This is caused by the recent eventlet release:

    https://pypi.python.org/pypi/eventlet/0.18.0

In particular, this issue: "Handle blocking I/O errors in GreenSocket".

    https://github.com/eventlet/eventlet/issues/274
    https://github.com/eventlet/eventlet/commit/bc4d1b5d362e5baaeded35b1e339b9db08172dd2

To reproduce (assuming your dev env is using eventlet 0.18.0):

    tox -e functional nova.tests.functional.api_sample_tests.test_cloudpipe.CloudPipeSampleTest

Comment added upstream here: https://github.com/eventlet/eventlet/issues/290

Upstream bug: https://github.com/eventlet/eventlet/issues/291

[Diana Clarke (diana-clarke)]

Fixed in https://pypi.python.org/pypi/eventlet/0.18.1

[Davanum Srinivas (DIMS) (dims-v)]

0.18.0 was blocked in g-r and 0.18.1 works fine - so fixed upstream

[Markus Zoeller (markus_z) (mzoeller)]

As we use the "direct-release" model in Nova we don't use the
"fix comitted" status for merged bug fixes anymore. I'm setting
this manually to "fix-released" to be consistent.
