Simple Layer 2 Experiment Using the GENI Portal

Part I/Step 2: Obtain Resources: create a slice and reserve resources

Image Map

Instructions

Now that you are a member of a project, you can create a slice and reserve resources.

1. Create a slice

  1. Go to the Home tab.
  2. Press the Create Slice button for this project.
  3. As a slice name use the slice name on your worksheet (the slice name should be of the form portal##), you can leave the description empty and press Create Slice

Figure 1.1 Create a new slice.

2. Reserve Virtual Machines at Two Aggregates

For this tutorial, we have manually reserved a VLAN (a layer 2 circuit) from a GENI rack in Utah (Utah InstaGENI) to a GENI rack in Massachusetts (GPO InstaGENI).

Now reserve a virtual machine (VM) connected to each end of the manually configured VLAN.

Warning In order to pace the creation of the VMs, please only reserve your two VMs when you are given a "blinking ball" by the tutorial instructor.

First, reserve a VM on the Utah end of the VLAN. This node will be refered to as the "client".

  1. Go to the Slice page and press the Add Resources button. Complete the form as shown in the picture on the left and press the Reserve Resources button. Reserving the node at the aggregate may take a minute or two. Do not reload the page or press the back button while waiting.

Second, reserve a virtual machine connected to the Massachusetts end of the manually configured VLAN. This node will be refered to as the "server".

  1. Go back to the Slice page and again press the Add Resources button. Complete the form as shown in the picture on the left and press the Reserve Resources button. Again, this may take awhile. Do not reload the page or press the back button while waiting.

3. Check Whether Virtual Machines are Ready to be Used

It takes some time for the VMs to boot. Check to see if they are up.

  1. Return to the Slice page. Press the Get All button in the aggregate table.
Status at both aggregates
Figure 3.1 Get the status at all aggregates.
  1. The rows for GPO InstaGENI and Utah InstaGENI should say READY against a green background and look as shown on the left.
  2. If one of the rows do not say READY, press the Get Status button on that row periodically until it does.
Status at both aggregates
Figure 3.2 Resources at Utah InstaGENI and GPO InstaGENI are green to indicate they are ready.
