Microsoft’s Favorite Linux Distribution
Both of these management systems allow the management of Windows and both SLES and RHEL, but Microsoft appears to favor the former over the latter. Demonstrating this, the company signed a set of agreements with Novell in November 2006 to work towards better interoperability between Windows and SLES in four areas:
* virtualization * systems management * directory integration and identity * office document formats
The deal, which runs at least until 2012, has been treated with a great deal of suspicion by many people, partly because it can easily be construed as a way for Microsoft to get a “pet” Linux distro which it can control and use to get a better understanding of Linux and customers’ reasons for wanting to use it for its own advantage. The deal includes an agreement for Microsoft to refrain from taking legal action against Novell’s customers for using Linux (which Microsoft claims infringes various of its patents,) and also involves Microsoft making payments to Novell (and therefore indirectly subsidizing SLES.) One way this is achieved is by buying support coupons from Novell, which Microsoft then sells on to its customers at a discount.

and Linspire is already dead.
The other reason for ESX's edge here is that Hyper-V -- as Microsoft certifies -- supports only one version of Linux, Novell's SUSE Linux Enterprise (SLES) 10 Service Pack 1 or 2, in x86 and x64 versions. However, only one virtual processor is supported for each virtualized instance of SLES 10 SP 1 or 2. Microsoft's Connectix acquisition, which brought Microsoft Virtual Server to market, initially supported a vastly wider variety of guests. For Hyper-V support of Linux, Microsoft's relationship with Novell has Microsoft buying hundreds of thousands of SUSE Linux support kits for Microsoft's (and their customers') use.
A lot of matrimony has been witnessed in the recent past on the aisle of open source. How do you interpret the consolidation action around with deals like MS-Novell, Sun-My SQL, Yahoo-Zimbra?
[James M Whitehurst:] I won't pooh pooh anything. That said, not many realize the real essence. The power of OS is in maximizing community and collaboration. Sun controls the major part of development realm. I don't know, in that light, how exactly they make the model work. We are hundred per cent OS that leads to greater strategic clarity.
The idea of economics of abundance again comes to discussion here. We don't control Linux. But getting the constant changes that happen on the development front, as upstream as possible is the real thing. There was once a need for a real-time kernel by banks and financial services customers. Novell already had it but they never got it upstream, so when we did that upstream, they had to abandon theirs. The whole Linux later moved in that direction.
As for what its customers are actually virtualizing these days using the AppLogic tool: Customers can use any Linux with a 2.6 kernel, but CentOS, Fedora, Ubuntu, and Debian are the most popular Linuxes used by AppLogic users, with a smattering of Red Hat Enterprise Linux. So far, no one has deployed on Novell's SUSE Linux Enterprise Server.
To paraphrase from Groklaw the central issue is that Microsoft thinks these papers could prove that Novell sold all of its antitrust claims to Caldera, including two outstanding claims against Microsoft regarding Wordperfect. If Microsoft can prove that, Microsoft would argue that the outstanding claims are kaput, covered by a settlement agreement with Caldera in 2000.
