# =====================================================================
# 
# This script is to generate ospf configuration for the VMs
# that has XORP installed, and start xorp process. 
#
# The script first to get the network configuration information, 
# such as virtual interfaces (neither eth0 nor lo), hostname, etc. 
# 
# Secondly, the script will start xorp process in the VM
