The interview below is part of our Virtualization Video Series, a recurring theme we want to implement on Virtualization.com featuring interviews with key players from the industry, event reports, etc.

This interview was recorded at the Profoss 2008 event on Virtualisation and features Frank Kohler, Virtualization Project Manager at Suse (Novell) being interviewed by Toon Vanagt on what he saw his clients do with virtualization technology and how you can avoid making those mistakes. Shortly after the interview, Frank was hired by XenSource (Citrix).

VMWare’s Mike DiPetrillo Openly Critical About Citrix – Xensource

by 1 Comment

If you thought the leaked internal VMWare memo criticizing the partnership between Microsoft and Citrix was bad, get a load of this: Mike DiPetrillo, Specialist System Engineer of Industry Research and Competitive Analysis at VMWare (VMW) and one of VMWare’s bloggers, posted a rather critical blog post on his personal space yesterday attacking Citrix’ acquisition of Xensource.

Other than calling Xensource a ‘good little company’, DiPetrillo says he’s still trying to figure out why Citrix paid $ 500 million for it in the first place.

“In Q3 XenSource announced 1,000 customers. On the call they said they added another 400 customers. Good growth! That puts the total at 1,400 customers. Then came the partner count – 1,817 partners certified to sell XenSource. Hmmm. So now we have 1,817 partners trying to get business from the 1,400 customers that total $2 million in revenue (that’s $1,100 in revenue per partner). Good days to be a Citrix partner.”

He goes on to say:

“OK. So the strategy is go and spend $500 million on a company that’s losing money, switch all of your current successful products and branding over to the losing company, and then exit the market when your larger partner moves into the market. Is this the end of Citrix then? Terminal Services in Windows Server 2008 closes the gap pretty nicely. Virtual Desktops are also taking large chunks of market share. Time will tell where Citrix ends up.”

In the end, it’s fair critiscm and DiPetrillo does raise some good points, but coming from a VMWare employee (although published on his personal blog), the article is bound to make some people frown.

Virtualization start-ups hit reset button

by Leave a Comment

Two start-ups hoping to profit from virtualization are giving details of new strategies this week. It’s a sign that the technology, while a hot item, doesn’t mean easy profits.

Stephen Shankland wrote on news.com

Virtual Iron and XenSource both have altered course with their virtualization products, which is software that lets a single computer run multiple operating systems simultaneously. Virtual Iron has scrapped its own virtualization software in favor of the open-source Xen project. Meanwhile, the leader of that project, XenSource, is steering away from management tools and aiming squarely for virtualization leader VMware.

The two companies are describing their new strategies at the LinuxWorld Conference and Expo in Boston this week. And with more news in the area from VMware, Microsoft’s Virtual Server group and SWsoft, the show might well be called VirtualizationWorld.

If imitation is the sincerest form of flattery, VMware executives might blush at the strikingly similar rhetoric from Virtual Iron and XenSource.

“The market really wants a competitor to VMware,” said Simon Crosby, XenSource’s co-founder and chief technology officer.

“It’s time for a company to step up and be a viable commercial competitor to VMware,” said Virtual Iron Chief Executive John Thibault.

It’s no surprise why competitors are angling for advantage. A February Forrester survey of 1,221 customers with at least 1,000 employees found that 41 percent of North American customers are using virtualization already or are planning pilot tests. And 60 percent plan to spend more money on the technology in the next 12 months.

VMware leads the market, the study found, with 43 percent of customers considering it most often for x86 server virtualization, compared with 24 percent for Windows Virtual Server. Xen “is not yet on the radar for customers,” the report said.

Virtualization, in the form most widely discussed these days, lets a computer run many operating systems simultaneously and therefore lets administrators replace several largely idle servers with one efficiently used machine. The technology works by fooling programs into thinking that they’re running on real hardware, when they actually are running on a virtual layer called a hypervisor.

That sleight-of-hand means that operating systems can share the same hardware, or be moved while running from one computer to another to cope with hardware failure or new processing demands.

Virtualization is an established feature in higher-end servers. Now, since it’s arriving in mainstream models with x86 chips from Intel and Advanced Micro Devices, companies like Virtual Iron and XenSource are trying to commercialize it as a stand-alone technology.

