Microsoft whitepaper: Using Domain Controller Virtual Machines
: "Running domain controllers in virtual machines is best suited for test and pre-production piloting environments. With strict adherence to the requirements described in this document, domain controllers running in virtual machines can also be used in a production environment." 10:53:48 PM

VMWare Book Preview Chapter Available
: "VMWare ESX Server: Advanced Technical Design Guide will be a real-world architectural field guide that shows you how to design VMWare ESX environments. .. The book will be available in April 2005. A preview chapter
is now available for download. .. This huge chapter goes into all the details you need to understand to design a guest environment, including master installation, ISO management, virtual machine networking, controlling resource usage, managing DSK files, and virtual machine deployment. We'll bring more chapters online over the next several months. " 9:00:07 AM

Microsoft ponders licensing for app virtualization
: "Noting two evolving areas of software licensing, Microsoft is pondering how to license when multiple instances of an application are run on a single computer, but is not eyeing a plan for utility-based computing, in which charges are based on individual usage. .. Right now, Microsoft charges based on hardware capabilities irrespective of software partitioning or virtualization. A user site might have 1,000 virtual machines running 1,000 instances of the same application, deployed on a four-processor computer, he said. Under current policy, the user would be charged for four processors, not for running the application 1,000 times. " MS also announced it would charge single-processor prices for multi-core processors. 9:06:12 AM

CherryOS turns your PC into a Mac:
"Hawaii-based MXS has released a piece of software that turns a Windows computer into a Mac. CherryOS turns a PC into a Macintosh clone, allowing you to run MacOS and Macintosh applications directly on your PC. The software works by running the Mac OS as a virtual machine on your Windows PC. The virtual machine has full network capabilities, according to the company, including the ability to share folders, access the Internet, and create multiple profiles. It purportedly runs at about 80 per cent of the performance of the host CPU, according to the developer. Note that a Mac operating system and application software is not included.

VMware ACE Takes Virtual Machines Mobile
: "VMware ACE (assured computing environment) administrators can put everything from operating systems, applications and data onto a DVD, which can then be loaded onto a worker's PC, said Michael Mullany, vice president of marketing at VMware.
They also can set policies, via Virtual Rights Management technology, that range from how long the environment will be in effect to who can access what information in the network, Mullany said. In addition, the hardware-agnostic software offers copy-protection controls and automatic encryption, protecting against unauthorized copying of network information.
ACE's isolated computing environments will enable enterprises to give telecommuters and contract workers a way to securely get onto the network without the company having to give them a company computer while at the same time protecting the network from various viruses. Businesses also don't need to build specific hardware images for the computers. Instead, for example, if contractors are hired for 60 days, ACE is loaded onto their computer and administrators can set it to expire after those 60 days. " 10:08:27 PM

Open source startup interruptus? A skeptical opinion of startups SourceLabs and SpikeSource, aimed at supporting enterprise open source applications: "I find it hard to see how either company will be anything more than minimally succesful against the likes of Red Hat, IBM or HP. The semi-logical conclusion is that both companies were started with exit strategies already in place. Some free advice to the founders: Sell your companies. Sell them quickly. Take the first offer that comes in. "
A member of SourceLabs replies in a comment, "The goal is not to sell a certified stack, it is to sell support for a certified stack. We will give away the certified stack. You will only have to pay if you want support for it. Certification carries two purposes: the first is to make customers feel comfortable enough to run the stack, and the second is for us to make sure that it is stable enough to provide support for it." 10:39:14 PM
RAID 1 on Linux:
Some of the fine points of configuring disks on Linux. 8:55:40 AM
Polese steps into open-source fray: Kim Polese, a former Sun Microsystems executive who was the original product manager for Java, is now at the helm of SpikeSource, an open-source software services company that launched on Thursday .. Services will include support and product certification as well as consulting for corporate IT staff during the application development and installation process, according to the company. .. By the end of the year, the company intends to launch a beta test of its services for the LAMP and LAMPJ "stacks" of open-source infrastructure software, according to the company's Web site. ..
SpikeSource appears to already have a competitor. Another group of industry veterans, including former Microsoft executives Brad Silverberg and Adam Bosworth, is backing SourceLab, which launched last week. The company intends to offer similar support and installation services around bundled open source components on a subscription basis" 12:19:08 AM
IBM Virtualization Capabilities with Linux and POWER5
: Info on machine architecture and issues from their point of view. " Itís now putting the number of services per administrator as the metric to measure your IT infrastructure, as opposed to the number of servers per administrator. Thatís revolutionary, because originally we would measure an IT administratorís relative skill set based on the number of physical boxes he or she could maintain.
And those administrators with different platform expertise had different expected numbers. A Sun admin may be able to do 30 or 40, where a Microsoft admin would be expected to do 10 to 20. Thatís based on the number of problems, support required, updates, packages, problems of that nature. Essentially now weíre taking those physical boxes out of the equation. " 12:02:21 AM

Red Hat builds on Netscape security acquisition, virtualization plan
: "The company is also planning to add server virtualization functionality to the Open Source Architecture with Red Hat Enterprise Linux 5. "Virtualization right now with regard to Linux is the next big thing, it's the next evolution of the operating system opening up many more possibilities," said Cormier.
Red Hat currently partners with VMware Inc for its virtualization technology, but the indications are that the company will turn to open source virtualization projects that will be tightly integrated into the Open Source Architecture. .. "What happens more often now with our customers is they say: 'I'm watching the development going on with Xen or UML [User-Mode Linux] in the virtualizations space, do what you did in the operating system for that, commercialize that'." Xen is an open source virtual machine monitor project for x86 systems from the University of Cambridge, UK's Computer Laboratory, while User-mode Linux is a patch for the Linux kernel that enables virtual machines." The article implies that Enterprise Linux 5 will come in the second half of 2005. 12:00:40 AM
