Hypervisor

Virtualization is a combination of software and hardware engineering that creates Virtual Machines (VMs) - an abstraction of the computer hardware that allows a single machine to act as if it were many machines, or a computer that does not physically exist as a piece of hardware. The hardware that is seen by the operating system is emulated in an effort to separate the physical hardware from operating system. This allows the virtual machine to be moved and hosted on any machine independent of hardware

You are a Windows 7 administrator at Contoso, a very large and international pharmaceutical company. You have 25 servers in your network running a combination of Windows Server 2000, Server 2003, SuSe Linux. As your Chief Information Officer is brainstorming with you and his/her staff, you mention that you have heard about Virtualization and it may be a very cost effective and efficient way to upgrade everything to Windows Server 2008. Your boss tells you to research the concepts and to get back

instruct a guest operating system, data storage, or network device to use underlying shared hardware or software as described by Pearce et al. [1]. Abstraction is managed at a software layer known as a virtual machine monitor (VMM) or hypervisor. The VMM or hypervisor emulates hardware to guest operating systems and applications, which includes core processor unit (CPU), memory, input/output (I/O), and network traffic [1, pp.2]. There are different areas of virtualization, which include server virtualization

the network traffic flowing within the virtual environment, which makes it difficult to detect Malicious “insider” Activity and Attacks. In the event that an internal malicious user or an attacker manages to compromise the virtualization layer, or hypervisor, this could lead to a compromise of all servers hosted on this virtual environment and as a result all applications and data residing in it.” If one’s definition of a secure virtual environment conflicts with prevailing standard definitions,

assume a trusted monitoring application, then a trusted kernel, to solutions adding the enforcement into an administrative virtual machine. They have further evolved by proposing solutions in which only the hypervisor is trusted to, finally,solutions that protect the (untrusted) hypervisor from lower levels. In parallel, technologies for root-of-trust have evolved to cope with these new protection needs. Virtualization enables the software emulation of the physical properties of a physical

virtual machine. VMware software provides a complete set of virtualized hardware to the guest operating system. VMware desktop software runs on Microsoft Windows, Linux, and Mac OS X, while its enterprise software hypervisors for servers, VMware ESX and VMware ESXi, are bare-metal hypervisors that run directly on server hardware. The suite of products from VMware includes virtualization platforms to run virtual machines along with migration and conversion tools, assessment tools, and management tools

Linux Assignment 2015 Evaluation of Linux Containers What is a Linux Container? The Linux Containers (LXC) feature is a lightweight virtualization mechanism that does not require you to set up a virtual machine on an emulation of physical hardware. (Oracle, 2015) Linux-based containers are emerging cloud technologies based on fast and lightweight process virtualization. It offers users an environment near identical performance to a standard Linux distribution, as opposed to para-virtualization

Cloud computing has become one of the most popular computing paradigms. Today, the number of cybercrimes against cloud computing is increased where attackers using new techniques and method that make the process of tracking them difficult. This makes digital investigators and practitioners to think about designing and developing new techniques and tools to cope with the cybercrimes investigation in the cloud environment. Digital forensics strategies, methodologies, and techniques have to evolve to

Server Virtualization Abstract: During past thirty years, the term concept of server virtualization has invoked in order to allow the large expensive main frame servers to be used and shared among the different application layered environments from various geographical locations. “Server Virtualization is a process of portioning the single main server into several server partitions”. In clear terms to state, main server is being used as many number of cloned severs where maximum programmers/users

Virtualization Security in Data Centers and Clouds Minjie Zheng, mzheng@go.wustl.edu (A project report written under the guidance of Prof. Raj Jain) DownloadPDF Abstract In the past decade, with the unprecedented growth in tech companies and advances in cloud computing, it has become increasingly common for companies to incorporate virtualization in their data centers to fully utilize their hardware resources. As a result, virtualization and virtualization security have gone through major transforms
