看着像老乡啊，一般虚拟机正常情况下是可以关机成功的，有时候关机后会显示正在关机，那么你再关一次也可以成功关机
还有一种特别的情况，虚拟机本身卡死，进行强制关机操作，有概率变成僵尸进程（父进程是1的这种），这种情况只能重启宿主机了，我碰到过几次，没有解决方案（通常出现在高IO操作情况下导致的超时）

Subject: [ovirt-users] cannot stop vm normally
Sometimes, some vm failed to stop it by press the shutdown button on the management portal, it will show such message in log: shutdown of vm *** failed.

And I want to know:
1. why cannot shutdown it normally ?
2. what difference between the shutdown and power off ? (For example, what are the different signals sent to the QEMU process)

Thanks.
