They (x86 boys) want to roll into IBM territory (Hypervisor in Power5
boxes).

nonsense. virtualization was popular in the mainframe world precisely
because mainframes were a huge investment. of course it made sense to
virtualize them, purely in order to make time-slicing more seamless.

killer micros changed all that - a very fast cpu now costs 3 digits,
not 7, and virtualizing it doesn't make much sense, at least not
virtualizing it much. yes, there will probably always be mainframe
recidivists who want to be able to partition a nice 256-core NUMA box
into piddly little chunks for each department (which could have been
bought as separate machines for 99% less cost). but that kind of inane
PHBism will always exist.
