The best way to do this is probably with netconsole.  This gets your
kernel to spit out the printk messages over the network so you can use
netcat on another machine to see the latest messages before the kernel
hangs.  I don't know if there's a problem with doing this on a virtual
machine.  Google around or read the kernel docs to see how this works.
