In contrast to VMware, where code that emulates legacy hardware runs in the hypervisor, the code for Windows Server 2008 with Hyper-V resides within the virtualization stack, according to the Microsoft spokesman. Since customers are already familiar with the Microsoft driver model, this is supposed to allow them to leverage the hypervisor more readily.
Does all this mean we've turned a corner in the virtualization market and that innovation will foster a new wave of competition? Not necessarily, warns industry analyst Marc Staimer, president of Dragon Slayer Consulting. "The data center guys will just wait and see what Microsoft delivers versus what they say they will deliver," he said. That may be a prudent tack where virtual claims are concerned.
