There have been many changes in the market and technology since Citrix acquired XenSource and a major stewardship stake in the Xen open source hypervisor four years ago. Red Hat’s 2008 Qumranet acquisition and subsequent push behind the Linux-integrated Kernel-based Virtual Machine (KVM) hypervisor has added to the disruption. One thing, though, remains the same: the intense competition among these open source hypervisors in the enterprise market.

One of big stories out of the Open Source Business Conference this week was Microsoft’s announced support for the CentOS community Linux distribution, a free clone of RHEL that nonetheless enjoys significant enterprise and cloud computing use, as we’ve covered extensively, including a special report that is currently being updated, in part, with a new survey.
This is not the first time MS has displayed love for unpaid, community Linux, given its 2009 contribution of GPL-licensed code to the Linux kernel. This was significant in that it was contribution and participation by Microsoft in the Linux kernel, beyond one of its partner’s Linux distributions, such as the case of Novell and SUSE Linux and more recently, Red Hat and its RHEL for mutual, customer-demanded virtualization support (451 subscribers) between Microsoft and Red Hat.
It seems Microsoft understands that unlike pirated Windows, which it considers a loss, the use of free, unpaid Linux — particularly by large enterprise, government and other organizations — is a big opportunity for it.
True, use of community Linux is typically driven by cost savings and the capability of sizable organizations to self-manage their Linux servers, often involving no payment. However, our research indicates there is often is still a need for higher level support and, more commonly, the ‘insurance factor’ of having a commercial vendor behind your infrastructure software so you, or your boss or board, have someone to call or blame if things go wrong. Microsoft is capable of supporting CentOS in both cases of technical support and being the insurance for an organization. It will be interesting to see the kind of reaction and traction the company gets from customers, presumably Windows shops, running CentOS.
It was only a couple of years ago we were writing about the death, and ongoing life of CentOS.
Today, it continues to be one of the most fascinating open source software projects in that it has no formal commercial backer, not even a foundation, but yet benefits from a solid, dedicated development team that continues to push the OS forward. We, along with Microsoft, continue to hear about use of CentOS increasingly in cloud computing, where it can be used, often free of charge, to add, subtract, scale and scrap as needed. It is, like other Linux distributions, also popular among hosting and other service providers, who again are primarily building public, private and hybrid cloud environments and ecosystems.
This is why again it is very interesting to see Microsoft supporting CentOS with HyperV and Windows. It’s not the first vendor to do so, as server giant HP has supported CentOS, Debian and other community distros to some extent in its server and support offerings. Microsoft’s CentOS support is certainly another example of how the landscape and market for various Linux distributions and operating systems in general is currently undergoing disruption.

Reaction to Microsoft’s Linux code release
There was a mixed reaction to Microsoft’s release of Linux code, much of it was positive although the company was also criticized for serving its own interests. Linus Torvalds defended Microsoft’s actions. See this post for more on that. Meanwhile it was also widely reported that Microsoft’s apparent altruism was in fact the result of a violation of the GPL. See this post for a round-up on that subject.
Elsewhere Stephen Walli pointed out that the LinuxIC code is not Microsoft’s first contribution under the GPL, while Microsoft made sure it was not the last by contributing a plug-in for Moodle under GPLv2.
Microsoft also dismissed Red Hat’s demands that it should “pledge that its patents will never be used against Linux or other open source developers and users”.

July 24th, 2009 — Linux, Software
Earlier this week Microsoft announced that it was contributing driver code to the Linux kernel under the GPLv2, and we published a CAOS Theory Q&A to discuss the implications. It has subsequently become clear that there were two important questions that were not answered by our Q&A:
Q. Is this a donation, or an obligation?
A. In discussing the motivations for the Linux Integration Components (Linux IC) release, Microsoft cited enhancing the performance of Linux as a guest operating system where Windows Server is the host, and that the GPLv2 is “the Linux community’s preferred license”.
