| Research Abstract |
The goal of this particular research is to improve availability of computer systems under operating system kernel failures. This research focuses on a software mechanism of quickly recovering from kernel failures. This approach offers several benefits such as improving service availability, reducing maintenance costs of physical hosts, reducing power-consumption. The research outcomes are as follows; 1.) A mechanism to quickly recover from kernel failures are designed and implemented. 2.) The mechanism reduces downtime for a conventional OS recovery method by at most 90%. 3.) Solid-State Drives can accelerate execution of the proposed mechanism，an extension enables the mechanism to shorten downtime caused by software update, leveraging Graphic Processing Units(GPUs) accelerates virtual machine live migration, which move a virtual machine to another physical host without any data loss, due to their parallel processing feature.
