MsManhattan writes "VMWare Inc. today is slated to introduce a new version of its workstation virtualization software that supports Windows Vista. The upgrade, VMWare Workstation 6, enables users to run Vista as a host or a guest operating system. Additionally, it allows users to store a virtual machine setup on a portable device — like as a USB drive — and transfer the set-up to another computer. Virtualization, an old concept that has gained new momentum, can help organizations optimize their infrastructures but it can also create expensive management headaches. Just the same, the analyst group Gartner predicts that three million virtual machines will be in use by 2009, up from today's 500,000."

_Sharp'r_ asks: "I'm trying to design the least expensive way to make OpenOffice, email, and a web browser available to students in a new charter elementary school. In my past experience working with charitable computer donations, I can usually get three to four working computers out of five donated 'broken' computer systems, usually with plenty of monitors, keyboards and mice left over. I'd like to use one computer for multiple students by attaching multiple monitors, USB keyboards and mice. What drivers/OS versions support multiple local input devices and monitors that can be attached to a specific login session? Will this require virtualization? Is there a config I haven't found that you can use to assign these devices to specific ttys? Have you done this before?"

diegocgteleline.es writes "Linus Torvalds has released Linux 2.6.21 after months of development. This release improves the virtualization with VMI, a paravirtualization interface that will be used by Vmware. KVM does get initial paravirtualization support along with live migration and host suspend/resume support. 2.6.21 also gets a tickless idle loop mechanism called 'Dynticks', built in top of 'clockevents', another feature that unifies the timer handling and brings true high-resolution timers. Other features are: bigger kernel parameter-line, support for the PA SEMI PWRficient CPU and for the Cell-based 'celleb' Toshiba architecture, NFS IPv6 support, IPv4 IPv6 IPSEC tunneling, UFS2 write, kprobes for PPC32, kexec and oprofile for ARM, public key encryption for ecryptfs, Fcrypt and Camilla cipher algorithms, NAT port randomization, audit lockdown mode, some new drivers and many other small improvements."

An anonymous reader writes "Microsoft says there are over 1,000 applications you can run on Windows Vista with few, if any, issues. However, Windows apps number in the tens of thousands. Add to that the facts that x64 Vista versions don't support legacy 16-bit code, and that the Windows Resource Protection in Vista breaks some apps, and you've got a big issue. InformationWeek lists a host of workarounds in How To Manage Windows Vista Application Compatibility. Among the tips discussed are Vista's compatibility mode, its Program Compatibility Assistant wizard, and a little-known form of file and registry virtualization that's built into the OS. What problems have you encountered with incompatible apps, and are any issues you've encountered deal-breakers that could further roil the already muddied adoption picture for Vista?"

ktwdallas writes "Mathew Ingram from Canada's Globe and Mail writes that Microsoft will require at least the $299 Business version of Vista or higher if installing on a Mac with virtualization. Running the cheaper Basic or Premium versions would be a violation of their user agreement. According to the article, Microsoft's reasoning is 'because of security issues with virtualization technology'. Sounds suspiciously like a 'Mac penalty' cost that Microsoft is trying to justify."

jonesy16 writes "Only a few weeks behind the release of Red Hat Enterprise 5, CentOS announced today the immediate release of version 5 of the free derivative of RHEL 5. Torrents are available for both i386 and x86_64. New features include compiz and AIGLX support as well as better virtualization and thin-client support. Package updates include Apache-2.2, kernel-2.6.18, Gnome-2.16, and KDE-3.5."

czei writes "This just-released research report, Load Testing a Virtual Web Application, looks at the effects of virtualization on a typical ASP Web application, using VMWare on Linux to host a Windows OS and IIS web server. While virtualizing the server made it easier to manage, the number of users the virtualized Web app could handle dropped by 43%. The article also shows interesting graphs of how hyper-threading affected the performance of IIS." The report urges readers to take this research as a data point. No optimization was done on host or guest OS parameters.

An anonymous reader writes "To debug the FreeBSD kernel core dump efficiently, it is best to set up a remote debugging session between a development machine and the target machine, and remotely debug the kernel using serial communication. This article shows you how you can debug as many kernel images as you want; it becomes transparent to users once debugging starts, and your system's performance is not affected at all."

An anonymous reader writes "Vendors and magazines are all over virtualization like a rash, like it is the Saviour for IT-kind. Not always, writes analyst Andi Mann in Computerworld." I've found that when it works, it's really cool, but it does add a layer of complexity that wasn't there before. Then again, having a disk image be a 'machine' is amazingly useful sometimes.

coondoggie sends us a NetworkWorld story on the prospects for Apple gaining market share in the corporation. A number of factors are helping to catch the eye of those responsible for upgrading desktops and servers, the article claims: "Apple's shift to the Intel architecture; the inclusion of infrastructure and interoperability hooks, such as directory services, in the Mac OS X Server; dual-boot capabilities; clustering and storage technology; third-party virtualization software; and comparison shopping, which is being fostered by migration costs and hardware overhauls associated with Microsoft's Vista." On this last point, one network admin is quoted: "The changes in Vista are significant enough that we think we can absorb the change going to Macs just as easily as going to Vista."

