6:04 p.m.
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.

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）

Shitdown needs integration and cooperation from the VM OS. Did you install the
qemu-guest-agent , is it working properly ?

You should possibly find more information in vdsm.log about why it has
failed.
2. what difference between the shutdown and power off ? (For
example,
what are the different signals sent to the QEMU process)
Power off forcibly stops the VM. From the VM point of view it is similar
to pulling out a power cord from bare metal computer.
Shutdown delivers a request to the guest OS (which may or may not
satisfy the request). If you see an error it means there was a problem
communicating the request to the guest. The request is delivered either
using a guest agent (if one is installed) or using an ACPI event.
Hope this helps,
Tomas
