Right, but if the VM is configured properly, this is not so much of a problem.
For 2k3 and presumably also 2k8 there's a trivial fix: enable the group policy
option "Shutdown: Allow system to be shut down without having to log on" under
"Computer Configuration" -> "Windows Settings" -> "Security Settings" -> "Local
Policies" -> "Security Options" and the system will react to ACPI
shutdown/reboot requests no matter if there is someone logged on or not.
