安装了acpi的KVM客户不会关机。

Question

我安装了KVM，并在我的Debian7.1主机上使用了两个Debian7.1客户和一些Windows客户。当我使用命令'virsh关机‘或在virt管理器中按下关机按钮时，Debian来宾会进入go悬挂状态。

唯一能正确关闭的方法是对这些来宾进行ssh，并键入“立即关闭-h”命令。

在这两位debian来宾上，我都安装并运行了这些包：

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

以下是我对我的debian客人所发生的事情：

:/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

上周安装了一个新的Debian客户VM，它没有关闭问题。确实存在问题的Debian是从VirtualBox迁移到KVM的，是Debian 7的旧安装。

Answer 1

最近，我通过安装acpid并编辑/etc/acpi/events/powerbtn来包含action=/sbin/poweroff，从而解决了当前Ubuntu上的问题。

详细说明

Answer 2

我在一个旧的vmware映像上也遇到了同样的问题，我将其转换为libvirt/KVM。它经历了许多Debian版本的升级。我尝试了所有常用的方法，检查是否在来宾中启用了acpi，并在/etc/acpi/events中创建了事件脚本。什么都没用。最后我清除了包裹。

智能清除acpid

然后，我还删除了我自己创建的其余脚本。然后我做了一个新的包安装

智能安装

在安装过程中可以看到的是：

将安装以下新软件包: acpi-support-base{a} acpid控制台{a} libck-connector0{a} libpam-ck-连接器{a} libpolkit-gobject-1-0{a}

奇怪的新的依赖..。而且起作用了！

希望这对你有用！
