Mike Myers: I am newbie on linux and Z/VM too. After one year and half , I have installed VM5.4 with Dirmaint, Racf . I am very proud of myself. It also proves that this system isn't hard to learn and build.
My experience is that : Go to Share Conference---z/VM sessions first, Second start to build while you learn . The zVM and Linux on z the Virtualization cookbook for sles 10 is the wonderful book for us to follow. If you find some errors, VMgroup and Linux group is the good place to post.

I am a Linux newbie and am trying to accelerate my learning experience. Ubuntu has been helpful with that. Some of the stuff I guessed I had to do to try and "fix" zLinux show me that I'm actually learning the command line interface <gasp>. My long-term objective is getting zLinux running in an LPAR on a zSeries box at my current client's. I'm using Hercules to give me some experience with zLinux's capabilities before I try to start it there. Since I have been using Ubuntu to get my "Introduction to Linux", I was kind of thinking that I might be able to offer a similar environment to the main-framers I am working with when I presented them with zLinux. I guess the best strategy is to get them some experience with Ubuntu or an equivalent distro (in what I'll call "mixed mode" - using both commands and a GUI) and then show zLinux to the server folks when I get it going.
