I would recommend this... Do your installation on 1st level VM. After that is complete, IPL it on your 2nd level VM. Performance will still likely stink, but at least you'll have a running, er, crawling, system.

I really suspect I did someting wrong on VM side.... which lead RedHat not to behave as well as SuSE... But what? Any kind of advice, somebody? Amicalement/Best Regards...
