When we shutdown/reboot a guest using agent-mode, if the guest itself blocks infinitely, libvirt would block in qemuAgentShutdown() forever. Thus, we set a timeout for shutdown/reboot, from our experience, 60 seconds would be fine. Signed-off-by: Zhang Bo <oscar.zhangbo@huawei.com> Signed-off-by: Wang Yufei <james.wangyufei@huawei.com>
