z/OS can now tell you what workload is zIIP and zAAP eligible. Also, z/VM 5.3 can simulate zIIPs and zAAPs without actually having the hardware. All that is perfect for an educational system even if it isn't appropriate for a commercial system.
What you've written here is -- at best -- misleading. The hardware being donated is z900. z/VM will simulate zAAP and zIIP processors *only* on hardware that natively supports those specialty engines. It will not simulate zAAP on z900 nor will it simulate zIIP on anything less than z9.
http://www.ibm.com/common/ssi/rep_ca/9/897/ENUS207-019/ENUS207019.PDF contains the official IBM statement:
"Simulation support z/VM simulates specialty processors for guest virtual machines by dispatching the virtual specialty processors on real CPs. Simulating specialty processors provides a test platform for z/VM guests to exploit mixed-processor configurations. This allows users to assess the operational and CPU utilization implications of configuring a z/OS system with zIIP or zAAP processors without requiring the real specialty processor hardware. This simulation also supports z/VM's continuing role as a disaster-recovery platform, since a virtual configuration can be defined to match the real hardware configuration even when real zIIP or zAAP processors are not available on the recovery system. z/VM simulates specialty processors using real CPs if the underlying hardware is capable of supporting the real specialty processor. zIIPs can be simulated only on System z9 (z9 EC and z9 BC) servers. zAAPs can be simulated only on z9 EC, z9 BC, z990, and z890 servers."
