I am running OS/390 2.10 on a z10 native. You must have the z990 
compatibility feature installed. You can only run 31bit and you must not 
try to set the date/time during the IPL. IOCP must be done on HMC. I am 
using newer DS8000 so flash-copy does not work because the OS does not 
recognize the DS8000 as flashable.


I have been tempted to try it on a z114 (as I have a spare one), but 
just have not bothered yet.

I think it depends on the processor being emulated by the z/VM system.
