Triple Booting an Intel Mac the Right Way 101

Miah Clayton writes "In the past, installing Mac OS X, Linux, and Windows on an Intel mac meant that you were forced into only having 3 usable partition slots due to the MBR/GPT hybrid limitations. Steven Noonan figured out a way to avoid dealing with the MBR partition limit and have a Linux install that isn't performance-crippled by having a swap file instead of a swap partition."

When Does Powering Down Servers Make Sense? 301

snydeq writes "Powering down servers to conserve energy is a controversial practice that, if undertaken wisely, could greatly benefit IT in its quest to rein in energy costs in the datacenter. Though power cycling's long-term effects on server hardware may be mythical, its effects on IT and business operations are certainly real and often detrimental. Yet, development, staging, batch processing, failover — several server environments seem like prime candidates for routine power cycling to reduce datacenter energy consumption. Under what conditions and in what environments does powering down servers seem to make the most economic and operational sense, and what tips do folks have to offer to those considering making use of the practice?"

Credit Card Security Standard Issued 98

alphadogg writes "The Payment Card Industry Security Standards Council, the organization that sets technical requirements for processing credit- and debit-cards, Wednesday issued revised security rules, while also indicating next year it will focus on new guidelines for end-to-end encryption, payment machines and virtualization. PCI adherence has been pushed big time in the industry to help avoid more big breaches such as the one involving TJX. Those familiar with the standard say it could be expensive to implement and that there are some things those using wireless LANs will need to pay especially close attention to."

Inside VMware's 'Virtual Datacenter OS' 121

snydeq writes "Neil McAllister cuts through VMware's marketing hype to examine the potential impact of VMware's newly pronounced 'virtual datacenter OS' — which the company has touted as the death knell for the traditional OS. Literally an operating system for the virtual datacenter, VDC OS is an umbrella concept to build services and APIs that make it easier to provision and allocate resources for apps in an abstract way. Under the system, McAllister writes, apps are reduced to 'application workloads' tailored through vApp, a tool that will allow developers to 'encapsulate the entire app infrastructure in a single bundle — servers and all.' The concept could help solve the current bugbear of programming, parallel processing, McAllister concludes, assuming VMware succeeds."

Sun Bare Metal Hypervisors Now GPLv3 154

ruphus13 writes with some more news for people foretelling the death of VMware. Sun has open sourced their xVM server, their bare-metal hypervisor virtualization solution. What used to once be the cash cow for VMware is now coming under increased threat, and Sun is once again turning to the Open Source community as a weapon. "Sun xVM Server is an outgrowth of the Xen project — which raises the question of why a company would go with Sun's version rather than the Xen one. Apart from its support for SPARC and Solaris (as well as other chips and operating systems), Sun is also building a services and sales organization around a commercial version of xVM server... If you want to kick the tires or cut your costs, you can hop over to xVMServer.org, download the source (GPL 3) and join the community. But Sun is betting that, as deployments move from an initial testing phase to active usage, large organizations will be willing to pay for guaranteed support (starting at $500 per year per physical server)."

Microsoft Working On "Post-Windows" Cloud Computing OS 208

Barence writes "Microsoft is working on a web-based operating system called Midori, as it looks to life beyond Windows. Midori is expected to be a cloud-computing service, and so not as dependent on hardware as current generations of Windows. It's also expected to run with a virtualization layer between the hardware and the OS, and is expected to be a commercial offshoot of the Singularity research project which Microsoft has been working on since 2003." If this story sounds familiar to you, it probably is.

Review of Sun's Free Open Source Virtual Machine 354

goombah99 writes "After snapping up virtualization company InnoTek at the beginning of the year, Sun has recently released VirtualBox as a fully functional and highly polished free GPL open source x86 Virtual Machine. It can host 32- or 64-bit Linux, Windows XP Vista and 98, OpenSolaris and DOS. It runs on Mac OS X, Windows, and Unix platforms. The download is just 27MB. A review of it on MacWorld, showing HD movies playing inside windows XP on a mac, demonstrates performance visually indistinguishable from VMware. Like its competition, it can run other OSes in rootless, rooted, or seamless modes display modes (where all the applications have their windows mixed at the same time). Each VM instance can only run single core (though I/O is multi-core), and it does not yet support advanced windows graphics libraries however, so some gamers may be disappointed. Slashdot discussed the InnoTek acquisition earlier.

Virtual Honeypots 50

rsiles writes "Honeynet solutions were seen just as a research technology a couple of years ago. It is not the case anymore. Due to the inherent constraints and limitations of the current and widely deployed intrusion detection solutions, like IDS/IPS and antivirus, it is time to extended our detection arsenal and capabilities with new tools: virtual honeypots. Do not get confused about the book title, specially about the "virtual" term. The main reason to mention virtual honeypots, although the book covers all kind of honeynet/honeypot technologies, is because during the last few years virtualization has been a key element in the deployment of honeynets. It has offered us a significant cost reduction, more flexibility, reusability and multiple benefits. The main drawback of this solution is the detection of virtual environments by some malware specimens." Read below for the rest of Raul's review.

