    5454GPO ProtoGENI user credentials used: lnevers@bbn.com used for Experimenter1, and lnevers1@bbn.com used for Experimenter2.
     55
    5556== Step 1. As Experimenter1, request !ListResources from Utah InstaGENI ==
    5657
    … …  
    9394
    9495== Step 4. Define a request RSpec for two VMs, each with a GPO Ubuntu image ==
     96
     97This test case could not be executed as originally planned, modifications were required.  Using advertised Ubuntu or FreeBSD images is not supported for sliver_type emulab-openvz. The containers con only support Fedora.  This does not allow the execution of step 4 in the IG-EXP-2 InstaGENI Single Site test case, found at [http://groups.geni.net/geni/wiki/GENIRacksHome/AcceptanceTests/InstageniAcceptanceTestsPlan#IG-EXP-2:InstaGENISingleSiteAcceptanceTest]
     98
     99Two options available:
     100
     101    (a) Modify step 4 to assume default image is used (Fedora15).
     102
     103    (b) Modify step 4 to assume a raw-pc is used to load the custom image, which duplicates later step 12 in the procedure.
     104
     105Choosing option (a) for the execution of step 4, which implies that RSpec is modified to use default OpenVZ image.
     106
    95107Test is also to request a publically routable IP address and public TCP/UDP port mapping for the control interface on each node

    99 Using advertised Ubuntu or FreeBSD images is not supported for sliver_type emulab-openvz. This does not allow the execution of step 4 in the IG-EXP-2 InstaGENI Single Site test case, found at [http://groups.geni.net/geni/wiki/GENIRacksHome/AcceptanceTests/InstageniAcceptanceTestsPlan#IG-EXP-2:InstaGENISingleSiteAcceptanceTest]

    101 Two options available:
    102 
    103     (a) Modify step 4 to assume default image is used (Fedora15).
    104 
    105     (b) Modify step 4 to assume a raw-pc is used to load the custom image, which duplicates later step 12 in the procedure.

    108109
    109110== Step 5. Create the first slice ==
     111
    110112Created the slice as follows:
    111113{{{
    112 $ ./src/omni.py createslice ig-exp2-2vm
     114$ omni.py createslice IG-EXP2-exp1
    113115}}}
    114116
    115117== Step 6. Create a sliver in the first slice, using the "modified" RSpec as defined in step 4 ==
    116 Created a 2 VM sliver, checked sliver status for completion, and determine assigned host from the sliverstatus sliver manifest:
    117 {{{
    118 $ ./src/omni.py createsliver -a insta-utah ig-exp2-2vm --api-version 2 -t GENI 3 ./instarspec/insta-2vm-v3.rspec
    119 $ ./src/omni.py sliverstatus -a insta-utah ig-exp2-2vm --api-version 2 -t GENI 3 -o
    120 $ egrep "hostname|port" ig-exp2-2vm-sliverstatus-boss-utah-geniracks-net-protogeni-xmlrpc-am-2-0.json
    121 }}}
    122 The RSpec used to create the sliver ig-exp2-2vm can be found [http://groups.geni.net/geni/browser/trunk/GENIRacks/InstaGENI/Spiral4/RSpecs/AcceptanceTests/IG-EXP-2 here]
     118
     119Created a 2 VMs sliver using the RSpec [http://groups.geni.net/geni/browser/trunk/GENIRacks/InstaGENI/Spiral4/RSpecs/AcceptanceTests/IG-EXP-2/IG-EXP-2-exp1.rspec IG-EXP-2-exp1.rspec]: 
     120{{{
     121$ omni.py createsliver -a ig-utah IG-EXP-2-exp1 --api-version 2 -t GENI 3 IG-EXP-2-exp1.rspec
     122}}}
     123
     124Checked sliver status to verify that the node allocation and provisioning has been completed, by checking the 'pg_status' is 'ready':
     125{{{
     126 $ omni.py sliverstatus -a ig-utah IG-EXP-2-exp1 --api-version 2 -t GENI 3
     127}}}
     128
     129Once the nodes are allocated and provisioned, determine the assigned hosts that are assigned to the experiment:
     130{{{
     131 $ omni.py listresources -a ig-utah IG-EXP-2-exp1 --api-version 2 -t GENI 3 -o
     132 $ egrep "hostname|port" IG-EXP-2-exp1-rspec-utah-geniracks-net-protogeni.xml   
     133   <login authentication="ssh-keys" hostname="pc3.utah.geniracks.net" port="30778" username="lnevers"/> 
     134   <login authentication="ssh-keys" hostname="pc3.utah.geniracks.net" port="30779" username="lnevers"/>
