I mean saving the guest vm states.
You can test it easily on windows XP guest. (I use Vista/Windows 7 host).
(1) on guest: vboxcontrol guestproperty wait myprop
then close vm saving state
start vm, and
(2) on host: vboxmanage guestproperty set myprop 123
You will note that vm waiting process never returns.

Does hibernation mean ACPI hibernation here or saving the guest's state?
