I have been trying to save state of my virtualbox guest OS (XP) while my UPS is initiating a shutdown in the host OS (Windows 7 x64).
But the problem is during the shutdown initiation, the virtualbox pops up a dialog box for the guest OS (Save machine state,send shutdown signal,power off machine)
This dialog box prevents the shutdown process.
Is there any way I can make ALT+F4 to do Savestate of guest OS instead of popping up the dialog box?
*The ups software tries to close everything with ALT+f4
