Virtualization enables your organization to attain significant gains in efficiency and cost-effectiveness, along with the additional benefits of a greener consolidated datacenter, increased scalability and improved time to resource fulfillment. Unfortunately, the advantages of virtualization

This paper describes a novel approach to providing modular and extensible operating system functionality and encapsulated environments based on a synthesis of microkernel and virtual machine concepts. We have developed a software-based virtualizable architecture called Fluke that allows recursive

Abstract Execution replay of virtual machines is a technique which has many important applications, including debugging, fault-tolerance, and security. Execution replay for single processor virtual machines is well-understood, and available commercially. With the advancement of multi

This paper describes the design and implementation of a system that uses virtual machine technology [1] to provide fast, transparent application migration. This is the first system that can migrate unmodified applications on unmodified mainstream Intel x86-based operating system, including

This paper presents the invited talk at the "Simposio Brasileiro de Arquitetura de Computadores e Processamento de Alto Desempenho (SBAC'2000)": the Virtual Virtual Machine approach for highly configurable operating systems. This is a joint work with action SOR – INRIA Rocquencourt.

Abstract. Virtual machine implementations are made up of intricately intertwined subsystems, coordinating largely through implicit dependencies. An analysis of several virtual machine implementations reveals the presence of crosscutting concerns—concerns that cannot be modularized through

loaders and demonstrate some of their interesting uses. In addition, we discuss how to maintain type safety in the presence of user-defined dynamic class loading. 1 Introduction In this paper, we investigate an important feature of the Java virtual machine: dynamic class loading. This is the underlying

This communication looks into some virtual machine implementations, from the common stack-based architecture to the newest register-based one. It evaluates the feasibility of their implementation on silicon and how this approach can improve performance while maintaining language exibility
