Virtual Machine Technologies and Their Application in the Delivery of ICT
Virtual Machine Technologies and Their Application In The Delivery Of ICT William McEwan accq.ac.nz n Christchurch Polytechnic Institute of Technology Christchurch, New Zealand [email protected] ABSTRACT related areas - a virtual machine or network of virtual machines can be specially configured, allowing an Virtual Machine (VM) technology was first ordinary user supervisor rights, and it can be tested implemented and developed by IBM to destruction without any adverse effect on the corporation in the early 1960's as a underlying host system. mechanism for providing multi-user facilities This paper hopes to also illustrate how VM in a secure mainframe computing configurations can greatly reduce our dependency on environment. In recent years the power of special purpose, complex, and expensive laboratory personal computers has resulted in renewed setups. It also suggests the important additional role interest in the technology. This paper begins that VM and VNL is likely to play in offering hands-on by describing the development of VM.

Introduction to Virtualization Virtualization
Introduction to Virtualization Prashant Shenoy Computer Science CS691D: Hot-OS Lecture 2, page 1 Virtualization • Virtualization: extend or replace an existing interface to mimic the behavior of another system. – Introduced in 1970s: run legacy software on newer mainframe hardware • Handle platform diversity by running apps in VMs – Portability and flexibility Computer Science CS691D: Hot-OS Lecture 2, page 2 Types of Interfaces • Different types of interfaces – Assembly instructions – System calls – APIs • Depending on what is replaced /mimiced, we obtain different forms of virtualization Computer Science CS691D: Hot-OS Lecture 2, page 3 Types of Virtualization • Emulation – VM emulates/simulates complete hardware – Unmodified guest OS for a different PC can be run • Bochs, VirtualPC for Mac, QEMU • Full/native Virtualization – VM simulates “enough” hardware to allow an unmodified guest OS to be run in isolation • Same hardware CPU – IBM VM family, VMWare Workstation, Parallels,… Computer Science CS691D: Hot-OS Lecture 2, page 4 Types of virtualization • Para-virtualization – VM does not simulate hardware – Use special API that a modified guest OS must use – Hypercalls trapped by the Hypervisor and serviced – Xen, VMWare ESX Server • OS-level virtualization – OS allows multiple secure virtual servers to be run – Guest OS is the same as the host OS, but appears isolated • apps see an isolated OS – Solaris Containers, BSD Jails, Linux Vserver • Application level virtualization – Application is gives its own copy of components that are not shared • (E.g., own registry files, global objects) - VE prevents conflicts – JVM Computer Science CS691D: Hot-OS Lecture 2, page 5 Examples • Application-level virtualization: “process virtual machine” • VMM /hypervisor Computer Science CS691D: Hot-OS Lecture 2, page 6 The Architecture of Virtual Machines J Smith and R. -

It includes making a single physical resource (such as a server, an operating system, or storage device) appears to function as multiple logical resources. Miguel Vidal, Jos´eCastro The Art of Virtualization with Free Software What is Virtualization Types of Virtualization Definitions Virtualization is a methodology of dividing the resources of a computer into multiple execution environments. Virtualization applies one or more concepts or technologies such as partitioning, time-sharing, partial or complete machine simulation, emulation, quality of service, and many others. Colloquially, virtualization refers to the abstraction of computer resources. Miguel Vidal, Jos´eCastro The Art of Virtualization with Free Software What is Virtualization Types of Virtualization Hypervisors In modern computing, Virtual Machine Monitors (aka hypervisors) allow many different OS, tasks and software configurations exist on the same physical machine. -
