  12 # https://svn.planet-lab.org/wiki/SfaDeveloperDummyTutorial#RunningSFAinDummyflavour
  13
  14 # 1) list all the resources  of bonfire from sfa's point of view
  15 # python -c 'import bonfire; print bonfire.bonsources()'
  16
  17 # 2) retrieve the url, the name and the key that will currently use by sfa for a compute N°3656 located at fr-inria
  18 # python -c 'import bonfire; print bonfire.rsa_user_bonfire("fr-inria", "3656")'

  21 # python -c 'import bonfire; print bonfire.new_user_slice()'
  22
  23 # 4) changing the status to running status for the experiment 2911
  24 # python -c 'import bonfire; print bonfire.provisioning("2911")'
  25

  27 # python -c 'import bonfire; print bonfire.stop_vm("fr-inria", "3756")'

  29 # 6) allocation : create an experiment bonfire with slice information
  30 # python -c 'import bonfire; print bonfire.allocate("nlebreto", "nlebreto", "tdes", "125", "topdomain.dummy.nicolasi", "https://api.integration.bonfire.grid5000.fr/experiments")'
