  <title>How to Record Bluescreen Information from Windows Guests</title>
  
  <body>
    <p>
        When Windows guests run into a kernel crash, they display a
        bluescreen error. Depending on how Windows is configured, the
        information will remain on the screen until the machine is
        restarted or it will reboot automatically. During installation,
        Windows is usually configured to reboot automatically. With
        automatic reboots, there is no chance to record the bluescreen
        information which might be important for problem determination.
