Alex, I have trouble getting kvm smp support running. Turns out that qemu does a kvm run even on secondary CPUs which dont have a sane state (initial psw == 0) triggering some program faults. Architecturally these cpus are in the stopped state, so we should not do KVM_RUN. (these CPUs will be started by a SIGP restart later during the boot process)
This patch seems to help (it allows me to boot and use more than 1 cpu) --- a/cpus.c +++ b/cpus.c @@ -131,6 +131,10 @@ static void do_vm_stop(int reason) static int cpu_can_run(CPUState *env) { + if (env->halted) { + return 0; + } + if (env->stop) { return 0; } but it does not look like the right solution. What are the proper definitions for halted and stopped? Christian
