Relatedly Jane Walker writes "SearchOpenSource has two authors that try to show why VMware ESX Server is miles ahead of Xen and Virtual Server. Discover what to watch out for when running ESX Server and how to avoid sprawl in your virtual data center."

Ravi writes "There is commercial grade software like VMware (which does full virtualization) as opposed to open source approaches like Xen which do partial virtualization. But besides these two, there is a very interesting piece of software called User Mode Linux (UML), which can be used to create virtual Linux machines within a Linux computer. Unique to UML is that support for it has been incorporated into the mainstream Linux kernel tree and it is now a fully supported part of the official Linux kernel. On this note, UML gains a lot of significance. UML has been created and maintained by Jeff Dike, who is known throughout the Linux technical community. And when someone who has created a popular software decides to author a book on the subject, then that book is sure to hold a lot of promise. So when I came across the book titled User Mode Linux, authored by Dike under Bruce Perens' Open Source Series, I just couldn't resist getting my hands on it." Read on for the rest of Ravi's review.

^switch writes "Aussies at NICTA have developed a para-virtualized Linux called Wombat that they claim outperforms native Linux. From the article: 'The L4 Microkernel works with its own open source operating system Iguana, which is specifically designed as a base for use in embedded systems.'" Specific performance results are also available from the NICTA website.

Carl Bialik from WSJ writes "Why did Microsoft make the surprise announcement that it would support business customers who also use Linux? Because of the increasing importance of virtualization, Lee Gomes writes in the Wall Street Journal. 'Once businesses start using virtualization to cut back on the number of machines they need to buy, "a light bulb goes on over their head," says Tony Iams, who follows the field for Ideas International, an analyst group,' Gomes writes. 'Other uses become apparent, such as backing up data or easily adding processor power to a particular application as the need arises.' VMware pioneered the market, but now Microsoft is 'expected to offer sophisticated virtualization products in the next year or two,' Gomes writes. 'The company currently has a fairly rudimentary product, which was involved in its big Linux announcement earlier this month.'"

VirtualizationBuff writes "KernelTrap has a fascinating interview with Andrey Savochkin, the lead developer of the OpenVZ server virtualization project. In the interview Savochkin goes into great detail about how virtualization works, and why OpenVZ outshines the competition, comparing it to VServer, Xen and User Mode Linux. Regarding virtualization, Savochkin describes it as the next big step, 'comparable with the step between single-user and multi-user systems.' Savochkin is now focused on getting OpenVZ merged into the mainline Linux kernel."

Jane Walker writes to tell us that TechTarget has a short writeup on virtualization and some of the ins and outs of using this technology effectively. From the article: "Virtualization is a hot topic in the enterprise space these days. It's being touted as the solution to every problem from server proliferation to CPU underutilization to application isolation. While the technology does indeed have many benefits, it's not without drawbacks."

liliafan writes "In an effort to gain a market majority over VMware Microsoft announced it is giving Virtual Server away for free, additionally they will provide customer support for Linux. In a related move VMware have opened their partition file format to the community, aggressive and suprising moves in the virtualisation market."

OSS_ilation writes "IT troubleshooting firm Splunk is using LinuxWorld Boston as a platform to formally launch Splunk Base, a global wiki that will offer IT pros a free-of-charge venue to exchange troubleshooting information, tools and fixes. Splunk is promising that the wiki is completely vendor neutral, and can be compared to Wikipedia, the online open encyclopedia that is regulated and updated by the community-at-large. Users don't even have to have a copy of Splunk Professional to use it. From the article: 'If you believe the research from firms like Framingham, Mass.-based IDC, then Splunk Base has arrived at a key moment. According to IDC, companies will spend more than $100 billion this year on managing the world's data centers. And with virtualization quickly becoming an IT buzzword in 2006, the complexity and costs could increase.'"

LinuxWorld Boston is fast approaching and this year there will be an "official" blog that follows some of the events, posted right here as a Slashdot Journal. There are several interesting talks lined up and even a Slashdot lounge where you can take a break from the busy convention floor and give us a chance to meet our readers -- Read on for the LWCE blog outline of the event.

