Design and analysis of adaptive and secured hypervisor for parallel execution of heterogeneous operating systems on a stand alone machine

Abstract

Virtualization Technology has witnessed phenomenal growth in educational institutions, business organizations and IT sectors in recent years. This technology provides capital cost minimization, efficient operating expenses, IT services, resource management, flexibility, partition/aggregation of resource, and mobility. Intel and AMD organizations have developed virtualization to extend the hardware resources in x86 architectures. Utilization of existing resources to execute on more than one heterogeneous operating system simultaneously in a single machine, without rebooting the machine, is of research interest to various academicians and research groups. It is actually possible to run more than one dissimilar operating systems in the desktop or laptop without restarting using hypervisor. A structured approach identifies a systemic solution to the above cited problem of design and development of a hypervisor, capable of enabling the same. The literature of virtualization research gamut is analysed and pragmatic knowledge is acquired. The literature review provides an insight to the previous works and the scope of research being carried out by various authors and research groups in the design and development of hypervisors. Irrespective of the type of architecture in constructing the virtual machine, features such as scalability, reliability, vulnerability, resource utilization are a few parameters investigated in the developed virtual machines. Among the various techniques in the design of virtualization, hardware virtualization technique was found to be the most prevalent method for designing a hypervisor. It is proposed to design a new hypervisor using hardware virtualization techniques for implementing the virtual machines in a stand-alone environment. The scope is to make it easy to handle data without any changes to all running cross-platform operating systems, making it easy to switch from any running operating system to another, and to make it easy for all running operating systems to communicate with the internal and external network. The problem has been identified that any Intel/AMD based architecture machine is not running in multiple operating systems simultaneously. The objective is to design an efficient hypervisor newline
