[vbox-dev] Auto-Close - VMLite XP Mode for VirtualBox released

[Alexey Eremenko]

I am not against auto hibernation.... In fact I find this feature
useful. I am against automatic "ACPI powerdown signal"...

Automatic settings can work, but:
1. provided it is global, not per-VM.
2. It should have the following feature set:
-save state (hibernate)
-power off
|--+ revert to latest snapshot (checkbox)
-ask for action

(remove ACPI signal, and add option to revert to latest snapshot)
