hey I arrived on the scene way after Plymouth Rock 2nd level systems are great for testing, buidling, servicing, playing, etc. And training. I do a lot of my builds and service from 2nd level guest. Also for staging new versions, etc. Due to double SIE emulation do not run 3rd level guest in production; i.e. do not use a 2nd level vm system as a home for production linux servers of any sort. linux production servers belong under vm in an lpar production = any services wanted by anyone but you David
