Analysis Of Xen And The Art Of Virtualization - 1028 Words

Xen and the Art of Virtualization† Paul Barhamâˆâ€", Boris Dragovic, Keir Fraser, Steven Hand, Tim Harris, Alex Ho, Rolf Neugebauer, Ian Pratt, Andrew Warfield describes the concept of a Virtual Machine and implementation of a new x86 virtual machine monitor called Xen. However, existing virtualization techniques came with large performance overhead or other limitations such as decreased level of security. Some modern day processors require specialized hardware or cannot support commodity operating system or others sacrifice security or functionality for speed while some offer performance guarantees. So in totally there is no such virtual machine that reaches a middle ground between full virtualization and containers. Why is this problem Important? Virtualization is a way to give users flexibility of running whatever they want in their own machine, while it is actually running on a single physical machine among others. Since the power of modern processors are increasing day by day it is important that machine is better utilized for example if multiple users can share machine. Moreover, if we look at modern day processors, every processor compromises one or the other functionality to build a particular set. So, it is very important to make a new revolution in the field of virtualization technology such that a common point is met between performance, hardware, security and speed.

In closing the Multics discussion, we note that a number of Multics security mechanisms, state-of-the-art at the time, remain prevalent today even though they do not work as well for modern computing environments. These mechanisms include access control lists (ACLs), machine-generated passwords, and weak encryption of the password ï ¬ le [33, 39].
