GJdeBoer writes "The book is aimed at people who are managing a network and would like to get insight into the performance of that network. It covers the installation and configuration of the Cacti application. In the preface the book states that it's not necessary to be a Linux Guru to use the book and that exactly is the case. The book builds up your knowledge about Cacti and the necessary steps to configure it for your network, and it teaches you about Net-SNMP and RRDTool, the building blocks of Cacti."

Dave Knott writes "After some delay Apple has updated Boot Camp to support Windows 7 on Macintosh computers. They have also provided an upgrade utility that facilitates transition to Windows 7 for Mac owners who have existing Vista installations. The new version of Boot Camp requires OS X 10.6 (Snow Leopard)."

An article at Gamasutra provides some details on the hardware Mythic uses to power Warhammer Online, courtesy of Chief Technical Officer Matt Shaw and Online Technical Director Andrew Mann. Quoting: "At any given time, approximately 2,000 servers are in operation, supporting the gameplay in WAR. Matt Shaw commented, 'What we call a server to the user, that main server is actually a cluster of a number of machines. Our Server Farm in Virginia, for example,' Mann said, 'has about 60 Dell Blade chassis running Warhammer Online — each hosting up to 16 servers. All in all, we have about 700 servers in operation at this location.' ... 'We use blade architecture heavily for Warhammer Online,' Mann noted. 'Almost every server that we deploy is a blade system. We don't use virtualization; our software is somewhat virtualized itself. We've always had the technology to run our game world across several pieces of hardware. It's application-layer clustering at a process level. Virtualization wouldn't gain us much because we already run very close to peak CPU usage on these systems.' ... The normalized server configuration — in use across all of the Mythic-managed facilities — features dual Quad-Core Intel Xeon processors running at 3 GHz with 8 GB of RAM."

Darren Ginter writes "I find many aspects of desktop virtualization compelling, with one exception: the cost of the thin clients, which typically exceeds that of a traditional box. I understand all of the benefits of desktop virtualization (and the downsides, thanks) but I'm very hung up on spending more for less. While there are some sub-$200 products out there, they all seem to cut corners (give me non-vaporware that will drive a 22" LCD at full resolution). I can PXE boot a homebrew Atom-based thin client for $130, but I'd prefer to be able to buy something assembled. Am I missing something here?"

snydeq writes "InfoWorld's Randall Kennedy takes an in-depth look at VMware Workstation 7, VirtualBox 3.1, and Parallels Desktop 4, three technologies at the heart of 'the biggest shake-up for desktop virtualization in years.' The shake-up, which sees Microsoft's once promising Virtual PC off in the Windows 7 XP Mode weeds, has put VirtualBox — among the best free open source software available for Windows — out front as a general-purpose VM, filling the void left by VMware's move to make Workstation more appealing to developers and admins. Meanwhile, Parallels finally offers a Desktop for Windows on par with its Mac product, as well as Workstation 4 Extreme, which delivers near native performance for graphics, disk, and network I/O. 'There's some genuine innovation going on, especially in the areas of hardware support and application compatibility,' Kennedy writes. 'All support 32- and 64-bit Windows and Linux hosts and guests, and all have added compelling new VM management capabilities, ranging from automated snapshots to live VM migration.'"

swsuehr writes "The Book of Xen: A Practical Guide for the System Administrator provides an excellent resource for learning about Xen virtualization. I frequently need to create test environments for examples that appear in various books and magazine articles (in the interest of full disclosure, I've never written for the publisher of this book). In the days before virtualization that meant finding and piecing together hardware. Like many readers, I've been using virtualization in one form or another for several years, including Xen. This book would've saved hours searching around the web looking for tidbits of information and sifting through what works and doesn't work in setting up Xen environments. The authors have done the sifting for me within the ~250 pages of the book. But far beyond, the authors also convey their experience with Xen using walkthroughs, tips, and recommendations for Xen in the real world." Read on for the rest of Steve's review.

laxl writes "Linux vendor Red Hat has open sourced the Simple Protocol for Independent Computing Environment (SPICE) virtual desktop protocol it acquired last year with Qumranet, which used SPICE for its own commercial desktop-virtualization product, called SolidIce. SPICE can be used to deploy virtual desktops from a server out to remote computers, such as desktop PCs and thin-client devices. It is similar to other rendering protocols used for remote desktop management such as Microsoft's Remote Desktop Protocol or Citrix's Independent Computing Architecture. SPICE supports rendering virtual instances of Windows XP and Windows 7, as well as Red Hat Enterprise Linux. According to Red Hat, SPICE has advantages over other protocols in that it can dynamically customize desktop instances to fit specific operating environments. According to the article, most of the SPICE code is available under the GNU GPLv2, though parts are also licensed under LGPL- and BSD-styled licenses."

dcblogs writes "IBM has released a new mainframe server that doesn't include its z/OS operating system. This Enterprise Linux Server line supports Red Hat or Suse. The system is packaged with mainframe management and virtualization tools. The minimum processor configuration uses two specialty mainframe processors designed for Linux. IBM wants to go after large multicore x86 Linux servers and believes the $212,000 entry price can do it."

