when i shut down the os x host system while parallels is running, it is triggering the hibernation on the guest windows xp system. just before parallels does this, a script by parallels tools could be triggered. i have seen this possibility in the windows version of vmware workstation (vmware tools).
edit: here is a screenshot from vmware tools (in german) from a windows 2000 guest running under vmware fusion for mac. it has options for executing bat scripts on halting, resuming (even for startup and shutdown, i assume these scripts are ran at service level or something)
