s390_cpu_realize_sysemu() runs some checks for the TCG accelerator, previous to creating the vCPU. s390_realize_cpu_model() also does run some checks for KVM. Move the sysemu call to s390_realize_cpu_model(). Having a single call before cpu_exec_realizefn() will allow us to factor a verify_accel_features() handler out in a pair of commits. Directly pass a S390CPU* to s390_cpu_realize_sysemu() to simplify.

That has nothing to do with CPU models and is, therefore, completely misplaced ... :/
Or what am I missing? -- Cheers, David / dhildenb
