The x86 kvm kernel module limits guest cpu count to 16, but theuserspace pc definition says 255 still, so kvm_create_vcpu will fail for that reason with -smp > 16 specified. This patch causes qemu-kvm to exit in that case. Without this patch other errors get reported down the road and finally a segfault occurs.
