How can I get FreeNAS to respond to libvirt shutdown requests

I have a KVM VM of FreeNAS 0.7.1 Shere (revision 5127) running on Ubuntu Server 10.04 and I'm unable to convince the VM to shutdown from the host

virsh shutdown freenas

I would expect this to send some ACPI? trigger to the VM and FreeNAS then do what it's told.

I'm not a FreeBSD fundi so I don't really know what packages or processes to poke to get this running. I have tried to convince powerd to run, but the VM cpus don't have the required freq entry

Is this possible? Ideally I'd like to be able to stop the host without having to manually deal with shutting down the VM.

The only way I've found to get this working is to pass the -no-kvm-irqchip parameter to kvm. The easiest way to do this in libvirt is to create a wrapper script (eg /usr/local/bin/kvmbsd)

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

And change the emulator line in your libvirt configuration to point to the wrapper script.

/usr/local/bin/kvmbsd

This allows me to cleanly shutdown (but not reboot - this doesn't appear to be implemented in libvirt/kvm yet) my freebsd based vms.
