Hello GENI index Hello GENI index Hello GENI index

STEPS FOR SETTING UP

Using Omni to get physical PCs from ProtoGENI:
0. Get account: (Ignore this if you already have one)
Go to Request_GENI_Account for an emulab account and to join a GENI project.
Apparently you need to join a GENI project (which is created by PIs/GPOs/others who have permission to do so) in order to use GENI resources.

1. Prepare Omni
Here is a very good tutorial on setting up Omni environment: HelloOmni
Simply follow the tutorial to set up Omni.

2. Use Omni to create the topology:
Download the RSPEC from http://www.gpolab.bbn.com/experiment-support/TCPExampleExperiment/star.rspec
Next, we need to create this experiment using the RSPEC file:

Step 1. Create slice (use a unique name for your slice):

omni.py createslice <slice name>

Output should be something like the following (here I am using 'shufengTCP' as the sample slice name):

INFO:omni:Loading config file /Users/shuang/.gcf/omni_config
INFO:omni:Using control framework portal
INFO:omni:Created slice with Name shufengTCP, URN urn:publicid:IDN+panther:ShufengProject+slice+shufengTCP, Expiration 2013-05-08 21:17:05
INFO:omni: ------------------------------------------------------------
INFO:omni: Completed createslice:

  Options as run:
		framework: portal
		project: ShufengProject

  Args: createslice shufengTCP

  Result Summary: Created slice with Name shufengTCP, URN urn:publicid:IDN+panther:ShufengProject+slice+shufengTCP, Expiration 2013-05-08 21:17:05
 
INFO:omni: ============================================================

Step 2. Renew Slice (to make sure that your reservation does not expire before you finished your experiment, renew the slice to a specific time):

omni.py renewslice shufengTCP 20130509

Output:

INFO:omni:Loading config file /Users/shuang/.gcf/omni_config
INFO:omni:Using control framework portal
INFO:omni.pgch:Requesting new slice expiration '2013-05-09T00:00:00'

INFO:omni: ------------------------------------------------------------
INFO:omni: Completed renewslice:

  Options as run:

INFO:omni: ============================================================

Step 3. Create Sliver using star.rspec:

omni.py createsliver -a pg-utah shufengTCP star.rspec

Output:

INFO:omni: ============================================================

Note: When dealing with specific slivers, we need to add "-a pg-utah" to specify which aggregate manager we want to use (i.e., from where we want to reserve the resources). In our case here, we are using utah aggregate.

OK. After this point, we are ready to log on to the nodes and do our experiments! :-)

Using GENI Portal to get virtual machines from instaGENI:
0. GET GENI Portal Account
As usual, get a GENI Portal account via: Portal Main Site
Here is a very good tutorial on setting up GENI Portal account: Setup_Portal_Account

1. Prepare Omni by following this tutorial: HelloOmni
As a result, if you have already installed omni, all u need to do now is to do "omni-configure.py -f portal"
Apparently GENI Portal also uses Omni to control and manage GENI resources.

Very Important: using omni-configure.py -f portal will over-write ~/.ssh/geni_key and ~/.ssh/geni_key.pub. The result is, user can not login the reserved nodes using their omni keys (the original geni_key pair)
So, the simplest way to deal with this is, over-write the public/private keys. i.e., type 'Y' when prompt asks whether you want to replace the two files. Then use portal credentials to reserve resources.

2. Using GENI Portal to create the star topology

Step 1. Log in to your Portal account, and then create a slice using the "create slice" button. Note that you should give your slice a unique name. Here I used "shufengPortalTCP"
Step 2. Click your newly created slice, choose "add resources"

Step 3. Pick TCP Assignment - Virtual Machine in the drop-down box right to "Choose Resources"

The rspec file that is used can be found at http://www.gpolab.bbn.com/experiment-support/TCPExampleExperiment/star-vm.rspec

And choose an Aggregate, in our case, we choose "GPO instaGENI", then click "Reserve Resources"
This particular RSPEC file will reserve a 5 virtual machines forming a star topology as described earlier.

Step 4. If there is no error(s), the output should be as follows. Note that at this point the nodes are not ready yet.

Step 5. Go back to the slice page and wait until the slivers are ready.
Since we reserved our nodes from GPO instaGENI, we only need to click the "get status" button on GPO instaGENI column.
A note of "READY" with green background means the slivers are ready. (Do not forget to renew your slice after it is ready). See:

Step 6. Click "Details" button to get the detailed information, including the ways to login each nodes and then start to do your experiment!

Using Omni to get virtual machines from ExoGENI:
0. Get account: (Ignore this if you already have one)
Go to Request_GENI_Account for an emulab account and to join a GENI project.
Apparently you need to join a GENI project (which is created by PIs/GPOs/others who have permission to do so) in order to use GENI resources.

1. Prepare Omni
Here is a very good tutorial on setting up Omni environment: HelloOmni
Simply follow the tutorial to set up Omni.

2. Use Omni to create the topology:
Download the RSPEC from http://www.gpolab.bbn.com/experiment-support/TCPExampleExperiment/star-exo-vm.rspec

  • Note: If we compare the RSPEC we used here to reserve nodes from ExoGENI with the RSPEC we used here to reserve nodes from InstaGENI, we can find the following difference:
    • slivertype. For InstaGENI, it is emulab-openvz; For ExoGENI, it is m1.small. In fact, there are a handful of virtual machine types available for users to choose from. Check out this Link
    • disk_image. For InstaGENI, the user does not need to specify a disk_image, it automatically chooses a default one (a version of Fedora Core). For ExoGENI, the user have to specify one. Again, we have a handful of choices, see this link.
    • xml header.

Next, we need to create this experiment using the RSPEC file:

Step 1. Create slice (use a unique name for your slice):

omni.py createslice <slice name>

Output should be something like the following (here I am using 'shufengTCP' as the sample slice name):

INFO:omni:Loading config file /Users/shuang/.gcf/omni_config
INFO:omni:Using control framework portal

INFO:omni: ============================================================

Step 2. Renew Slice (to make sure that your reservation does not expire before you finished your experiment, renew the slice to a specific time):

omni.py renewslice shufengTCP 20130516

Output:

INFO:omni: ============================================================

Step 3. Create Sliver using star-exo-vm.rspec:
Here we used eg-gpo as the aggregate manager because we want to reserve resources from ExoGENI.
Any aggregate manager name that starts with eg indicates that it is an ExoGENI aggregate. For more aggregate manager names you can check out ~/.gcf/omni_config

omni.py createsliver -a eg-gpo shufengTCP star-exo-vm.rspec

INFO:omni: Completed createsliver:

  Options as run:

  Args: createsliver shufengTCP star-exo-vm.rspec

  Result Summary: Got Reserved resources RSpec from bbn-hn-exogeni-net-11443-orca 
INFO:omni: ============================================================

The above output shows the reserved nodes: pc73, pc81, pc55, pc47, pc84 and how they are connected. In this case, pc73 is the central node of the star topology.
Alternatively, you can use the following command to show the reserved nodes as well as ways to login:

readyToLogin.py shufengTCP -a eg-gpo

The result is something like the following:

INFO:omni: ============================================================

Note: When dealing with specific slivers, we need to add "-a eg-gpo" to specify which aggregate manager we want to use (i.e., from where we want to reserve the resources). In our case here, we are using ExoGENI Rack at GPO.
