# This script configure IP alias(es) inside VE for SuSE-9
#
# Parameters are passed in environment variables.
# Required parameters:
#   IP_ADDR       - IP address(es) to add
#                   (several addresses should be divided by space)
# Optional parameters:
#   VE_STATE      - state of VE; could be one of:
#                     starting | stopping | running | stopped
#
# this should set up networking for SuSE-based VE
