Gozillion thanks, it's impossible to overestimate the luck of meeting real experts who can explain things in a simple language. God bless this forum :-)

May I ask couple more questions on this:

1.
Clear now. I can guess that productivity of p-Series-type virtualization is better, since there are less layers of software.

But what are the drawbacks of p-Series-type virtualization? What are there things that first type of virtualization can do, but p-Series type of virtualization cannot do?

2. Hmm... You're saying that I can (in principle) move my app (and its LPAR) from box to box easily. And can I (again, in principle) at all decouple my app and my boxes? I.e. have a bunch of IBM boxes and some "hyper-LPAR" that aggregates all of them into one big machine? And my app that runs on that "hyper-LPAR" and doesn't really care whether it in reality executed on box A, box B, or even both boxes A and B? Do people do that?

Thx again
