VMware’s clause against competitive products at VMworld 2009 annoyed the hell out of Microsoft, and the company doesn’t intend to sit idly by as thousands of potential Hyper-V users convene in San Francisco. Sure, they’ll follow the show rules; Microsoft’ll have a 10-by-10 booth on the show floor and they won’t demonstrate the new features and capabilities in Hyper-V, which’ll be available in Windows Server 2008 R2 in October. But’ll they talk to attendees about Hyper-V and undermine VMware’s Stalin-esque policy of keeping the opposition out? You bet. “When we saw the clause we called [VMware] to check on what we could do. We are only allowed to show products that complement VMware, so we won’t be doing any product demos,” said David Greschler, director of virtualization and management marketing. “But we will be there at the sessions at VMworld and we will be twittering (@MS_Virt) during the show, which is no longer an industry show. It is a VMware show.”
