VMware Workstation vs. VirtualBox vs. Parallels 289

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.'"

The Book of Xen 88

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.

Red Hat Open Sources SPICE Desktop Virtualization 79

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."

IBM's Newest Mainframe Is All Linux 251

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."

VMware's Dual OS Smartphone Virtualization Plan Firms Up 179

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.

Chrome OS, Present and Future 132

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.

Best Practices For Infrastructure Upgrade? 264

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!"

IT Snake Oil — Six Tech Cure-Alls That Went Bunk 483

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?

Red Hat Releases Windows Virtualization Code 183

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."

No Windows 7 XP Mode For Sony Vaio Z Owners 198

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."

AMD's OpenCL Allows GPU Code To Run On X86 CPUs 176

eldavojohn writes "Two blog posts from AMD are causing a stir in the GPU community. AMD has created and released the industry's first OpenCL which allows developers to code against AMD's graphics API (normally only used for their GPUs) and run it on any x86 CPU. Now, as a developer, you can divide the workload between the two as you see fit instead of having to commit to either GPU or CPU. Ars has more details."

Windows Drains MacBook's Battery; Who's To Blame? 396

ericatcw writes "Users hoping that Windows 7's arrival will mean less power drain on their MacBook laptops may be disappointed, writes Computerworld's Eric Lai. Running Windows 7 in Boot Camp caused one CNET reviewer's battery life to fall by more than two-thirds. But virtualization software such as VMware Fusion suffer from the same complaints. Some blame Apple's Boot Camp drivers (the last ones were released in April 2008); others lay the blame at Windows' bloated codebase. With Apple and Microsoft both trying to avoid responsibility for improving the experience, Windows 7's reported improvements in power management will be moot for MacBook users for a while."

Entropy Problems For Linux In the Cloud 179

CalTrumpet writes "Our research group recently spoke at Black Hat USA on the topic of cloud computing security. One of the interesting outcomes of our research was the discovery that the combination of virtualization technologies and public system images results in a problem for random number generation on guest operating systems. This is especially true for Linux, since its PRNG uses only a small set of entropy-gathering events, and virtual Linux images often generate SSH host keys within seconds of their initial boot. The slides are available; the PRNG vulnerability material begins at slide 63."

Cloud-Sourcing's Long-Term Impact On IT Careers 157

snydeq writes "InfoWorld provides a reality check on the impact cloud computing will have on IT jobs, the overall effects of which will likely resemble those of outsourcing, automation, and utility computing — in other words, a movement away from the nuts and bolts of technology toward the business end of the organization. This shift from 'blue-collar IT to white-collar IT' will be accompanied by greater demand for IT pros experienced with virtualization and Web scale-out deployments, even among midlevel organizations, and greater emphasis on SaaS integration among in-house development teams, analysts say. And though the large-scale impact of 'cloud-sourcing' is likely a decade away, those not versed in vendor contract management, cloud integration, analytics, and RIA and mobile development may find themselves pushed toward the less technical jobs to come, those that will require days full of conference calls and putting out fires caused by doing business in the cloud."
