متن کاملOperating System Fingerprinting for Virtual Machines
In computer security field, Operating System fingerprinting (OSF) is the process of identifying the OS variant and version. OSF is considered an important stage to decide security policy enforced on protected Virtual Machine (VM). OSF is also the first step of VM introspection process. Unfortunately, current OSF techniques suffer many problems, such as: they fail badly against modern Operating ...
متن کاملOperating System Support for Virtual Machines
A virtual-machine monitor (VMM) is a useful technique for adding functionality below existing operating system and application software. One class of VMMs (called Type II VMMs) builds on the abstractions provided by a host operating system. Type II VMMs are elegant and convenient, but their performance is currently an order of magnitude slower than that achieved when running outside a virtual m...
متن کاملA Virtual Memory Operating System for a Distributed Workstation Environment
Recently we have seen an explosive growth in the number of high performance, low cost workstations available on the market. An increase in the usage and popularHy of new applications like windowing systems and object oriented applications has resulted from this growth. These applications rely heavily on data sharing. To support these applications, the operating system must support efficient sha...
متن کاملXtreemOS: Towards a Grid Operating System with Virtual Organisation Support
XtreemOS is a European project which aims to develop an open source Grid operating system based on the existing Linux operating system. A key goal of XtreemOS is the native support for Virtual Organisations. In this poster, we present the overall motivations, aims and components of XtreemOS and give an initial view of the support for Virtual Organisations.
