You are not going to like the answer, Wayne. IBM *will* do personality (zAAP to IFL, zAAP to zIIP, etc.) changes for a price, but they will not allow zAAP/zIIP processors to execute VM or Linux natively. Same reason IFLs cannot run z/OS.

Why would this be useful? I currently have a z9 BC machine with 2 cp's and a zAAP. Due to my workload, the 2 CP's are running around 90% busy, while the zAAP is only running at about 20% utilization. Now my management wants to move workload to Linux. I want to show that Linux on system z is a viable option, but I can't try it out without either 1 - further impact the 2 heavily loaded cp's, or 2 - get 125K from management to get an IFL. However, if I could have share the zAAP with a new zAAP only LPAR, I could run Linux (either bare or under z/VM) on the currently underutilized zAAP. Management sees it is a good thing, then gets addition IFL's. IBM keeps the workload on z, so they (and their shareholders, of which I happen to be) both win.

The only draw back to this is if you have ZAAPs on your machine. I > don't think that zLinux currently dispatches Java workload on ZAAP. No, Linux doesn't dispatch work on zAAPs, and I don't expect it ever will. zIIPs and zAAPs are engines specifically created to help z/OS pricing. Linux runs on IFLs.