Sharky2009 writes "VMware is developing virtualisation for smartphones which can run any two OSes — Windows Mobile, Android or Linux — at once. The idea is to have your work applications and home applications all running insider their own VMs and running at the same time so you can access any app any time. VMware says: 'We don't think dual booting will be good enough — we'll allow you to run both profiles at the same time and be able to switch between them by clicking a button,' he said. 'You'll be able to get and make calls in either profile – work or home – as they will both be live at any given point in time.'" Also mentioned in February of this year, but now the company's announced a target of 2012 for mass production.

New features include virtualization memory de-duplication, a rewrite of the writeback code faster and more scalable, many important Btrfs improvements and speedups, ATI R600/R700 3D and KMS support and other graphic improvements, a CFQ low latency mode, tracing improvements including a 'perf timechart' tool that tries to be a better bootchart, soft limits in the memory controller, support for the S+Core architecture, support for Intel Moorestown and its new firmware interface, run-time power management support, and many other improvements and new drivers. See the full changelog for more details."

Many readers are submitting stories related to Google Chrome OS. ruphus13 points out a GigaOm opinion piece about how, if users end up rejecting its current cloud-only focus, the nascent OS may succeed as a netbook secondary operating system alongside Windows (in company with secondaries based on other Linux flavors, including Android). Engadget reviews a Chrome OS on a USB key setup that is claimed to offer eye-opening performance compared to running under virtualization. And an anonymous reader notes the 0.1 beta release of ChromeShell, which installs a "Chrome OS-like" environment that boots to the Chrome browser in ~3 seconds; users can switch to Windows later as desired.

An anonymous reader writes "The FreeBSD Release Engineering Team is pleased to announce the availability of FreeBSD 8 stable release. Some of the highlights: Xen DomU support, network stack virtualization, stack-smashing protection, TTY layer rewrite, much improved ZFS v13, a new USB stack, multicast updates including IGMPv3, vimage — a new virtualization container, Fedora 10 Linux binary compatibility to run Linux software such as Flash 10 and others, trusted BSD MAC (Mandatory Access Control), and rewritten NFS client/server introducing NFSv4. Inclusion of improved device mmap() extensions will allow the technical implementation of a 64-bit Nvidia display driver for the x86-64 platform. The GNOME desktop environment has been upgraded to 2.26.3, KDE to 4.3.1, and Firefox to 3.5.5. There is also an in-depth look at the new features and major architectural changes in FreeBSD 8.0, including a screenshot tour, upgrade instructions are posted here. You can grab the latest version from FreeBSD from the mirrors (main ftp server) or via BitTorrent.

An anonymous reader writes "I was put in charge of an aging IT infrastructure that needs a serious overhaul. Current services include the usual suspects, i.e. www, ftp, email, dns, firewall, DHCP — and some more. In most cases, each service runs on its own hardware, some of them for the last seven years straight. The machines still can (mostly) handle the load that ~150 people in multiple offices put on them, but there's hardly any fallback if any of the services die or an office is disconnected. Now, as the hardware must be replaced, I'd like to buff things up a bit: distributed instances of services (at least one instance per office) and a fallback/load-balancing scheme (either to an instance in another office or a duplicated one within the same). Services running on virtualized servers hosted by a single reasonably-sized machine per office (plus one for testing and a spare) seem to recommend themselves. What's you experience with virtualization of services and implementing fallback/load-balancing schemes? What's Best Practice for an update like this? I'm interested in your success stories and anecdotes, but also pointers and (book) references. Thanks!"

snydeq writes "InfoWorld's Dan Tynan surveys six 'transformational' tech-panacea sales pitches that have left egg on at least some IT department faces. Billed with legendary promises, each of the six technologies — five old, one new — has earned the dubious distinction of being the hype king of its respective era, falling far short of legendary promises. Consultant greed, analyst oversight, dirty vendor tricks — 'the one thing you can count on in the land of IT is a slick vendor presentation and a whole lot of hype. Eras shift, technologies change, but the sales pitch always sounds eerily familiar. In virtually every decade there's at least one transformational technology that promises to revolutionize the enterprise, slash operational costs, reduce capital expenditures, align your IT initiatives with your core business practices, boost employee productivity, and leave your breath clean and minty fresh.' Today, cloud computing, virtualization, and tablet PCs are vying for the hype crown." What other horrible hype stories do some of our seasoned vets have?

AdamWill writes "The Fedora project has announced the release of Fedora 12 Beta, which is available here. This will be the final pre-release before the final release in November.

dan_johns writes "Only one month after Microsoft released Linux code to improve the performance of Linux guests on Windows, Red Hat has done the reverse. Red Hat has quietly released a set of drivers to improve the performance of Windows guests hosted on Linux's Kernel-based Virtual Machine (KVM) hypervisor. The netkvm driver is a network driver and viostor is a Storport driver to improve the performance of high-end storage. This release includes paravirtual block drivers for Windows. Linux and Windows — virtually coming together at last."

Voyager529 writes "While virtually every Core 2 Duo processor supports the hardware virtualization technology that powers the Windows 7 XP Mode, The Register UK reports that the Core 2 Duo processors in the Sony Vaio Z series laptops had the virtualization features intentionally crippled in the BIOS. Senior manager for product marketing Xavier Lauwaert stated that the QA engineers did this to make the systems more resilient against malicious code. He also stated that while they are considering enabling VT in some laptop models due to the backlash, the Z series are not among those being retrofitted."
