From: Thomas Huth <th...@redhat.com> The device can not be instantiated by the user and QEMU currently aborts when you try to use it:
$ x86_64-softmmu/qemu-system-x86_64 -device cpu-cluster qemu-system-x86_64: hw/cpu/cluster.c:73: cpu_cluster_realize: Assertion `cbdata.cpu_count > 0' failed. Aborted (core dumped) Since this is an internal device only, mark it with user_creatable = false.
