Nice piece. I was surprised that only 30% is virtualized by any hypervisor, thought it would have been alot higher.

Shawn, <br /> There is even a name for it, it is called "VM stall". Many companies started with the easiest application workloads to virtualize, and then are now struggling to virtualize the rest. Meanwhile, I have visited companies that have a "zero x86 virtualization" policy, they do not yet trust the technology. On the POWER and System z systems, virtualization is far more prevalent, but I suspect it is because it has been around longer on those platforms. <br /> -- Tony
