IN-PLACE RECOVERY OF FATAL SYSTEM ERRORS AT VIRTUALIZATION HOSTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240338282 titled 'IN-PLACE RECOVERY OF FATAL SYSTEM ERRORS AT VIRTUALIZATION HOSTS

Simplified Explanation: The patent application describes a method for recovering fatal system errors in virtualization hosts without disrupting the operation of virtual machines.

• The device identifies a fatal system error in the host operating system.
• It decides to perform an in-place recovery for the error.
• The recovery process involves pausing the execution of the affected virtual machine, preserving its state in system memory, and then resuming its operation with a second instance of the host OS.

Key Features and Innovation:

• Identification of fatal system errors in virtualization hosts.
• In-place recovery process without disrupting virtual machine operation.
• Preservation of virtual machine state in system memory.
• Seamless transition to a second instance of the host OS for continued operation.

Potential Applications: This technology can be applied in data centers, cloud computing environments, and any system utilizing virtualization technology.

Problems Solved:

• Minimizing downtime due to fatal system errors.
• Ensuring continuous operation of virtual machines.
• Streamlining the recovery process in virtualization hosts.

Benefits:

• Improved system reliability.
• Enhanced fault tolerance.
• Reduced impact of fatal errors on virtual machine performance.

Commercial Applications: Potential commercial applications include data center management software, cloud service providers, and virtualization solution providers.

Prior Art: Readers can explore prior art related to in-place recovery methods for fatal system errors in virtualization hosts in academic journals, patent databases, and industry publications.

Frequently Updated Research: Stay informed about the latest advancements in virtualization technology, system recovery methods, and fault tolerance strategies to enhance the effectiveness of this innovation.

Questions about Virtualization Host Recovery: 1. How does the in-place recovery process impact the overall performance of virtual machines? 2. What are the potential challenges in implementing this technology in large-scale virtualized environments?

Original Abstract Submitted

in-place recovery of fatal system errors at virtualization hosts. a device identifies an occurrence of a fatal system error in the first instance of a host operating system (os) executing in a computer system. the device determines to perform an in-place recovery for the fatal system error. the device performs the in-place recovery, including pausing the execution of a virtual machine (vm) by the first instance of the host os, preserving a state of the vm within system memory of the computer system, and resuming the execution of the vm by a second instance of the host os executing in the computer system based on the state of the vm that is preserved within the system memory of the computer system.
