Abstract—The objective of the research work is to propose an enhanced availability model for the virtual machines over hypervisor attacks. In recent years, virtualization has turned out to be a most promising area in the field of Information Technology. However, there is always security threats existing in all domains and virtualization is not new to it. Among the various components that lie in virtual environment, hypervisors have always been an ideal target for attack as they provide a single entry point into the virtual environment. Designing a model that could stand these security threats has always been a challenge. The proposed work focuses on the architecture of the virtual environment, the limitations of the various physical resources to be virtualized and addresses various security related issues. It analyses various attack vectors in a quantitative manner individually and integrates all the recovery actions to enhance the overall availability of the virtual machines.
