Depending on your definition of "TCP/IP has been started" and your distribution, you can run some custom code in the ifup processing, or position a script from /etc/init.d to start at the appropriate moment. You can notify your vm or other Linux machine either by ping (tcpdump is one program you can use to detect it) or UDP: you can write a little code to log the particular even, or fetch a small file with tftp: xinetd can log the connection. For that matter, xinetd can log any connection: attempting to connect to any UDP port xinet is configured to listen to will do.
