Longhorn Server Will Stress Virtualization
Rob writes in with an article from CBROnline based on an interview with Microsoft's UK server director. He says the timing of the release of the next version of Microsoft's server OS, dubbed Longhorn, depends on the company getting virtualization ready to go. Microsoft has apparently decided to embed its hypervisor technology into Windows, an OS-centric approach to virtualization shared by XenSource Inc., its open-source rival and partner. This contrasts with the model of virtualizing the hardware layer being pursued by VMWare. The Microsoft spokesman is coy about a release date for Longhorn, saying it could be earlier or it could be later (but it should be in 2007).
``And, I believe that Linux is the "better" OS in that the kernel has gone through a more stringent review process.''
Moreover, you can easily strip Linux down to just the bare minimum needed to run the hypervisor. No need to waste several hundred megabytes of RAM on features you won't be using.
Please correct me if I got my facts wrong.