An alternative viewpoint began to emerge that suggested that perhaps Microsoft had little choice in the decision to release the code, however. It started with the publication of a post written by Stephen Hemminger, a principle engineer at Vyatta, which stated:
“This saga started when one of the user’s on the Vyatta forum inquired about supporting Hyper-V network driver in the Vyatta kernel. A little googling found the necessary drivers, but on closer examination there was a problem. The driver had both open-source components which were under GPL, and statically linked to several binary parts. The GPL does not permit mixing of closed and open source parts, so this was an obvious violation of the license. Rather than creating noise, my goal was to resolve the problem, so I turned to Greg Kroah-Hartman.”
Kroah-Hartman runs the Linux Kernel Driver Project and is working with Microsoft to introduce the Linux IC code to the Linux kernel. He appeared to confirm Hemminger’s perspective when he wrote “Steve gives a little more of the backstory of what caused me to start talking to Microsoft in the first place,” and then told Mary Jo Foley that her suggestion that “Hemminger is claiming Microsoft put the LIC code under the GPL because it was in violation of the GPL” was “accurate”.
Cue stories such as “Linux community pushed Microsoft to hand over its code” and “Microsoft opened Linux-driver code after ‘violating’ GPL“.
Before commenting on these stories I took the opportunity to speak to Sam Ramji, who seemed genuinely surprised by the perspective that the driver code had violated the GPL and maintained that he was not aware of the account provided by Hemminger prior to its publication.
The two viewpoints are not necessarily mutually exclusive. In his exchange with Foley, Kroah-Hatmann notes that he “didn’t have to ‘suggest'” that Microsoft was in violation, he “only had to merely point out the obviousness of the situation”.
Additionally, Vyatta’s vice president of strategy and marketing, Dave Roberts, has noted that “nobody ‘accused’ anybody of anything. Stephen merely called the situation to Microsoft’s attention… There were no threats, no screaming, no broken fingers, no frothing at the mouth. Just a few calm phone-calls placed behind closed doors, out of the limelight and media focus. And that was that. Microsoft noodled on things. And then it decided to open source the drivers and contribute them to the kernel.”
I also put it to Ramji that if, *hypothetically*, Microsoft were to have discovered it was inadvertently in violation of the GPL, then from a PR standpoint, the company would have much more to gain by being seen to have responded appropriately than by trying to cover it up. He agreed.
(And I don’t think this can be understated actually, if you consider what the open source group within Microsoft is trying to achieve you begin to understand why they would be hyper-sensitive to the fact that trying to claim credit for something they didn’t do would be counter-productive).
Anyway, Ramji has subsequently posted his views on the issue, including:
“Microsoft’s decision was not based on any perceived obligations tied to the GPLv2 license. For business reasons and for customers, we determined it was beneficial to release the drivers to the kernel community under the GPLv2 license through a process that involved working closely with Greg Kroah-Hartman, who helped us understand the community norms and licensing options surrounding the drivers.
The primary reason we made this determination in this case is because GPLv2 is the preferred license required by the Linux community for their broad acceptance and engagement. For us to participate in the Linux Driver Project, GPLv2 was the best option that allowed us to enjoy the tremendous offer of community support.”
Q. So was Microsoft in violation of the GPLv2?
A. Of course, “not being accused of being in violation of the GPL” is not the same thing as “not being in violation of the GPL” but it is not completely clear whether that was actually the case.
Over on Cnet, Gordon Haff got some more technical details from Hemminger:
“According to Stephen, the issue revolves around a feature of the Linux kernel called EXPORT_SYMBOL_GPL that allows for interfaces to be marked as only available to modules with a GPL-compatible license. From Stephen’s perspective, Microsoft’s proprietary code had to use some of these interfaces that ‘the kernel did not want to offer to non-GPL [code].’
If that all seemed a bit geeky technical, well it is. Very possibly a violation of the GPL but hardly one that is simply flagrantly flouting the law.”
UPDATE – The Software Freedom Law Center’s Bradley Kuhn has told SDTimes that Microsoft *was* likely in violation of the GPL:
“It seems to me that Sam [Ramji] is likely correct when he says that talk inside Microsoft about releasing the source was under way before the Linux developers began their enforcement effort,” said Bradley Kuhn, a policy analyst and tech director at the SFLC.
