I don't think so Gary. Look at the pure cost of processing resources.
A typical IFL today has what, 500 or so MIPs at a miniumum? That
isn't going to emulate a typical bloated X86 system all that fast,
even given the processing map within virtual machines.
At least in general, it is difficult and expensive to match the pure
processing power of modern x86 systems, even on modern mainframes.
Also, I have doubts that z/VM would do a much better job virtualizing
x86 machines than VMWare does. The x86 architechture is just - wierd. :)

Considering the average CPU utilization for x86 desktop systems
(less than
15% by some estimates), such support could make for a good match;
guest
systems that do practically nothing and a virtualization system with a
remarkable ability to allocate resources among a large number of
guests.

That's what
confuses me- the two platforms, mainframe and x86 are hardly
competitive to each other.
