When I tried the Mininet integration code example 1sw_demo.py, everything went smoothly, except closing the Mininet CLI.
After I typed in "exit" in the CLI, I got the following error messages.
Traceback (most recent call last):
  File "1sw_demo.py", line 114, in <module>
  File "1sw_demo.py", line 110, in main
  File "build/bdist.linux-x86_64/egg/mininet/net.py", line 574, in stop
  File "build/bdist.linux-x86_64/egg/mininet/link.py", line 506, in stop
  File "build/bdist.linux-x86_64/egg/mininet/link.py", line 499, in delete
  File "build/bdist.linux-x86_64/egg/mininet/link.py", line 205, in delete
  File "build/bdist.linux-x86_64/egg/mininet/node.py", line 441, in delIntf
KeyError: 'eth0'

I try to track down the error, and it looks like the interface of P4Host is the one with name "eth0". However, I am not able to fix this bug.
Does anyone experience the same error? How do you fix it?
