It looks like the newest version of the Linux kernel (2.6.20) will include KVM, the relatively new virtualization environment. From the article: "Thanks to its approach KVM already runs in the current kernel, without any extensive bouts of patching and compiling being required, after the fairly simple compilation of a module. Virtual machines that run unmodified operating systems are meant to appear in the host as a simple process and work independently of the host kernel. In a fashion comparable to that of Xen a modified QEMU is used for the supportive emulation of typical PC components of the virtual machines."

Verunks writes "Parallels has released a new beta of its virtualization product for Mac OS X. This new release includes one major new feature, something Parallels calls Coherency: "Shows Windows applications as if they were Mac ones. Try it and enjoy best of both worlds truly at the same time. No more switching between Windows to Mac OS." Check out this Screenshot" More interesting to me is the Boot Camp support so you can have a single partition to run IE7 in Parallels to test compatibility of a website but reboot to play video games that need a little more juice.

davidmcg writes "Finally, Microsoft has made steps to make testing IE6 and IE7 easier for Windows users. Previously, you had to pay for an additional Windows license to legally run both versions of IE for testing purposes. Now Microsoft is making available free Windows XP/IE6 images available for VirtualPC (also free as MS is competing with VMWare). This means that you can run IE6 in a virtual machine while running IE7 on your host machine. The drawback is that the download is set to expire April 2007 ... although we are promised new versions will be released. What Microsoft doesn't mention is that Virtual PC also runs on Windows 2000 (and IE7 doesn't). Therefore it's possible to install this Windows XP VPC image on your Win2k machine. You can then update IE6 on the XP image to IE7, testing IE7 without upgrading from Win2k. This is all-around excellent news for web developers."

raffe writes "Here is a Q&A with Ron Hovsepian CEO of Novell. He describes 'a love-hate thing' between the two companies." From the article: "This past May, I picked up the phone and called Kevin Turner, the COO at Microsoft. I knew Kevin when he was the CIO at Wal-Mart. I said, "Kevin, I'd like to have a conversation about what the customer needs. If you could put back on your old hat as a customer, if I came in and started talking to you about virtualization on Linux, and this Microsoft guy showed up and started talking to you about virtualization on Windows, what would you say to us?""

Maxx writes to mention a ZDNet article about Microsoft's dictum on Vista as a virtual machine. The software giant has declared that home versions of their upcoming OS may not be run virtually, because 'virtualization is not mature enough for broad adoption.' From the article: "'Microsoft says that consumers don't understand the risks of running virtual machines, and they only want enterprises that understand the risks to run Vista on a VM. So, Microsoft removes user choice in the name of security,' says Gartner analyst Michael Silver. 'The other option is to pay Microsoft US$300 for Windows Vista Business or US$399 for Windows Ultimate, instead of US$200 for Home Basic or US$239 for Home Premium,' Silver suggested."

Nirav Mehta writes to mention a Techworld article about this past week's virtualization announcements at VMWorld 2006. VMWare had several new offerings in the event's third year. From the article: "VMware has released details of ACE 2.0, which is due for release towards the middle of 2007. The product, which was demonstrated in alpha at VMworld this week, allows administrators to distribute pre-packaged virtual machines to users in a secure manner. This means, for instance, that contractors can be allowed to attach to the enterprise network using their own laptops but only via the ACE VM. The new version was created, according to VMware, because users asked for greater control over the VMs, especially when, for instance, large numbers of remote users need to attach to the enterprise network. Other areas due for improvement include security and integration with enterprise management tools. "

Unwanted Software writes "There's an interesting interview on eWeek with Joanna Rutkowska, the stealth malware researcher who created 'Blue Pill' VM rootkit and planted an unsigned driver on Windows Vista, bypassing the new device driver signing policy. She roundly dismisses the quality of existing anti-virus/anti-rootkit products and makes the argument that the world is not ready for VM technology. From the article: 'Hardware virtualization, as recently introduced by Intel and AMD, is very powerful technology. It's my personal opinion that this technology has been introduced a little bit too early, before the major operating system vendors were able to redesign their systems so that they could make a conscious use of this technology, hopefully preventing its abuse.'"

Dell has two new servers - the PowerEdge 6950, designed for database applications, server consolidation, and virtualization; and the PowerEdge SC1435 designed for high-performance compute clusters. Both servers are based on AMD's Opteron processor. This is the result of the AMD/Dell effort to match customer needs with AMD and Dell technology.

Sun is continuing to tweak its "Galaxy" line of Sun Fire Opteron-based servers to they can support the new "Santa Rosa" Rev F Opteron processors from AMD . "The initial Galaxy boxes from fall 2005 were based on the Rev E iteration of the Opteron chips, which come in a 940-pin package. The Rev Es have an integrated DDR1 main memory controller on the chip. The Rev F chips come in a 1207-pin package that has a completely different processor socket and, because they also support DDR2 main memory, they also have a different main memory controller on the chip. What this means is that even though the cores in the Rev E and Rev F processors are essentially the same--the other big change is that the Rev F chips support the hardware-assisted virtualization feature code-named "Pacifica" and now known as AMD-V--the server boards that Sun created for the Galaxy line have to be changed to make use of the new Rev F processors. AMD has also created a modified 940-pin variant of the Rev F Opteron chips called the AM2 socket for entry servers and workstations."

