I use KDE on a Debian-based Linux distro. I run Windows 7 in a virtual machine on a secondary desktop. Often times during the day, I hear the Windows startup sound. I would like to know why Windows just reset itself. I use the VM mostly for software development, other than MS Security Essentials, Firefox, Anki, and Visual Studio there are no other software installed on the machine.
Is there some sort of log that I might check to see why the latest reset was performed? The VM is connected to the internet so System Updates are possible, but I find malware to be extremely unlikely.
EDIT: Looking in the system log, there is no log entry for the shutdown. Only after the restart does this appear in the System Log:
The previous system shutdown at 11:17:48 AM on 5/18/2012 was unexpected.
The entries prior to that are dated about a quarter of an hour earlier, when I turn on the VM. So whatever is causing the reset is not giving the OS time to write to the logs. I would suspect the power, but this is a virtual machine!
