Microsoft’s head of server virtualization says he doesn’t mind playing catch-up to VMware in the hypervisor market. Microsoft’s Mike Neil notes that Hyper-V’s market share is growing faster than VMware’s. Microsoft will maintain a limited presence at VMworld in San Francisco Aug. 30 to Sept. 2. Microsoft and its virtualization partner Citrix have repeatedly butted heads with VMware, notably by pulling out as sponsors of last year’s VMworld conference after claiming that the company unfairly limited competition at the show.”]
