In one scenario you have a bunch of Linuxen running on z/VM and you have z/OS, but you don't use it with z/VM. You realize that you could speed up or reduce the cost of z/OS app development if you didn't have to devote so much h/w to it. But you're not sure you want to get into that game, so you add a CP to your z/VM-mode LPAR. Now you can create z/OS guests and virtual sysplexes without the additonal administrative burden of a second z/VM LPAR. And then there are those who have been using z/VM with z/OS guests for many years who want to dip their toes into Linux. Just add an IFL or two and you're off to the races. (There are z/VM licensing cost issues to deal with, of course, but such problems have solutions.) Alan Altmark z/VM Development IBM Endicott
