The Promise of Plug-and-Go Virtualization
Demand for the stand-alone hypervisor product would depend on what the user's application needs were, Jaffe said, noting that the current approach of integrating the hypervisor as part of Linux worked fine for the conventional compute model, where there was a big system and a stack, and would continue to work fine there. "But then, if you have something like the all-in-one appliance-like framework or any of the other different emerging models of computing, for that you sometimes want a tighter form factor that you can just plug it in and go. So we are trying to address these different market segments," Jaffe said.Asked to what extent or how Novell plans to make SLES 11, the next version of its server operating system, more roles-based, as Microsoft has done with Windows Server 2008, Jaffe said the way he looked at this was that there was the core operating system and the management system. In the Linux world, and probably in the SUSE Linux Enterprise 11 time frame, the operating system itself would manage more core system resources and be less of an application manager, while the broader management system would be providing the other capabilities, he said. "Do I agree with Microsoft that roles-based management is an important paradigm? Absolutely. But from a function placement perspective, I would put it more in the management system rather than in the operating system. With Microsoft's monolithic integrated approach, you sometimes can't cull that out separately," he said.
While Novell believes that the target market for virtualization is "everyone," the appropriate form factor would differ based on whether the user was running a conventional stack, a tight appliance or a turnkey appliance that did not require all of the overhead and configurability, he said.
