AugstWest asks: "I've been doing some research into what the available clustering options are for pooling CPU resources, and it looks like most of the solutions I've found require that programs be re-written to take advantage of the cluster. Since there are virtualization apps like Bochs and VMWare, where the applications just make use of a virtual CPU as if it was a real CPU, why aren't there clustering solutions that do this as well?"

Mark Brunelli, News Editor writes "Tim Witham, CTO of Open Source Development Labs and a featured speaker at LinuxWorld, says the next Linux kernel will feature improved input/output and virtualization capabilities. Said Witham: 'Enabling virtualization is a big win [for Linux 2.6] as it allows IT shops to start their development cycles for a technology they will be looking at deploying within the next year or so. There has been lots of good work done with regard to system scalability, memory management, disk I/O, process and thread scalability. Also, work done for availability, like a greatly improved multi-path I/O [were victories].'"

Nora writes "IBM developerWorks has posted an open source Slimline Open Firmware (SLOF) download intended to aid the development of operating systems and virtualization layers for PowerPC-based machines. One thing that's kind of neat about it is that it is under a pretty liberal "BSD-like" license -- something I have not often seen IBM do. If I am not much mistaken (and please correct me if I am), this license makes it compatible with both GPL'd and BSD'd projects, among others. And in the interest of full disclosure, I'd like to add that I *am* affiliated with the developerWorks site."

zaxios writes "Techworld is reporting that Microsoft has announced support for running Linux on their virtualization software, Virtual Server 2005. From the article: '[Microsoft] can't compete against VMware without support for other operating systems.' Perhaps the significance of this is that Microsoft has acknowledged Linux as an OS people might want to use, which seems an upgrade from its previous status as a communist cancer."

Roland Piquepaille writes "With recent improvements in graphic cards and in powerful Linux-based PC clusters, virtual 3D prototypes are rapidly replacing actual physical prototypes in a wide range of industries, including early adopters such as aerospace or car companies. But now, software designers are also incorporating sound and tactile feedbacks to their Virtual Reality (VR) systems for real product development. In this long article, Desktop Engineering gives several examples of these new VR developments. But even if PC clusters and off-the-shelf graphic cards are cheap, a state-of-the-art VR facility such as an immersive CAVE can still cost more than one million dollars, because you need to build the viewing facility and buy expensive projection systems. However, costs are still decreasing and virtual prototyping is reaching the mainstream stage. This overview contains selected excepts and comments."

daria42 writes "The next version of SuSE, to be shipped in mid-April, will ship with the Xen virtualization software, letting users run multiple versions of the operating system simultaneously, the company said on Thursday. The article says that Red Hat has also begun adding Xen support to Fedora."

robyannetta writes "Watch out VMware and Microsoft. Here comes Xen, an open-source virtualization for the Linux environment being pushed by Red Hat and Novell. Xen has also joined forces with leading Linux distributors, chip vendors and platform vendors to create a consortium that will more broadly enable open-source virtualization development and deployment." We've covered Xen before, but it's cool to see the momentum behind it growing, as more choice is a Good Thing.

Crow writes "IBM developerWorks has posted an interview with John McCalpin, one of the guys who works on the POWER line of processors. He discusses work on POWER5 (and how the design process works at IBM -- he's also involved in work on the POWER7) and defends the decision that IBM doesn't hand-tune their ICs (as has often been criticized on Ars Technica. Also covers some of the features in the POWER processors, like SMT, the Hypervisor and virtualization -- even addresses the question of whether AIX was designed by space aliens or not. The POWER5 just broke the 3 million transactions per minute barrier on the TPC-C benchmark."

An anonymous reader writes "The Xen team are pleased to announce the release of Xen 2.0, the open-source Virtual Machine Monitor. Xen enables you to run multiple operating systems images concurrently on the same hardware, securely partitioning the resources of the machine between them. Xen uses a technique called 'para-virtualization' to achieve very low performance overhead -- typically just a few percent relative to native. This new release provides kernel support for Linux 2.4.27/2.6.9 and NetBSD, with FreeBSD and Plan9 to follow in the next few weeks. Xen 2.0 runs on almost the entire set of modern x86 hardware supported by Linux, and is easy to 'drop-in' to an existing Linux installation. The new release has a lot more flexibility in how guest OS virtual I/O devices are configured. For example, you can configure arbitrary firewalling, bridging and routing of guest virtual network interfaces, and use copy-on-write LVM volumes or loopback files for storing guest OS disk images. Another new feature is 'live migration', which allows running OS images to be moved between nodes in a cluster without having to stop them. Visit the Xen homepage for downloads and documentation."

josh asks: "For my next project, I've decided I want to do something related to x86 virtualization (the way VMware does it or Plex86 not Xen/Bochs/etc.) but I really don't know where to start. Googling hasn't been helpful (just look at the results if you don't believe me). Are there any resources for learning about this kind of x86 virtualization? I know virtual 8086 mode wouldn't work, but without that what advantage does something like VMware have over something like Bochs? Are there any F/OSS projects aimed at something along the lines of my thinking? Please enlighten me with any references and resources you might have. Thanks!"

