I start 10 VMs(windows xp), then running geekbench tool on them, about 2 days, one of them was reset, I found the reset operation is done by int kvm_cpu_exec(CPUArchState *env) { ... switch (run->exit_reason) ... case KVM_EXIT_SHUTDOWN: DPRINTF("shutdown\n"); qemu_system_reset_request(); ret = EXCP_INTERRUPT; break; ... } KVM_EXIT_SHUTDOWN exit reason was set previously in triple fault handle handle_triple_fault(). What causes the triple fault?
