For my tests right now, I'm simply trying to get dual Centos up/running,
Based on what you've said, there are errors in what I'm trying to
accomplish. You wouldn't have a few mins to walk me through this would
I'm convinced that this is doable, and that whatever mistakes I've
made are probably subtle/easy to correct.
Do you happen to know of a good tutorial for this that walks through
all the steps.
