Cannot open Xterm for switch at the mininet CLI

[hamkuu]

I'm trying to run the test for INT Reference Application described on routing-fail-over-test

The mininet topology has the following nodes:

mininet> nodes
available nodes are:
h1 h2 h3 h4 leaf1 leaf2 spine1 spine2

I can open an Xterm terminal for h1 by typing

mininet> xterm h1

However, by typing

mininet> xterm leaf1

The mininet prompt returned without any error message, but I cannot see any Xterm popup window.

What might be the problem in this case?

Can you send me your environment information? I use Ubuntu 14.04. Also, run the following on the host operating system to see if this opens an xterm on the Docker node.

sudo docker exec mininet-leaf1 xterm
