Getting Started With GENI - Part 2 Exercise 2

Image Map

1. Design the Experiment

  1. In today's experiment you will use resources at the aggregate listed on your worksheet.

3. Obtain Resources

You can use Flack or Omni to create your slice and allocate resources. The instructions here assume you are using Flack.

3.1 Find your slice

On your portal home page, find the project (GEC17). Click on the project name and find the slice you created earlier in this tutorial.

3.3 Reserve Two Virtual Machines at One Aggregate

The Portal is integrated with a tool, Flack, which allows you to draw topologies of GENI resources and then reserve them.

  1. On the Slice tab, press the Flack button. Flack will open in a new tab.
Launch Flack

  1. Wait for Flack to load. You should see: your username, the slice name, and a list of aggregates. Flack should look like the picture to the right.

  1. Find the aggregate listed on your worksheet.
  2. Click the VM box next to that aggregate and drag it onto the canvas.
  3. Repeat the above step. You should now see two VM boxes on the canvas.
  4. Now click near one of the VM boxes on the canvas, then click and drag towards the other VM. Release when you reach the other VM. You should now see a line and a box representing a link connecting the two VMs.
  5. The canvas should now look like the picture on the right.
  6. To edit the name of each VM, click the i in the circle.

  1. In the field at the top, replace "VM" with "client".
  2. If you are using an ExoGENI rack, set the "Sliver Type" to "EC2Small".
    ExoGENI ExoGENI allows you to reserve machines of various sizes. We will use small ones for this tutorial to conserve resources.

  1. Now click on the "Interfaces and Links" (middle tab with the "link" symbol").
  2. Enter the Desired IP Address for this node.
  3. Enter the Desired Mask of
  4. Then Press "Apply" at the bottom of the screen.
  5. Repeat the above six steps for the second VM, labeling it "server" and setting the server's Desired IP Address.

  1. Click the Submit button near the bottom of the page. When prompted, confirm you want to actually reserve resources.

3.4 Check Whether Virtual Machines are Ready to be Used

  1. After clicking the Submit button, wait for the canvas to turn green. (This may take awhile.)
  2. The canvas should now look like the picture on the right.
Resources are ready
