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

For all of you old timers that have used VM since it landed on Plymouth Rock, 
what are the pros and cons of using a second level VM system?

Thanks in advance.
