Alan - you are missing the point and I believe that Dave already mentioned some of the reasons but I will add mine.
We are a OS/390 shop with ZERO VM skills. The distributed group does not want to learn z/VM for many reasons, among them are the lack of any usable intro/how-to documents to get started with - the existing pubs assume a firm foundation or knowledge gained from attending a class. The OS/390 sysprogs that are assigned to the z/VM + Linux world have this as just another assignment and thus do not have the time to become full fledged z/VM sysprogs and management does not want to hire a z/VM sysprog full time or contract for one. Management has been led to believe that z/VM+Linux is simple and it isn't. SAF was, supposedly like VIF, a simple to use tool but it was to limited to be helpful beyond some very basic functions. If you want z/VM+Linux to be successful you (IBM) need to publish a simple HowTo type document with step by step instructions, with explanation, for setting up and managing this new environment. Or you need to convince management that they need to train/hire/contract for z/VM skills and that they can't assume that the individual(s) will have time to do other z/OS activities if the z/VM+Linux environment is dynamic/active to any degree. -------------------------------------------------------------------- Lionel B.
