KVM来宾停止运行，使主机kvm退出。

Question

我在kvm中运行Linux。当我在来宾中以根用户身份发出halt命令时，来宾最终会使用内核日志消息System halted.停止运行。但是，kvm主机进程继续运行。它能在停下来的时候退出吗？

这看起来像是一个相关的讨论：http://comments.gmane.org/gmane.comp.emulators.kvm.devel/107972

一个相关的讨论，但它是关于阻止客人离开主人，而不是从内部：http://ubuntuforums.org/showthread.php?t=1066940

一个类似的bugreport，没有任何有意义的响应：https://bugs.launchpad.net/ubuntu/+source/linux/+bug/967049

我的内核没有编译ACPI，所以我增加了支持，但它仍然不会停止。这就是我在启动时得到的信息：

[    0.311211] ACPI: PCI Interrupt Link [LNKC] enabled at IRQ 11
[    0.312637] virtio-pci 0000:00:03.0: PCI INT A -> Link[LNKC] -> GSI 11 (level, high) -> IRQ 11
[    0.315049] ACPI: PCI Interrupt Link [LNKD] enabled at IRQ 10
[    0.316472] virtio-pci 0000:00:04.0: PCI INT A -> Link[LNKD] -> GSI 10 (level, high) -> IRQ 10
[    0.318858] ACPI: PCI Interrupt Link [LNKA] enabled at IRQ 10
[    0.320254] virtio-pci 0000:00:05.0: PCI INT A -> Link[LNKA] -> GSI 10 (level, high) -> IRQ 10

ACPI内核配置：

# CONFIG_ACPI_PROCFS_POWER is not set
# CONFIG_ACPI_EC_DEBUGFS is not set
# CONFIG_ACPI_PROC_EVENT is not set

更新：poweroff使用一个启用了ACPI的内核(例如上面的内核配置)。halt仍然不起作用。

Answer 1

尝试运行halt -p

-p告诉主机在关机后关闭电源。

具体来说，halt的手册页声明：

-p, --poweroff
       Instructs the halt command to instead behave as poweroff.

Answer 2

你试过使用：

 # shutdown -h now

有时，ACPI守护进程没有运行，您可能也需要检查它。
