The Server Virtualization Landscape, Circa 2007
ghaff@ illuminata.com Copyright © 2007 Illuminata, Inc. single user license Gordon R Haff Illuminata, Inc. TM The Server Virtualization Bazaar, Circa 2007 Inspired by both industry hype and legitimate customer excitement, many Research Note companies seem to have taken to using the “virtualization” moniker more as the hip phrase of the moment than as something that’s supposed to convey actual meaning. Think of it as “eCommerce” or “Internet-enabled” for the Noughts. The din is loud. It doesn’t help matters that virtualization, in the broad sense of “remapping physical resources to more useful logical ones,” spans a huge swath of Gordon Haff technologies—including some that are so baked-in that most people don’t even 27 July 2007 think of them as virtualization any longer. Personally licensed to Gordon R Haff of Illuminata, Inc. for your personal education and individual work functions. Providing its contents to external parties, including by quotation, violates our copyright and is expressly forbidden. However, one particular group of approaches is capturing an outsized share of the limelight today. That would, of course, be what’s commonly referred to as “server virtualization.” Although server virtualization is in the minds of many inextricably tied to the name of one company—VMware—there are many companies in this space. Their offerings include not only products that let multiple virtual machines (VMs) coexist on a single physical server, but also related approaches such as operating system (OS) virtualization or containers. In the pages that follow, I offer a guide to today’s server virtualization bazaar— which at first glance can perhaps seem just a dreadfully confusing jumble. -

Porting the QEMU Virtualization Software to MINIX 3
Porting the QEMU virtualization software to MINIX 3 Master's thesis in Computer Science Erik van der Kouwe Student number 1397273 [email protected] Vrije Universiteit Amsterdam Faculty of Sciences Department of Mathematics and Computer Science Supervised by dr. Andrew S. Tanenbaum Second reader: dr. Herbert Bos 12 August 2009 Abstract The MINIX 3 operating system aims to make computers more reliable and more secure by keeping privileged code small and simple. Unfortunately, at the moment only few major programs have been ported to MINIX. In particular, no virtualization software is available. By isolating software environments from each other, virtualization aids in software development and provides an additional way to achieve reliability and security. It is unclear whether virtualization software can run efficiently within the constraints of MINIX' microkernel design. To determine whether MINIX is capable of running virtualization software, I have ported QEMU to it. QEMU provides full system virtualization, aiming in particular at portability and speed. I find that QEMU can be ported to MINIX, but that this requires a number of changes to be made to both programs. Allowing QEMU to run mainly involves adding standardized POSIX functions that were previously missing in MINIX. These additions do not conflict with MINIX' design principles and their availability makes porting other software easier. A list of recommendations is provided that could further simplify porting software to MINIX. Besides just porting QEMU, I also investigate what performance bottlenecks it experiences on MINIX. Several areas are found where MINIX does not perform as well as Linux. The causes for these differences are investigated. -

Crossover Compared to Competing Emulation Solutions
CrossOver Compared to Competing Emulation Solutions CrossOver Compared to Competing Emulation Solutions CrossOver Compared to Competing Emulation Solutions Overview: Whether you’re running a Linux or Mac OS X machine, chances are you need a way to run at least some Windows applications or games that aren’t available on your platform of choice. And you have your choice of potential solutions to this problem. This page illustrates some of the key Every Windows advantages that CrossOver has in relation to the compatibility solution has other compatibility solutions. pros and cons. When presented with the need to run Windows applications on a Mac or Linux machine, you have basically three main choices: Dual-booting: running two separate operating systems on one PC, and switching between them as needed by rebooting. Applications such as Apple’s Bootcamp allow this to occur on a Mac OS X machine, for example. Running a virtual machine: Emulation products such as VMWare and Parallels allow you to install a copy of Windows within a logical partition within your native operating system. The Windows applications essentially run in a separate “box within a box.” Running Wine or CrossOver: Unlike emulation, Wine is a re-implementation of the Win32 API, allowing applications to run as if natively on the target OS. CrossOver is a commercialized version of Wine. Each solution has its advantages and disadvantages. This document is provided to help identify and evaluate key points of comparison between CodeWeavers’ CrossOver products and some of its key competitors. Technology Approach General Approach Dual-booting is exactly what it sounds like—shutting down one operating system, starting another, and dealing with the file transfer issues associated with same.