A big change coming with virtualization support from AMD and Intel means that virtualization companies today can sidestep some of clever engineering techniques VMware employs. AMD Virtualization, set to debut in months, and Intel’s corresponding VT, which started arriving in 2005, permit Xen to run an unmodified operating system. In practice, that means Xen can run Microsoft Windows as well as Linux.

The side effect is that VMware will be getting more direct competition from XenSource and Virtual Iron. But that’s not all: Another start-up called Parallels also hopes to give VMware a run for its money.

Its $50 hypervisor-based Parallels Workstation 2.1 product runs on Windows and Linux desktop machines right now, and the company plans to launch a midrange server product in mid-2006 and a high-end server product in late 2006, Marketing Manager Benjamin Rudolph said.

Lining up at LinuxWorld
VMware is looking to sustain its leadership in part by opening up interfaces to control virtual machines and making its basic virtual machine software free. And Monday at LinuxWorld, it plans to announce a related move: The EMC subsidiary is offering its virtual machine disk format specification to all comers for royalty-free use. The format competes with Microsoft’s VHD specification and Xen’s XVM.

Several announcements on virtualization moves are expected at LinuxWorld, which has morphed substantially since it began in the 1990s, following the growing impact of open-source software. The conference’s annual East Coast edition runs Monday through Thursday in Boston.

In addition to exhibitors touting operating system-related technologies, representatives from open-source databases and middleware companies are also scheduled to attend. Sessions and keynotes will also cover the impact of open-source business models on the software industry overall, including one entitled “The Death of the Enterprise Software Business Model.”

At LinuxWorld, IBM plans to announce services to help customers design, install and configure virtual machines as a way to consolidate Linux servers. It’s a sign that Big Blue, a virtualization pioneer with its mainframe servers, is also trying to profit from the technology as it becomes mainstream.

Virtualizing at the operating system is one approach, but SWsoft is taking a higher-level approach that divides a single operating system into multiple virtual environments, each with its own independent applications. At the show, SWsoft plans to announce its Datacenter Automation Suite, a Web-based management tool for tasks such as launching new environments or filling them with software templates.

Xen is catching on in the Linux realm. Indeed, it’s being built into premium Linux products from Novell and Red Hat due by the end of the year, undermining the technology somewhat as a standalone product.

XenSource ‘parks’ XenOptimizer
That fact was part of why XenSource changed direction. “What we found out over last six months, talking to a lot with customers…is that the way they want to consume Xen is through Red Hat Enterprise Linux (or) Suse Linux,” Crosby said.

Those two Linux sellers now are XenSource business partners. That arrangement is one facet of XenSource’s business strategy, while selling a stand-alone product called XenEnterprise to compete with VMware is the other, Crosby said.

XenSource no longer plans to sell its Xen management tool software, XenOptimizer. “We’re parking that for now,” Crosby said. There already are several management tool companies with which customers are comfortable, and those customers “don’t want to see XenSource going head-to-head with those guys,” he said.

…

Virtual Iron plans management tools
Virtual Iron doesn’t share XenSource’s reticence for management software. With the upcoming version 3 of its software, it will let Xen customers manage Xen virtual machines. For example, it can move virtual machines from one physical computer to another and restart virtual machines when a computer fails.

The Lowell, Mass.-based company plans three versions of its product. The Community Edition will be available freely under the same General Public License (GPL) as Xen itself, includes basic Virtual Iron extensions.

The Professional Edition will be free and supports management of a single server. The Enterprise Edition will let customers manage virtual machines running on multiple computers, with prices starting at $1,500.

Beta testing for Virtual Iron 3 on Linux will begin in July and on Windows in September. Both versions should be generally available before the end of the year, Thibault said.

The strategy marks a dramatic departure for Virtual Iron. Previously, the company had billed its software as providing a way to use InfiniBand high-speed links to join several low-end servers into what amounted to single multiprocessor system.

“Trying to sell InfiniBand into enterprise datacenters was, to say the least, a real challenge. We were spending more time selling InfiniBand than our own product,” Thibault said. “What got lost in translation was we had built a very full-featured management platform.”

Is Virtualization the miracle cure for software set-up?

by Leave a Comment

Stephen Shankland at News.Com reports:

Most talk about virtualization these days centers on using server hardware more efficiently. But the technology also has the potential to ease another headache: software installation woes.