VMware ESXi Available For Free Starting Today 241

Mierdaan writes "VMware's bare-metal hypervisor is available for free starting today. ESXi, which can either be installed or run from an embedded device available in certain servers, has a 32MB footprint and gives small businesses an easy way to get into the virtualization world, with easy upgrade paths to enterprise-level features such as (H)igh (A)vailability and (D)istributed (R)esource (S)cheduler. ESXi runs on most any hardware with a server-class disk controller, and previously retailed for $495. VMware is obviously shooting to prevent Microsoft's Hyper-V technology from gaining a foothold in the marketplace."

IT Jobs To Drop In 2009 393

ruphus13 writes "A new Goldman Sachs IT report recently released states that IT jobs will be dramatically reduced in 2009, starting with contract and offshore developers. From the article: 'Sharp reductions likely in contract staff, professional services and hardware, and almost no investment in cloud computing.' The article goes on to say 'The CIOs indicated that server virtualization and server consolidation are their No. 1 and No. 2 priorities. Following these two are cost-cutting, application integration, and data center consolidation. At the bottom of the list of IT priorities are grid computing, open-source software, content management and cloud computing (called on-demand/utility computing in the survey) — less than 2% of the respondents said cloud computing was a priority.' Postulating a 'pointy haired boss' problem, an analyst goes on to say, '[Grid computing, Open Source and Cloud computing] require a technical understanding to get to their importance. I don't think C-level executives and managers have that understanding.' But they do control the paychecks ..."

Building the Green Data Center 86

blackbearnh writes "O'Reilly News talked to Bill Coleman, former founder of BEA and current founder and CEO of Cassett Corporation, about the challenges involved in building more energy-efficient data centers. Coleman's company is trying to change the way resources in the data center are used, by more efficiently leveraging virtualization to utilize servers to a higher degree. In the interview, Coleman touches on this topic, but spends most of his time discussing how modern data centers grossly overcool and overdeploy hardware, leading to abysmal levels of efficiency."

Running Xen 98

David Martinjak writes "Running Xen: A Hands-On Guide to the Art of Virtualization was published by Prentice Hall, and authored by Jeanna N. Matthews, Eli M. Dow, Todd Deshane, Wenjin Hu, Jeremy Bongio, Patrick F. Wilbur, and Brendan Johnson. The book, which will be referred to as simply Running Xen, was a great resource on Xen and virtualization from the administration side. A wide range of topics was covered from installing Xen all the way up to managing virtual resources, including migrating guest environments. Overall, the explanations were concise and understandable; while the information was presented in a straightforward manner. Running Xen was definitely a useful resource for administering systems with Xen." Keep reading for the rest of David's review.

Gartner Reveals Top 10 Technologies For Next 4 Years 163

Dr. Jim writes "The good folks over at the Gartner Group have revealed the top 10 technologies that they believe will change the world over the next four years. The usual suspects including multi-core chips, virtualization, and cloud computing are on the list. Multicore servers and virtualization will mean that firms will need fewer boxes, and apps can be easily moved from box to box (and right out the door to an outsourced data center). Workplace social networks and cloud computing means that the need for a centralized IT department will go away. Firms will no longer need to own/maintain the boxes that they use to run their firm's apps. With no need to touch a box, there will be no need to have the IT staff co-located with the boxes."

IT Workers Are Getting Fatter 366

buzzardsbay writes "While technologies such as virtualization, multi-threading, and blade servers have made the data center leaner, those who work there are getting... well... not leaner. According to a new study by CareerBuilder.com, 34 percent of IT workers say they have gained more than ten pounds in their current jobs. And 16 percent say they've gained at least twice that. The culprits seem to be the stressful-yet-sedentary nature of tech work coupled with our famously poor eating habits. According to the survey, some 41 percent of IT workers eat out for lunch twice or more per week, making portion and calorie control difficult. Eleven percent buy their lunch out of a vending machine at least once a week."

Amazon EC2 Now More Ready for Application Hosting 149

For months now, I've been geeked about Amazon's EC2 as a web hosting service. But until today, in my opinion, it wasn't ready for prime time. Now it is, for two reasons. One, you can get static IPs, so if an outward-facing VM goes down you can quickly start another one and point your site's traffic to it without waiting for DNS propagation. And two, you can now separate your VMs into "physically distinct, independent infrastructure" zones, so you can plan to keep your site up if a tornado takes out one NOC. If I were developing a new website I'd host it there; buying or leasing real hardware for a startup seems silly. If you have questions, or especially if you know something about other companies' virtual hosting options, post comments -- let's compare notes.

Microsoft Hyper-V Leaves Linux Out In The Cold 212

whitehartstag writes to mention that Microsoft has announced their new Hyper-V as feature-complete. Unfortunately the list of supported systems is disappointingly short. "No offense to SUSE Enterprise Server crowd, but only providing SUSE support in Hyper-V is a huge mistake. By not supporting Red Hat, Fedora, CentOS, and BSD, Microsoft is telling us Hyper-V is a Microsoft only technology. More Mt. Redmond, Microsoft center of the universe thinking. That's disappointing. Sure, if you are a Microsoft only shop, Hyper-V will be an option for virtualization. But so will VMware and XenServer. But if you run a mixed shop, Hyper-V won't solve your problems alone — you'll have to also add VMware or Xen to your virtualized data center portfolio. Or just go with VMware and Xen and forego Hyper-V."
