Unittest openvswitch.test_ovs_tunnel cannot run alone

[Zhongyue Luo]

The test hangs when running the command below

$ ./run_tests.sh openvswitch.test_ovs_tunnel

[yong sheng gong (gongysh)]

I have no such problem:
gongysh@gongysh-ThinkPad-T420:~/git/quantum$ ./run_tests.sh openvswitch.test_ovs_tunnel

I'll check with my env tomorrow. It just stalled in my case.

It hangs for me where a pre-created venv is present. When I hit ctrl-c it dumps a traceback which indicates it was stuck in some rpc connection retry attempt:

The initial problem was that test was actually trying to setup RPC connection to real rpc backend.

This commit adds fake amqp impl in the test configuration and thus is solving the problem. https://github.com/openstack/quantum/commit/38379bf3c5594848fdf5cd4ad3580b399ba04dc9