An anonymous reader writes "VMWare released a white paper detailing its concerns with license changes on Microsoft software that may limit the ability to move virtual-machine software around data centers to automate the management of computing work. Two choice quotes: '"Microsoft is looking for any way it can to gain the upper hand," said Diane Greene, the president of VMware.' And, '"This seems to be a far more subtle, informed and polished form of competitive aggression than we've seen from Microsoft in the past," said Andrew I. Gavil, a law professor at Howard University. "And Microsoft has no obligation to facilitate a competitor."'"

Rob writes in with an article from CBROnline based on an interview with Microsoft's UK server director. He says the timing of the release of the next version of Microsoft's server OS, dubbed Longhorn, depends on the company getting virtualization ready to go. Microsoft has apparently decided to embed its hypervisor technology into Windows, an OS-centric approach to virtualization shared by XenSource Inc., its open-source rival and partner. This contrasts with the model of virtualizing the hardware layer being pursued by VMWare. The Microsoft spokesman is coy about a release date for Longhorn, saying it could be earlier or it could be later (but it should be in 2007).

Watt's up writes "A new study shows an alarming increase in server power consumption over the past five years. In the US, servers (including cooling equipment) consumes 1.2% of all the electricity in 2005, up from 0.6% in 2000. The trend is similar worldwide. 'If current trends continue, server electricity usage will jump 40 percent by 2010, driven in part by the rise of cheap blade servers, which increase overall power use faster than larger ones. Virtualization and consolidation of servers will work against this trend, though, and it's difficult to predict what will happen as data centers increasingly standardize on power-efficient chips." We also had a recent discussion of power consumption in consumer PCs that you might find interesting.

seriouslywtf writes in with a look at the current state of the question: will people eventually be able to run Mac OS X in a virtual machine, either on the Mac or under Windows? Ars Technica has articles outlining the positions of two VM vendors, Parallels and VMWare. Both have told Ars unequivocally that they won't enable users to virtualize OS X until Apple explicitly gives them the thumbs up. First, Parallels: "'We won't enable this kind of functionality until Apple gives their blessing for a few reasons,' Rudolph told Ars. 'First, we're concerned about our users — we are never going to encourage illegal activity that could open our users up to compromised machines or any sort of legal action. This is the same reason why we always insist on using a fully-licensed, genuine copy of Windows in a virtual machine — it's safer, more stable, fully supported, and completely legal.'" And from VMWare: "'We're very interested in running Mac OS X in a virtual machine because it opens up a ton of interesting use cases, but until Apple changes its licensing policy, we prefer to not speculate about running Mac OS X in a virtualized environment,' Krishnamurti added."

Gr8Apes writes "AMD has showcased their new 65nm Barcelona quad-core CPU. It is labeled a quad-core Opteron, but according to Infoworld's Tom Yeager, is really a redefinition of x86. Each core has a new vector math processing unit (SSE128), separate integer and floating point schedulers, and new nested paging tables (to vastly improve hardware virtualization). According to AMD, the new vector math units alone should improve floating point operation by 80%. Some analysts are skeptical, waiting for benchmarks. Will AMD dethrone Intel again? Only time will tell."

An anonymous reader writes "Mac users wanting to run Vista on their Macintosh, alongside Mac OS X programs, will have to buy an expensive version of Vista if they want to legally install it on their systems. The end-user license agreement for the cheaper versions of Vista (Home Basic and Home Premium) explicitly forbids the use of those versions on virtual machines (i.e., Macs pretending to be PCs)." Update: 02/08 17:50 GMT by KD : A number of readers have pointed out that the Vista EULA does not forbid installing it via Apple's Bootcamp; that is, the "tax" only applies to running Vista under virtualization.

diegocgteleline.es writes "After two months of development, Linux 2.6.20 has been released. This release includes two different virtualization implementations: KVM: full-virtualization capabilities using Intel/AMD virtualization extensions and a paravirtualization implementation usable by different hypervisors. Additionally, 2.6.20 includes PS3 support, a fault injection debugging feature, UDP-lite support, better per-process IO accounting, relative atime, relocatable x86 kernel, some x86 microoptimizations, lockless radix-tree readside, shared pagetables for hugetbl, and many other things. Read the list of changes for more details."

snoukka writes "I just bought a new HP nx9420 laptop in order to use it with Linux, XEN, and windows on XEN. I was very disappointed when I noticed that the processor had this feature but VT is disabled in BIOS by HP and cannot be enabled! Disabled!? It's like buying a car with turbo and finding out after buying it that this turbo 'feature' was disabled." The forum thread goes back to last August and is still live. The latest post from an HP rep indicates that new firmware for the nx9420 should be available later this week in which the ability to switch on VT is enabled. It's not clear whether other HP products, in which VT was also disabled, will also get new firmware.
