The main reason we added auto hibernate for vm is for dumb users, when they shut down the host machine without closing the virtual machine, it can do it without user input.
Also, when we support single app mode, if there is no apps running in a vm, it will be auto hibernate. and it saved time to start a vm app, of course --- On Sun, 1/17/10, Alexey Eremenko <[email protected]> wrote: From: Alexey Eremenko <[email protected]> Subject: Re: [vbox-dev] VMLite XP Mode for VirtualBox released To: [email protected] Date: Sunday, January 17, 2010, 10:29 AM 11.c. Well... Frankly I do not see any use-cases for per-VM settings... I have tried to configure some VMs to save state, some to shut down and some to "ask". This soon became a nightmare... . I started to afraid to push "close" button because I wasn't sure what will happen next ... will it close? save state ? ask? or the VM will blow up? extremely anti-intuitive workflow... Basically I recommend to have this feature in Global only, like in "11.a". In some cases having "ACPI shutdown" results in broken behavior... in cases if the guest OS does not support it. (XP installed with standard PC HAL, stucked VM, other OSes...) This brings me to a conclusion that ACPI powerdown should be used with caution or not at all... NOTE: The physical ACPI power supply allow PC to hard shutdown if the power button is being pressed for 5 seconds exactly for this reason. Unless smart mechanism can be developed for VMs, I recommend removing this option as from the GUI as dangerous. (either remove this option, or after 2 clicks allow user to choose.. "ask" for action) 11.d. "ACPI shutdown" often fails with the error that VM is currently paused, and it actually brings the VM into "pause" mode at the same time. -- -Alexey Eromenko "Technologov" _______________________________________________ vbox-dev mailing list [email protected] http://vbox.innotek.de/mailman/listinfo/vbox-dev
