Hi, based on my naive and unsuccessful tests to add a CPU that was not declared on qemu startup via "-smp", I assume that the monitor command "cpu_set" lacks some range check, right? Or is it allowed to add CPUs dynamically that way? Then there would be some bug in qemu-kvm's (next branch) CPU management.
