Virtualization is not a solution. It's a small feature.

The problem with salesman is that they act like sound-byte dumb processing machines.
If the current trend was (God Forbid! ) placing Windows Vista on mainframe no matter how dumb, irrational that would be, they would move mountains to make it possible, spend billions, make huge marketing efforts and totally dumb articles to justify the investment ... in a a word ... those who do not understand nothing about computing should not interfere with Technical decisions.
My argument from a long time ago.

The Hype of the moment is Virtualization.
As with everything in technology each case is a different case and in here we can do no more then a generalization to the issues we discuss.
But virtualization is a "nice to have" feature, but that's it, it is simply a nice feature that serves a mid-term purpose. Not a solution.
No matter what the system is a VM Always runs Slower and Less efficiently then the native system.
It simply is a waste of resources and a complete inefficiency increase on any system.
VM's have some advantages like ease to restore system settings.
But nothing that a good backup policy could not make.
Also in the case of running highly secure systems there are in the Linux world far better solution like User Mode Linux and chrooted applications, not to mention native SELinux and AppArmor ...
Remember folks, some years ago VM's where not even possible as they would have slumped the systems they were running due to overhead.
Only now they can run at the cost of the very big processing power of current CPU's.

IBM should understand that when a solution is out of date it should be replaced.
But that goes against one of the comments I made yesterday: IBM as this culture with some of it's customers that systems are supposed to last decades. Not in terms of the architecture, but the systems themselves ... ! As if this was possible in IT where things change in a yearly basis ...
This "mentality", this mind set, is usual in managers that are total ignorants about what IT is all about ...
This is a sort of a gathering between ineptitude and the most pure ignorance.
Well, fortunately they will keep spending some hard cash on Linux and that is the good thing in this story.

Regards,
Pedro
