我在 Debian 7.1 主机上安装了 KVM 并开始运行，主机上有两个 Debian 7.1 客户机和一些 Windows XP 客户机。当我使用命令“virsh shutdown”或点击 virt-manager 中的关机按钮关机时，Debian 客户机进入 pmsuspended 状态。
我可以正确关机的唯一方法是通过 ssh 进入那些客户端并输入“shutdown -h now”命令。
在两个 Debian 客户机上我都安装并运行了以下软件包：
ii acpi 1.6-1 amd64 displays information on ACPI devices
ii acpi-fakekey 0.140-5 amd64 tool to generate fake key events
ii acpi-support 0.140-5 all scripts for handling many ACPI events
ii acpi-support-base 0.140-5 all scripts for handling base ACPI events such as the power button
ii acpid 1:2.0.16-1+deb7u1 amd64 Advanced Configuration and Power Interface event daemon
以下是我的 Debian 客户机上的 acpid 事件：
:/etc/acpi/events$ cat powerbtn-acpi-support
event=button[ /]power
action=/etc/acpi/powerbtn-acpi-support.sh
/etc/acpi/powerbtn-acpi-support.sh
#!/bin/sh
# This script initiates a shutdown when the power putton has been
# pressed. Loosely based on the sample that ships with the acpid package.
# If the acpid sample is present as a real config file (as it was in earlier
# versions of acpid), we skip this script. (Purging and reinstalling acpid
# resolves this situation, or simply deleting /etc/acpi/events/powerbtn.)
if [ -f /etc/acpi/events/powerbtn -o -f /etc/acpi/events/powerbtn.dpkg-bak ] ; then
logger Acpi-support not handling power button, acpid handler exists at /etc/acpi/events/powerbtn or /etc/acpi/events/powerbtn.dpkg-bak.
exit 0
fi
[ -e /usr/share/acpi-support/policy-funcs ] || exit 0
. /usr/share/acpi-support/policy-funcs
if CheckPolicy; then
exit 0
fi
if [ -x /etc/acpi/powerbtn.sh ] ; then
# Compatibility with old config script from acpid package
/etc/acpi/powerbtn.sh
elif [ -x /etc/acpi/powerbtn.sh.dpkg-bak ] ; then
# Compatibility with old config script from acpid package
# which is still around because it was changed by the admin
/etc/acpi/powerbtn.sh.dpkg-bak
else
# Normal handling.
/sbin/shutdown -h -P now "Power button pressed"
fi
更新
上周安装了新的 Debian 客户虚拟机，没有出现关机问题。有问题的 Debian 虚拟机已从 VirtualBox 移至 KVM，并且是较旧的 Debian 7 安装。
答案1
我最近通过安装 acpid 和编辑解决了当前 Ubuntu 上的问题/etc/acpi/events/powerbtn包含装有操作=/sbin/poweroff。
答案2
我在旧的 vmware 映像上遇到了同样的问题，我将其转换为 libvirt/KVM。它经历了许多 Debian 版本升级。我尝试了所有常规方法，检查客户机中是否启用了 acpi，并在 /etc/acpi/events 中创建了事件脚本。但都不起作用。最后我清除了该软件包。
aptitude 清除 acpid
然后我还删除了我自己创建的其余脚本。然后我进行了全新的数据包安装
aptitude 安装 acpid
安装过程中可以看到的内容是：
将安装以下新软件包：acpi-support-base{a} acpid consolekit{a} libck-connector0{a} libpam-ck-connector{a} libpolkit-gobject-1-0{a}
奇怪的、新的依赖关系......而且它有效！
希望这对你有用！