Emulex's LightPulse family of 4 Gb/s HBAs is showing great results with AMD Opteron processor-based systems. "Emulex 4 Gb/s HBAs running in conjunction with AMD Opteron processors provide as much as a 78 percent performance advantage across a range of I/O workload requests when compared with competitive offerings." Emulex and AMD have worked closely together to promote interoperability, and to ensure customer have access to performance-driven solutions. "In addition, Emulex is working with AMD to develop solutions around next-generation products, such as those optimized for server virtualization environments." "The high-performance combination of Emulex's flexible and reliable 4 Gb/s HBAs with the AMD Opteron processor delivers unique and compelling benefits to our customers who require high levels of performance," said Mike Smith, executive vice president of worldwide marketing, Emulex. "Working with AMD to deliver industry-leading, high-performance solutions also ensures support for next-generation technology innovation, such as server virtualization."

An anonymous reader writes "When AM2 was first announced it seemed like it was going to be a guaranteed hit. After all, this platform would be moving the tremendously successful socket 939 into the future with its use of DDR2 memory, a greatly increased memory bandwidth, hardware virtualization, and a number of exciting new CPUs. Despite everything AM2 had going for it, this includes a dedicated enthusiast base and a tremendous amount of pro-AMD spirit at the time, the new platform has largely been dismissed by consumers. The question now is, what happened? How did AMD go from record growth and being the darling of enthusiasts to having a new platform which failed to impress?"

sunshineluv7 writes, "IT managers gathered in New York City earlier this week to get advice from experts on when, why, and how to virtualize their server environments. The takeaway from the conference: if you want to run an enterprise-class virtualization platform in production today, stick with VMware." Other wise words from this conference: "Virtualization is a journey, not a project."

nezmar writes, "MacGeekery has a short but insightful piece with examples on how to use a malformed Installer package (.pkg) on Mac OS X to 'insert user accounts with administrator rights and change root-owned system configuration or binary files without prompting the vast majority of Mac OS X users for a password of any kind.'" The article notes that this issue was brought up on the Apple Discussion Boards 6 weeks back and that it was noted there as a duplicate / known issue. It also gives as an example the installation of Parallels, the popular virtualization software, which uses the described technique, but not for nefarious purposes.

The lineup will feature Jeff Waugh of Ubuntu and GNOME, Linux International's Jon 'maddog' Hall, Jorge Castro, MySQL's Jay Pipes, Michael Johnson, a panel on virtualization, and many more excellent speakers. The OhioLinuxFest will take place on Saturday, September 30 at the Greater Columbus Convention Center in Columbus, Ohio. Registration is free."

An anonymous reader wrote to mention a TechWorld story about Windows Vista. According to the Gartner Group, Windows Vista is likely to be the last of its kind. "The problem is that the operating system's increasing complexity is making it ever more difficult for enterprises to implement migrations, and impossible for Microsoft to release regular updates. This, in turn, stands in the way of Microsoft's efforts to push companies to subscription licensing. The answer, according to Gartner, is virtualization, which is built into newer chips from Intel and AMD, and has become mainstream for x86 servers through the efforts of VMware." Speaking of Vista, C|Net reports that a new release candidate is on the way. The average tester should expect it by the end of September.

Jim Buzbee writes "Those you keeping up with the latest virtualization techniques being offered by both Intel and AMD will be interested in a new white paper by VMWare that comes to the surprising conclusion that hardware-assisted x86 virtualization oftentimes fails to outperform software-assisted virtualization. My reading of the paper says that this counterintuitive result is often due to the fact that hardware-assisted virtualization relies on expensive traps to catch privileged instructions while software-assisted virtualization uses inexpensive software substitutions. One example given is compilation of a Linux kernel under a virtualized Linux OS. Native wall-clock time: 265 seconds. Software-assisted virtualization: 393 seconds. Hardware-assisted virtualization: 484 seconds. Ouch. It sounds to me like a hybrid approach may be the best answer to the virtualization problem. "

porjo writes "Peace has been established on at least one front: XenSource and VMware are working together to improve virtualization in the Linux kernel. Their original disagreement has been displaced by a commitment to work on a solution together, says Simon Crosby, CTO of XenSource, the company that builds products around Xen virtualization software. The two are trying to come up with a common approach to virtualization support in the Linux kernel. [snip] The work now under way would let hypervisors from Microsoft, VMware, and Xen work together in the same data center. Under such a scenario, it would be possible for a Xen virtual machine, trapped on a piece of failing hardware, to be automatically moved over to a VMware hypervisor on another piece of hardware."

njyoder writes "As previously posted about, Joanna Rutkowska claimed to have discovered an allegedly undetectable vulnerability in Vista that takes advantage of AMD cpu's virtualization capabilities. a virtualization professional (Anthony Liguori of the Xen project) has now voiced his opinion to state this is bunkum. There are two parts two this — the ability to take over the machine and seamlessly drop the OS into a VM (which is very difficult, but possible) and the ability to have windows run in the VM undetectably (which is impossible). In fact, Rutkowska's prototype is VERY detectable. This is unfortunate mistake that people make when they jump to conclusions based on what is unfounded speculation and that includes the assumption that this would somehow be Vista specific, if it worked (noting that Vista doesn't run with administrator privileges by default)."

daria42 writes "Novell has fired back at Red Hat's claims that the open source Xen virtualization software is not yet ready for enterprise use. 'We had all the major hardware partners that had virtualization hardware like IBM, Intel and AMD. They all stood up and said "Yes, this technology's ready, and we fully support deployments based on Xen and in combination with SUSE Linux Enterprise 10."', Novell's chief technology officer said today. 'So I guess the other vendors would not do that if it weren't ready.'"

sunshineluv7 writes to tell us TechTarget is running a good overview of 'why, when, and how to use virtualization technologies to consolidate server workloads.' The summary provides links to several podcasts and other articles relating real world experience with how to utilize virtualization to best meet your needs. From the summary: "Advances in 64-bit computing are just one reason that IT managers are taking a hard look at virtualization technologies outside the confines of the traditional data center, says Jan Stafford, senior editor of SearchServerVirtualization.com."
