Como posso fazer com que o FreeNAS responda a solicitações de desligamento do libvirt?

Question

Eu tenho uma VM KVM do FreeNAS 0.7.1 Shere (revisão 5127) em execução no Ubuntu Server 10.04 e não consigo convencer a VM a desligar do host

virsh shutdown freenas

Espero que isso envie alguma ACPI? disparar para a VM e FreeNAS, em seguida, fazer o que é dito.

Eu não sou um fundi do FreeBSD, então eu realmente não sei quais pacotes ou processos usar para fazer isso funcionar. Eu tentei convencer o powerd a rodar, mas o cpus da VM não tem a entrada necessária freq

Isso é possível? Idealmente, eu gostaria de poder parar o host sem ter que lidar manualmente com o desligamento da VM.

    

Answer 1

A única maneira que encontrei para fazer isso funcionar é passar o parâmetro -no-kvm-irqchip para kvm. A maneira mais fácil de fazer isso no libvirt é criar um script wrapper (por exemplo, / usr / local / bin / kvmbsd)

#!/bin/sh
exec /usr/bin/kvm "$@" -no-kvm-irqchip

E altere a linha do emulador em sua configuração libvirt para apontar para o script wrapper.

/usr/local/bin/kvmbsd

Isso me permite desligar (mas não reinicializar - isso não parece ser implementado no libvirt / kvm ainda) meu vms baseado no FreeBSD.

    

Answer 2

Verifique se a VM está habilitada para ACPI, é o que um desligamento limpo faz - envia uma chamada ACPI. No entanto, existem outras maneiras, como criar scripts de um comando de desligamento por meio do ssh, usando o monitorCommand sendKey para enviar um pressionamento de tecla projetado para iniciar um desligamento, executando um comando "destroy" (essencialmente um plug pull), etc.