JamieX writes "kernelthread.com brings you a very cool and instructional article in An Introduction to Virtualization... The piece talks about the history of VM's, why they are becoming important again, implementation issues and most of all a look at a large number of virtualization solutions for all kinds of operating systems... many of them barely known... essentially more than you want to know about virtualization on a single page! Great read and reference."

An anonymous reader writes "Phoenix Technologies Ltd. unveiled a vision and roadmap for a next generation of system BIOS firmware that the company calls "core system software" today, at its Strategy 2004 conference. As defined by Phoenix, CSS is a new category of core system firmware that transcends the boundaries of traditional BIOSes and to deliver "extensible firmware that provides the critical foundation of trust, manageability, and connectivity required for networked computing," in a broad range of devices including desktop and laptop PCs, servers, and handhelds gadgets. Specific technologies that Phoenix is integrating into its d-NA CSS firmware include: support for the Trusted Computing Group (TCG) specification, remote diagnostics and error-checking, intelligent configuration checking and integrated system policy management, automated provisioning of servers and server virtualization, "radically enhanced" device power management, embedded TCP/IP, remote management functions including dynamic provisioning, load balancing and software resource control, and an XML and SOAP standards-based interface to CSS functions."

statikuz writes "Wired is reporting that IBM's new data storage system, codenamed "Storage Tank", uses software to link servers in multiple locations over an IP network, creating a sort of mega-server capable of connecting thousands of computers and processing multiple petabytes of data. 'Storage Tank has the potential to become to an organization's data what the Dewey Decimal system is to a library,' said Dan Colby, general manager of storage systems at IBM. 'It reinvents the way information is filed, managed, shared and accessed within an organization.' CERN is currently using a beta version of the system to store data from the Large Hadron Collider particle accelerator, which is being used to recreate the first moments of the Big Bang. IBM expects Storage Tank eventually will be able to handle 10 to 20 terabytes of CERN data. Get your own 'starter configuration' for only $90,000!"

Xen Team writes "The University of Cambridge Computer Laboratory Systems Research Group is pleased to announce the open source release of Xen, a virtual machine monitor for x86. Xen lets you run multiple operating system images at the same time on the same PC hardware, with unprecedented levels of performance and resource isolation. Even under the most demanding workloads the performance overhead is just a few percent --- considerably less than alternatives such as VMware Workstation and User Mode Linux. This makes Xen ideal for use in providing secure virtual hosting, or even just for running multiple OSes on a desktop machine."

uninet writes "About a month ago, NeTraverse contacted OfB Labs with an early release copy of Win4Lin 5.0, the follow-up to the already impressive Win4Lin 4.0 released in May 2002. Win4Lin, for those not familiar with it, offers near-native (or better) speed "virtualization" of a Windows box so that one can run Windows 9x (95/98/Me) inside GNU/Linux."

You asked nmap creator Fyodor many excellent questions, and his answers (below) are just as excellent. You'll want to set aside significant time to read and digest this interview, because Fyodor didn't just toss off a few words, but put some real time and energy into his answers.

HellRazr writes "From the FreeBSD hackers mailing list: 'at http://www.tel.fer.hr/zec/vimage/ you can find a set of patches against 4.8-RELEASE kernel that provide support for network stack cloning. The patched kernel allows multiple fully independent network stack instances to simultaneously coexist within a single OS kernel, providing a foundation for supporting diverse new applications.' We can sure have fun with this..."

Jules V.D. writes "CERN and IBM today announced that IBM is joining the CERN openlab for DataGrid applications to collaborate in creating a massive data-management system built on Grid computing.IBM's innovative storage virtualization and file management technology, will play a pivotal role in this collaboration, which aims to create a data file system far larger than exists today to help scientists at CERN understand some of the most fundamental questions about the nature of matter and the Universe."

Kevin P. Lawton writes "Plex86 has been completely overhauled, and simplified to be a user (application) code only Virtual Machine technology. For running user code, many of the heavy weight x86-VM techniques are unnecessary. But the bonus is, Linux can easily be made to run inside the plex86 VM, so that the kernel is actually 'pushed down' to user privilege level. This has been demonstrated on both Linux 2.4 and 2.5 kernels. Thus, Linux can run in a plex86 VM without the need for any heavy virtualization. My goal is to keep the code base trim, tight, auditable and get to usable releases quickly. And to favor those goals over adding unnecessary complexities. The first milestones have just been reached, so it's still early in development. There are email lists available on the main plex86 site."

taviso writes "Ever wondered what would happen if you could compile and run cygwin under wine ? What about compiling wine under cygwin ? well these guys have, and are planning to nest the two environments as many times as possible to see if wine can take the strain, and not without good reason: 'Having such virtualization environments run within each other is an important milestone in the lives of these projects, it is a remarkable technical feat that requires a great deal of maturity'.
