Good and well written post by Mark Duszyk (thank you) – AIX rules 
After installing a pair of LINUX “hosts” in fully virtualized lpars I was sent for LINUX training. While being trained, I soon discovered the beauty and elegance of VMWARE. Upon my return from the training and with the “help of my friends” I set one RedHat quest on one WMWare cluster (DEV/TEST) and copied it to the other two (PRODUCTION clusters in two data centers). From now on, to build LINUX HTTP/TomCat box all that needs to be done is to clone the copy! By the way, before the copies were made, we disabled the networking services on the “gold” copy. One has to spend just a few minutes in front of a WMWARE to understand its power, elegance, and simplicity. Yes, here there is no more LINUX but on VMWARE.
Yes, I can hear it. Your voice is laud and clear. “How could I do that to AIX?” Why? Because my love is not blind; I want AIX to be the best OS there ever been. I do not want AIX to STAGNATE! I want to retire doing AIX!
