1. Look in /var/log for dmesg, kernel.log or kmsg. These files cn be
created by syslog and one of them might contain this information.

2. Use dmesg command and grep it like this: dmesg | grep "Initial Network"

I have seen articles about using console port to redirect kernel messages
from VM to host. You may want to look for details in google. I don't
remeber the ugly details...
