# This script helps setup services for running PaaS native, kvm or ovm tests.
# setup.sh -r -d <templates-dir> -s jee,javadb,mysql,oracle,apachemodjk,otd,lb native|kvm|ovm2|ovm3
# Examples:
#   1) Plain native setup
#      setup.sh native
#   2) Native with lb service
#      setup.sh -s lb native
#   3) KVM with jee service
#      setup.sh -t /kvm/images -s jee kvm
#   4) KVM with jee,javadb,apachemodjk services
#      setup.sh -t /kvm/images -s jee,javadb,apachemodjk kvm
#   5) OVM with jee service
#      setup.sh -t /ovm/templates -s jee -p pool1 ovm2
#   6) OVM with jee,otd services
#      setup.sh -t /ovm/templates -s jee,otd -p pool1 ovm2
#   7) Recreate domain1 before setting up
#      setup.sh -r native