Anonymous Coward writes to tell us eWeek is reporting that Novell is currently working on a new suite of tools that will assist in the management of data centers across Windows, Unix, and Linux environments. From the article: "The tools also help users maximize server utilization by setting up a series of workload policies based on the business application resources required. The project, currently titled "The policy-driven adaptive data center," will leverage virtualization, identity management and resource management to deliver a flexible and adaptive data center."

OSS_ilation writes "Red Hat was all about virtualization in a recent announcement for an 'integrated virtualization' initiative with XenSource and chipmakers AMD and Intel. The move was seen as a way for Red Hat to bring its commitment to virtualization technology into 'sharper focus [...] with the release of a product roadmap that includes virtualization technology built into its enterprise version of Linux.' Red Hat's CTO, Brian Stevens, said the move would remove the complex 'rocket science' aspect of virtualization, and drive the technology into more enterprises as a result."

Steve Wilson writes "Cassatt Corporation has released new software that enables administrators with large J2EE farms to much more efficiently use their resources. In order to do this, it leverages the virtualization capabilities inherent in the JVM to create a single shared pool of hardware resources which which all J2EE applications can draw."

Drawoc Suomynona writes "The Xen virtual monitor is a new generation virtualization software that enable running multiple OSes at the same time with unprecedented level of performances. Manuel Bouyer was recently interviewed about his work porting Xen to the NetBSD operating system. The interview touches on why some consider Xen to be so good, how hard it is to integrate such a software package into an OS, and more."

Jane Walker writes "The push for a virtual data center and utility computing continued this week as Novell announced that SuSE Linux would have support for Virtual Iron out of the box." Novell has also guaranteed that 'that all existing independent software vendor (ISV) certifications will not be affected.' From the article: "'The applications certification [component] is huge,' said Novell director of data center applications Justin Steinman. 'Customers want to know that their existing applications are not going to break when they deploy their technology [on a virtual server].'"

yahyamf writes "CNET News.com is reporting that in the face of increasing competition in the OS virtualization market VMWare is going to give away its GSX server product for free, in the hope that customers who try it will eventually migrate to the more powerful ESX server. The company recently released a free VMWare Player which could only run but not create virtual machines. The company faces competition from rival products such as SWsoft's Virtuozzo, Mircrosoft's Virtual Server, as well as open source software like Xen"

RomanianClimber writes to tell us News.com is reporting that SWSoft is trying to get OpenVZ into the Linux kernel. OpenVZ is an operating system level server virtualization solution, built on Linux. From the article: "In this, it has a major ally: Red Hat, the top seller of the open-source operating system, which plans to add the software to its free Fedora version of Linux for enthusiasts. The companies' move to make OpenVZ partitioning standard in Linux is timely, said Pund-IT analyst Charles King."

Last week you submitted questions for Dr. Herb Thompson, author of the latest Microsoft-sponsored Windows vs. Linux study. Here are his answers. Please feel free to ask follow-up questions. Dr. Thompson says he'll respond to as many as he can. He's registered a new Slashdot username, FFE4, specifically to participate in this discussion. All others claiming to be him are imposters. So read, post, ask, and enjoy.

Robert wrote to mention a CBR Online article which reports that Red Hat has begun testing on Fedora Core 5. From the article: "The next version of Raleigh, North Carolina-based Red Hat's enterprise Linux distribution is not scheduled for release until the second half of 2006 but will include stateless Linux and Xen virtualization functionality and improved management capabilities. Fedora Core 5 Release 1 includes updated support for XenSource Inc's open source server virtualization software, as well as new versions of the Gnome and KDE user interfaces, and the final version of the OpenOffice.org application suite."

DIY News writes "Red Hat is aggressively pushing to get Xen virtualization technology included in the Linux kernel as quickly as possible. This move comes as Microsoft is pushing its own virtualization products and recently relaxed some of its licensing requirements around Windows Server 2003 to facilitate more pervasive adoption and use of those technologies."

rfinnvik writes "VMWare Inc. has released a new free (as in beer) virtual machine runtime called VMware Player. According to VMWare, this free VM runtime makes it possible for anyone to run virtual machines created in their Workstation, GSX or ESX products. It also runs virtual machines created in Microsoft's virtualization products. The runtime is available for both Windows and Linux."
