我有一台运行在 Ubuntu Server 10.04 上的 FreeNAS 0.7.1 Shere（修订版 5127）的 KVM VM，我无法让主机关闭 VM
virsh shutdown freenas
我希望它能向 VM 发送一些 ACPI？触发器，然后 FreeNAS 会执行它所要求的操作。
我不是 FreeBSD 的粉丝，所以我不知道要使用什么包或进程才能运行它。我曾尝试让 powerd 运行，但 VM CPU 没有所需的频率条目

这可能吗？理想情况下，我希望能够停止主机，而不必手动关闭虚拟机。
答案1
我发现实现此目的的唯一方法是将 -no-kvm-irqchip 参数传递给 kvm。在 libvirt 中执行此操作的最简单方法是创建一个包装器脚本（例如 /usr/local/bin/kvmbsd）
#!/bin/sh
exec /usr/bin/kvm "$@" -no-kvm-irqchip
并更改 libvirt 配置中的模拟器行以指向包装器脚本。
/usr/local/bin/kvmbsd
这使我能够干净地关闭（但不重新启动 - 这似乎尚未在 libvirt/kvm 中实现）基于 freebsd 的 vms。
答案2
确保虚拟机已启用 ACPI，这就是干净关机所做的 - 发送 ACPI 调用。但是还有其他方法，例如通过 ssh 编写关机命令脚本、使用 monitorCommand sendKey 发送旨在启动关机的按键、运行“销毁”命令（本质上是拔出插头）等。
