I would advise to not define 'artificial' names, i.e. such that cannot
be retrieved via a user-space interface on the host in order to make it
easier for systems management tools to figure out the right CPU model
in the future.
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.
