Can you tell us about the characteristics of the Xen community and how XenSource works with them?

Are you platform-agnostic? Crosby: We’re basically cross-platform from a processor architecture and operating system perspective, because with hardware virtualization we get to virtualize the entire legacy OS and Windows world. Any OS vendor can utilize Xen and deliver a paravirtualized high performance version of their software that would take advantage of Xen. Xen today runs on x86, x86_64, IA64 and Power 5 processor architectures, and Sun is rumored to be porting Xen to SPARC. GCJ: Any upcoming milestones for XenSource that we should be aware of?
