Dear Colin,

My config for this domain is here:

kernel = "/usr/lib/xen-4.0/boot/hvmloader"
builder = "hvm"

name = ''
memory = 512
vcpus = 1
cpus = '1-3'
disk = [
vif = [ 'mac=00:16:3e:00:04:01,bridge=eth0' ]

vnc = 1
boot = "c"
stdvga = 1
localtime = 0

hpet = 1
acpi = 1
apic = 1
pae = 1
usb = 0

on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"

But as I read the documentation, on_poweroff means what to do when the domain powers itself off. But for me it seems, that xen sends a halt to the freebsd domain, exactly as if I issue a
# halt
In that case, the domain does halt, and shows that the system is halted, and press any key to reboot. Unfortunately I dont have a freebsd on real hardware, so I dont know if issue a halt on that does it powers itself off.

But when inside the domain, and I issue poweroff, it works as expected, I guess it sends an acpi poweroff to xen, and then tha virtual machine gets stopped.

I am looking for a solution to be able to shutdown my freebsd 9.0 amd64 xen hvm
domain from outside, from the host. Precisely, when the host is halted, it
issues an
# xm shutdown domain --halt --wait

to the domain, and the domain does not poweroff. It behaves as if I issue a halt
inside of it, and not a poweroff. Is there a way to have it power down itself?

That sounds like a Xen configuration issue ("poweroff behaviour"?) rather than a
FreeBSD issue to me.
