Comment 21 for bug 807893

with some grepping of parent callers, looks like the cpu is probably my issue

static void qemu_kvm_start_vcpu(CPUState *env)
{
    env->thread = qemu_mallocz(sizeof(QemuThread));
    env->halt_cond = qemu_mallocz(sizeof(QemuCond));
    qemu_cond_init(env->halt_cond);
    qemu_thread_create(env->thread, qemu_kvm_cpu_thread_fn, env);

    /* init the dynamic translator */
    cpu_exec_init_all(tb_size * 1024 * 1024);

.. etc

later on it does chroot/setgid/setuid
