# Common Configuration
# ====================

# Set fixed and floating range here so we can make sure not to use addresses
# from either range when attempting to guess the IP to use for the host.
# Note that setting FIXED_RANGE may be necessary when running DevStack
# in an OpenStack cloud that uses either of these address ranges internally.

die $LINENO "Could not determine host ip address. Either localrc specified dhcp on ${HOST_IP_IFACE} or defaulted"
