3. Obtain Resources
3.3 Launch jFed to Reserve Two Virtual Machines at One Aggregate
The Portal is integrated with a tool, jFed, which allows you to draw topologies of GENI resources and then reserve them.
If you are on a Mac, you must us the Firefox (recommended) or Safari browsers.
- On the Slice tab, press the jFed button. jFed will open in a new window.

- From the "Select testbed" drop-down, pick the aggregate assigned to you. DO NOT forget to do this
- Select the node and press the "Duplicate" button. You should now see two node boxes on the canvas.
- Now click near one of the node boxes on the canvas, then click and drag towards the other node. Release when you reach the other node. You should now see a line and a box representing a link connecting the two nodes.
- The canvas should now look like the picture on the right.
