我正在使用 Debian 9 和 KVM 作为虚拟机管理程序的 VM 中运行 Ubuntu 18.04（桌面），但运行时virsh shutdown BS-MS01我收到一条消息，说域正在关闭，但 VM 实际上仍然位于登录屏幕上。
我已确认acpid已安装并在来宾上运行：
ms01admin@BS-MS01:~$ sudo service acpid status
● acpid.service - ACPI event daemon

我什至已经添加了acpi=forcegrub，但没有运气让它工作，而且我已经没有想法了。
有人有什么想法吗？
答案1
似乎电源按钮的事件没有自动创建，不知道为什么？
在这里创建了一个新的事件处理程序：
sudo nano /etc/acpi/events/powerbtn
有了这些参数：
event=button/power
action=/sbin/poweroff
然后重新启动服务：
sudo service acpid restart
现在我可以关闭访客了！
