Further, if 'z900' was the host CPU model, then it should also be accepted in kvm mode in order to behave as on x86. This can be deferred to a future point in time. Having said this, I have no idea whether 'z900' would be a correct choice for a CPU model or not. -- Mit freundlichen Grüßen/Kind Regards Viktor Mihajlovski IBM Deutschland Research & Development GmbH Vorsitzender des Aufsichtsrats: Martin Jetter Geschäftsführung: Dirk Wittkopp Sitz der Gesellschaft: Böblingen Registergericht: Amtsgericht Stuttgart, HRB 243294
