> actually use them ? Yes, that's the "virtualization". If you only have standard CPUs in the z/VM LPAR, we call it "simulation". You will be able to define a virtual CPU as a zIIP or a zAAP. I should point out that, as with z/OS, if you add a zIIP or a zAAP to a z/VM LPAR, you do not owe IBM any additional z/VM license charges. > Any idea what the overhead is likely to be. No more than for any other virtual CPU, but I don't think we can make any definitive statements at this point as z/VM 5.3 is still under development, and performance analysis is on-going.
