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.
