Errors about multiple networks pollutes functional test output

[Jay Pipes]

Running the Nova functional tests locally, I consistently get around a dozen or so of these in the output:

Captured stderr:

    NetworkAmbiguous: Multiple possible networks found, use a Network ID to be more specific.

They don't affect the result of the test, so it's nothing more than an annoyance, but would be nice to fix.

Hi Jay, can you please tell me how I can reproduce this issue? I run "sudo tox -e py27" on nova and I can't find any NetworkAmbiguous exception.
my plan is to find all test cases threw this exception and catch the exception in these test cases. what do you think?

Hi Jin Li!

You need to run tox -efunctional to run the functional tests. You'll see the output in there :)

Best,

Hi Jay,
I use this version of nova : 0a2700e4e69996f1df080e34c11cb7ae448ad938
and run tox -efunctional in home directory of nova, there are some stderr but none of them is NetworkAmbiguous. am I missing any steps? do I need to have devstack running to do functional test?

I will attach me test result below for you convenience.

This is several years old and this issue no longer exists.
