If you are using a FreeBSD amd64 kernel with Xen PV drivers installed, shutdown behavior is controlled by the PV "control" driver. This driver notices updates to the "control/shutdown" node in the XenStore and is supposed to act accordingly. For a reboot or power off event, it simply calls shutdown_nice(RB_POWEROFF|RB_HALT), or shutdown_nice(0) as appropriate. If you can capture the value of the shutdown node in the XenStore, it should be pretty easy to debug this. -- Justinhelp
