Maybe you need to execute these commands before creating network
Example:
ADMINID=`openstack project list | grep admin | awk '{print $2}'` PHYSNET0='physnet0'
openstack network segment range create ${PHYSNET0}-a --network-type vlan --physical-network ${PHYSNET0} --minimum 400 --maximum 499 --private --project ${ADMINID}
