[vbox-dev] VbglR3GuestPropWait() not working well after hibernation

[Huihong Luo]

Any progress on this? If the bug fix takes long, we may need to implement differently.
 
We are using guest property to launch guest applications from host, however this bug prevents it working once vm is saved to states (vm is hibernated). Seems there are some states related are not saved or recovered correctly.

Michael,
 
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.

Hello Huihong,

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