“However, that talk doesn’t mean that there wasn’t a problem. As soon as one distributes the binaries of a GPL’d work, one must provide the source for those binaries, so Microsoft’s delay in this regard was a GPL violation.”
However, Ramji continues to deny that a GPL violation was the significant issue. “Greg’s coaching on how to get it contributed was invaluable, but it was not the original driver of our plan or decision,” he told SDTimes. “That’s the beauty of the real world. Different people have different perspectives, and that is what causes them to act. We appreciate Greg’s coaching regardless of his motivation.” – UPDATE
2ND UPDATE – Sam Ramji has once again denied that Microsoft violated the GPL. In a podcast published at Network World he points out (from 15.30) that the code did not statically link to libraries in the Linux kernel, but to the header files, and that Linux developers are split on whether that constitutes a violation of the GPL. “The act of compiling to a header file doesn’t generate a GPL obligation to my knowledge, that was never a consideration in our process.” – 2ND UPDATE
In his initial blog post, Hemminger stated that the saga was started by an inquiry about supporting Hyper-V network driver in the Vyatta kernel, presumably this one, from March, when Hemminger has said the issue was bought to his attention. Hemminger’s response at the time is that “Msft hyper-v driver is not open source, and redistributing it would require agreement with them”.
The driver cited in that query would appear to be the original Linux Integration Components for Hyper-V, which were released in September 2008, the same components that The H reported were previously withdrawn from release candidate distribution in July 2008 for a licensing review.
As Patrick O’Rourke noted at the time, “Licensing is tricky when open source and proprietary software are packaged.” No kidding.
A quick note while we are on the subject of timing, Hank Janssen says he proposed that Microsoft open source Linux IC driver code in October 2008. Sam Ramji told me Microsoft started seriously considering it in January this year and first heard from Greg Kroah-Hartman in May.
While Hemminger started that Microsoft’s release of the code under the GPLv2 “”took longer than expected”, Gordon Haff notes that Hemming “said that he first discovered this in March, so four months is actually fairly rapid resolution as such things go in large companies.”
Q. Anything more to add?
A. Probably. If anything new does arise, we’ll post details here.

July 20th, 2009 — Licensing, Linux, Software
Microsoft has announced that it is to contribute code to the Linux kernel development effort under the GNU General Public License (GPL) v2. What on earth does it all mean? Here’s our take on the situation. With thanks to Jay Lyman for his contribution to the following:
Q. This is a joke, right?
A. Not at all, although if any announcement is better suited to the image above, we can’t think of one. Microsoft has announced that it is going to contribute code to Linux under the GPLv2.
Q. What code is Microsoft contributing?
A. Microsoft is offering 20,000 lines of its own device drivers to the Linux kernel that will enable Linux to run as a guest on its Hyper-V virtualization technology. Specifically, the contributed loadable kernel modules enable Linux to run in ‘enlightened mode’, giving it efficiencies equivalent to a Windows virtual machine running on Hyper-V.
Q. Why is Microsoft doing this?
A. Red Hat and Novell’s Linux distributions already support enlightened mode, thanks to the development work done by both in partnership with Microsoft. One benefit for Microsoft of contributing to the kernel is that it reduces duplication of effort and the cost of supporting multiple, unique implementations of Linux. Once the code has been accepted into the kernel, Microsoft will use the kernel tree code as the basis for future virtualization integration development.
It also means that community Linux distributions will be able to use the code, which opens up more opportunities for Microsoft in the hosting market, where adoption of community Linux distributions such as Ubuntu, Debian and CentOS is significant. It also therefore slightly strengthens the challenge those community operating systems can make to Red Hat and Novell, which are more direct commercial challengers to Windows.
Make no mistake about it, Microsoft’s contribution is driven by its own interests. While it must serve and respond to enterprise customers that continue to drive the use of multiple operating systems and mixed environments, Microsoft also benefits by differentiating its Hyper-V virtualization technology from virtualization leader VMware. We believe Microsoft sees an opportunity to make virtualization with Windows more Linux-friendly than VMware.
