an exemplary virtual infrastructure having a plurality of virtual machines and a plurality of guest operating systems.

"FIG. 2 is a swimlane diagram of an exemplary method for detecting system exceptions in the guest operating systems of FIG. 1."