 

Today, administrators installing software typically must ensure beforehand that it’s certified to run with their particular hardware and operating systems, then configure and optimize it afterward. The hidden benefit from virtualization is that users can unpack a ready-to-run collection of software components–operating system and all–and drop it onto a fresh, empty partition of the computer called a virtual machine. No muss, no fuss, no driver updates, no configuration file tweaking, no conflicts with other software.Virtualization essentially lets the companies selling the software handle the tricky part also provides a clean slate for installation.There’s one problem, however: Some software licensing plans aren’t designed to accommodate such schemes, though that could eventually change.One convert to the approach is Open Xchange, a server software company that lets customers download its software packaged into a virtual machine so they can quickly get to the evaluation stage. Within the next six months, the company plans to release software for production use, not just testing, said Dan Kusnetzky, executive vice president of marketing strategy. “We send an image that (has) a complete stack of software preinstalled, set up and ready to go,” Kusnetzky said. “We felt it would be an advantage in the competitive marketplace,” he said, because without the virtual machine approach, “it took a level of expertise to install it.” Representatives from three powers in the virtualization realm–EMC subsidiary VMware, its XenSource with the open-source Xen software and Microsoft with the proprietary Virtual Server software–all believe at a minimum that the idea has potential. But it’s VMware, which leads the virtualization market, that’s working hardest to make virtual machine-based installation a reality–and to make its underlying virtual machine technology the foundation of choice. It has a Web site where people can download sample virtual-machine-based packages from Oracle, IBM and others. “The reasons it’s going to become mainstream is you can now package your application with the operating system it really wants. You get the exact patch level and everything in the OS that you want,” said VMware President Diane Greene. And it’s particularly useful for small software companies that don’t have engineers to support a wide variety of systems. “They don’t have to necessarily port their software to every possible operating system and every possible version of the operating system.” In recent months, VMware started offering two free ways that customers can try out virtual-machine-based software packages, which it calls virtual appliances. First came VMware Player in 2005, good for desktop applications, such as an isolated partition for safely surfing the Internet. In February came part two: VMware Server for server tasks. Xen programmers are currently stabilizing their core virtual machine software, but virtual-machine-based installation will happen with Xen, too, predicted Simon Crosby, XenSource co-founder and chief technology officer. “That’s equally possible in Xen…I definitely think it’s going to happen,” Crosby said, though he acknowledged Xen doesn’t yet have VMware’s mature virtual machine management software or established presence at many customer sites.

Licensing lumps

 

Not so fast, cautions Illuminata analyst Gordon Haff. “This is a direction, but not a near-term mainstream change in the way that everyone installs their applications,” Haff said. “There are too many details to work through. Licensing is one issue.” The licensing hurdle stems chiefly from the fact that the installation method requires the inclusion of an operating system, and although software companies might delight in distributing them willy-nilly, operating system companies are more finicky. Microsoft, for example, permits only evaluation copies of Windows to be distributed, and then only within a company and only to test and evaluate software, said James Ni, group product manager for server virtualization at Microsoft. “Currently there is no redistribution of the Windows Server operating system,” Ni said. Right now, the virtual installation idea is about testing software rather than full-on production use, so the evaluation software approach is appropriate, Ni argued. He’s not alone in his assessment. “I would expect this to be primarily about experimentation,” said Forrester analyst Frank Gillett. Ni didn’t close the door to virtual-machine-based software sales. Market forces dictated major changes to Microsoft licensing policies before. For example, Microsoft in 2004 began charging the same price for a dual-core processor as for a single-core processor, and in 2005 started permitting customers with one license for Windows Server 2003 Enterprise Edition to run as many as four copies on a single server partitioned with virtual machine software. But Microsoft’s policy is an impediment to VMware’s aspiration. Greene sees companies distributing virtual-machine-based software internally today and expects customers will eventually buy it that way, Greene said. “Microsoft is not letting their operating system be used in this model,” Greene said. And though it’s had a more permissive position in the past, it has backed off that stance: “Microsoft did not renew our license to (redistribute) Windows.” Open-source software, of course, has fewer restrictions. “Linux makes it easy,” Gillett said. …

