It doesn't appear that the author has a very good idea of the basic
concepts
because he makes a lot of basic mistakes.
He apparently thinks that VM is used to "micro-partition" LPARS and refers
to
it as CP/VM, a term I don't remember seeing used. CP-40 etc, but not CP/VM.
He also seems to think that the linux timer pops are the same as i/o
interrupts,
has no idea about paging/swapping ("My main question, however, is how he
got
41,400 instances to fit into a 128 megabyte machine."), keeps refering to
guests
as "ghosts", and such gems as;
"Since each such LPAR is independent of all others, it can run VM
or any other OS, including Linux, separately although each remains
dependent on the underlying hardware and microcode."
As if this is in any way different than any other computing system and is
somehow
a disadvantage of the IBM platform.
And I have only read the first few pages. I am sure that others can find a
lot more
problems with this article.
Big grain of salt!

Anyone seen this?
Aside from some (fairly glaring) technical inaccuracies, I can't see much
I'm qualified to dispute.