Q. What’s in it for Linux?
A. The interoperability benefits previously reserved for ‘approved’ Microsoft partners will now be available licensed under the GPLv2, and available for all Linux distributions – commercial or community – without the need for a formal partnership.
The contribution of device drivers to the Linux kernel as been a sticking point for the Linux development community in the past as developers have struggled to encourage vendors to contribute driver code to the kernel. Microsoft is therefore setting something of a precedent and could encourage other vendors that have been reticent to contribute their drivers to do so.
The seal of approval Microsoft has given to the GPLv2 is also not to be overlooked. If Microsoft can find a way to contribute to Linux projects, many other organisations may also be encouraged to do so.
Q. I guess Linux is no longer “a cancer” then?
A. Exactly. Back in 2001 Steve Ballmer told the Chicago Sun-Times* “Linux is a cancer that attaches itself in an intellectual property sense to everything it touches. That’s the way that the license works.”
Reviewing the statement in the context of today’s announcement demonstrates how much progress Microsoft has made in the intervening years to understand open source licenses. Contribution to Linux, or to any other project under the GPL, would have been unthinkable at the time, and is still barely believable today. The announcement is likely to challenge perceptions of Microsoft’s strategy when it comes to open source, Linux and the most popular open source license.
*The original article is no longer available online. Plenty of references are still available, however.
Q. What does this say about Microsoft’s overall strategy towards open source?
A. The contribution is a significant sign that Microsoft is now prepared to participate with open source projects on their own terms by using the chosen license of that project and making contributions directly to the chosen development forge of that project. Microsoft continues to use its own CodePlex project hosting site for code releases, but if an existing open source project uses SourceForge then Microsoft has acknowledged that the best way to engage with that community is on SourceForge. Don’t expect this to be the last contribution Microsoft does under the GPL.
Microsoft is now becoming more proactive in how it engages with open source under a strategy it describes as ‘Open Edge’ (which we have previously mentioned here and here. Whereas Open Core is used by commercial open source vendors to offer proprietary extensions to open source code, Open Edge is Microsoft’s strategy to encourage open source development and application deployment on top of its suite of commercial software: Windows, Office, Exchange, Sharepoint, SQL Server etc.
The Open Edge strategy is rooted in attempting to ensure Microsoft’s commercial products continue to be relevant to the ecosystem of developers and partners that the company has attracted to its software platform. It is also a continuation of the realization that if customers and developers are going to use open source software, Microsoft is more likely to retain those customers if it helps them use open source on Windows et al.
For more details on Microsoft’s strategy towards open source, its partnerships with open source vendors, and its contributions to open source projects, see The 451 Group’s formal report on the contribution to Linux (the report will shortly be available via this link ).
Q. How is the contribution to the Linux kernel being handled?
A. The contribution is being made via an alliance with the Linux Kernel Driver Project and its maintainer, Greg Kroah-Hartman, who will steward the contribution into the Linux kernel code base. (Greg has a post up about it here).
Q. What are the intellectual property issues?
A. The copyright for the code will remain with Microsoft, with the contributor credit going to its engineering lead, Hank Janssen, group program manager at Microsoft’s Open Source Technology Center.
Q. And patents?
A. If we were putting money on the most likely conspiracy theory to emerge in response to this news it would be that this is a Trojan horse and Microsoft is contributing code to Linux that it will later claim patent rights over. Whether that is even theoretically possible depends on your understanding of the GPLv2.
The GPLv2 contains an implicit patent promise that some would say makes a Trojan horse impossible. However, the FSF obviously thought it necessary to introduce a more explicit patent promise with the GPLv3 to remove any doubt.
Ultimately this is a question for a lawyer, or an eloquence of lawyers (yes it is ironic, apparently). In the meantime, it is our understanding that Microsoft’s understanding is that contributing code using the GPLv2 includes a promise not to charge a royalty for, or assert any patents covering, the code being contributed.