Not just the operating system

Microsoft, Xen and VMware virtualize a computer’s hardware. But some companies tackling the problem at a higher level are offering a different revamp of software installation. SWsoft sells a product called Virtuozzo that essentially virtualizes the operating system rather than the underlying hardware. That lets several programs run at once in separate zones on one instance Linux or Windows. Sun Microsystems has taken the same approach with its “containers” technology in Solaris 10. “We have templates for close to 100 different solutions and applications for various configurations,” said SWsoft Chief Executive Serguei Beloussov. “When you apply a template to a certain virtual private server (a partition), this solution will immediately become available.” …Softricity is another company that tries to break the hard link between operating system and applications. Its software first captures all the modifications a software package makes to Windows, letting companies store employees’ configurations on a central server rather than directly modifying a PC and potentially causing conflicts among different programs. “The applications are no longer bound to the operating system,” said David Greschler, co-founder and vice president of corporate marketing. That lets administrators quickly set up new PCs or update existing ones, he said. It also means employees can move from one PC to another without disruption, because their software is automatically enabled when they log on to a new PC.

Different standards

Yet another complication comes from the fact that VMware, Xen and Microsoft use a different file format for their virtual machines. In August, VMware began trying to standardize its format. That was shortly after Microsoft began offering royalty-free licenses to use its format, called Virtual Hard Disk. And Xen uses a third format, XVM. Barriers between these formats are not insurmountable. For example, XenSource licensed Microsoft’s VHD and will offer the ability to import virtual machines created with Microsoft Virtual Server, Crosby said, and VMware shared its format as well. At the same time, VMware offers support for that feature with its Virtual Machine Importer software. Insurmountable, yes, but barriers nonetheless. “It will tend to retard the movement toward a standard hypervisor level that just sits on top of x86 hardware,” Haff said, adding that low barriers would mean customers could more easily substitute one virtualization company’s product for another. “It is not in VMware’s (or Microsoft’s) business interest to be able to have someone’s free, native hypervisor just slip in to replace ESX Server.” Another hitch stems from cultural obstacles to virtualization in general, Red Hat Chief Executive Matthew Szulik said. “The customers I’ve talked to over the last six months are challenged by the human issues: How will they deal with the sharing of physical resources across the enterprise? We’ve all gotten conditioned to having our own server environments,” he said. Virtual installation will happen, but XenSource’s Crosby understands the change won’t happen overnight, “I think it’s going to be a fairly profound change for the industry to get there.”

Red Hat Isn’t Exhibiting ‘Xen’-Ophobia

by Leave a Comment

Quoting Jason Brooks from eWeek:

Red Hat’s announcement March 14 of its integrated virtualization push, starring Xen, didn’t take anyone by surprise: Red Hat, along with just about everybody else, has been tooting the Xen horn ever since the fledgling open-source virtualization technology began grabbing headlines almost a year ago.
…
The trouble is that Xen is somewhat early on in its development, and the high rate of change in Xen’s code base will keep the technology out of the mainstream Linux kernel for some time.

Red Hat has and will continue to chart its own course with respect to the kernel, diverging from the mainstream where and when appropriate, but Xen’s potential will remain somewhat stunted for as long as it remains in heavy flux…

I’d like to see Red Hat add to its virtualization agenda the OpenVZ project—a GPL’d code base born of SWsoft’s 5-year-old commercial Virtuozzo product, which itself is roughly comparable to the containers in Sun Microsystems’ Solaris 10…

 OpenVZ, which also is vying for inclusion in the mainstream Linux kernel, would complement Xen well and has impressed me in the initial testing I’ve conducted.

Ultimately, it might make the most sense for Red Hat to deploy both Xen and OpenVZ. The complementary technologies would be a good counterbalance to the Xen/container combo I expect to see eventually in Solaris…

Quoting from the Red Hat official announcement:

Red Hat, the world’s leading provider of open source solutions to the enterprise, today formally announced its ‘Integrated Virtualization’ strategy. During a launch today in San Francisco, company executives detailed plans for creating a Red Hat virtualization environment and working with partners such as AMD, Intel, Network Appliance and XenSource to simplify virtualization deployment for customers.
…
Red Hat will tightly integrate virtualization capabilities with its operating system and ensure all aspects of the Red Hat Enterprise Linux platform, from management tools and installation to software management, will enable customers to deploy virtualized environments easily and effectively.
…
This month Red Hat will make Fedora Core 5 available, which will contain a preview of Red Hat Enterprise Linux virtualization technology. In the summer of 2006, Red Hat will make Virtualization Migration and Assessment Services available along with an Enterprise Virtualization beta. Red Hat Enterprise Linux v. 5, scheduled for general availability by the end of 2006, will feature fully integrated virtualization…
