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) On Sun, Jan 17, 2010 at 8:44 PM, Huihong Luo <[email protected]> wrote: > > 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.