Q. What about Microsoft’s prior claim that Linux infringes its patents?
A. Microsoft really dropped the ball on its communication of the suggestion that free software infringes over 200 of its patents, and tensions with free and open source software advocates are likely to continue to be tested by Linux-related patent agreements, such as the one struck with Melco Holdings last week, which have driven scepticism and mistrust of Microsoft among some key open source supporters.
Absent the company giving up on software patents altogether, we believe that in order to convince those FOSS advocates that it is serious about co-existence, Microsoft needs to find a way to publicly communicate details about those 200+ patents in such a way that is not seen as a threat and would enable open source developers to license, work around, or challenge them. We also believe that the company is aware of this, although finding a solution to the problem will not be easy. But then neither was contributing code to Linux under the GPLv2.
UPDATE – It has subsequently become clear that there were two important questions that were not answered by our Q&A. Those have been covered by an addendum – UPDATE.

February 16th, 2009 — Linux, Software
More than two years since Microsoft persuaded Novell to enter into an interoperability agreement concerning Linux and Windows, it has finally got Red Hat to talk interoperability.
The agreement does not appear to be a repeat of the one Microsoft struck with Novell, however. I’m still taking in the details but one element stands out:
That is a significant statement given Red Hat’s insistence that an intellectual property agreement was not necessary to create interoperability between Linux and Windows, and Microsoft’s former claim that patent indemnification was a prerequisite for collaboration.
Under their agreement to work together Microsoft and Red Hat will provide testing, validation and coordinated technical support for mutual customers using server virtualization. Red Hat has joined Microsoft’s Server Virtualization Validation Program, and Microsoft is now a Red Hat partner for virtualization interoperability and support.
According to the agreement: “Once technical validation testing is complete, customers with valid support agreements will receive coordinated technical support for running Windows Server 2008 virtualized on Red Hat Enterprise virtualization, and for running Red Hat Enterprise Linux virtualized on Windows Server 2008 Hyper-V.”
There is no Linux-support coupon scheme, although that was exclusive to the Novell-Microsoft agreement anyway, and no patent or intellectual property agreement either.

We’ve sure seen some interesting maneuvering on virtualization recently by the major OS players Microsoft, Novell and Red Hat. While Red Hat sought a bigger stake in virtualization with its $107m Qumranet acquisition, Microsoft and Novell were busy releasing the first fruit of their interoperability lab – native support and performance for Novell’s SUSE Linux as a more welcome guest OS on Microsoft’s Windows Server 2008 Hyper-V.
It’s interesting to see Novell so vigorously supporting Microsoft’s Hyper-V, and this may be part of what accompanies the partnership with Microsoft and its purchase of SUSE Linux coupons, but Novell is certainly not alone in its Hyper-V support. This is also a logical place for Microsoft and Novell to build on their promise of Linux-Windows interoperability. However, it may raise questions about the impact to the other virtualization technology that has figured prominently in Novell’s SUSE Linux for the last couple of years: Xen. Novell insists Xen is its hypervisor of choice and it remains committed to the virtualization software and project. In fact, as Novell seeks to make good on its promise to deliver some of its collaboration with Microsoft back to the greater Linux community, Xen may very well be the place it does so. At the same time, when asked about Red Hat’s Qumranet buy, one Novell executive responded by touting Xen’s ecosystem, which has indeed matured dramatically since Novell first included it in its enterprise Linux more than two years ago.
Red Hat has also affirmed its commitment to supporting Xen as well, even while it was announcing its $100m+ investment in, ahem, another virtualiation technology and company. Nevertheless, Red Hat also realizes the time, effort and maturation that it has taken for Xen to get where it is. In fact, that was one of the drivers for the Qumranet deal, according to one company official who says Red Hat knew it had to get something that was already underway, yet could speed and spread Red Hat’s presence in virtualization. Qumranet and KVM may be the ticket, but the lone Linux vendor will have formidable challenges in its OS rivals Microsoft and Novell, as well as the ‘virtualization only’ vendors (VMware and Citrix) that Red Hat is aiming at with its new acquisition.
