tox -e tests
tests create: /vdsm/.tox/tests
tests installdeps: nose==1.3.7
tests installed: nose==1.3.7
tests runtests: PYTHONHASHSEED='1382456816'

tox uses random seed on each run, exposing bad code assuming order
of unordered things.

To repeat tests failures, you probably want to use the same seed,
this can be done like this:

    tox -e tests --hashseed SEED

See https://docs.python.org/2/using/cmdline.html#envvar-PYTHONHASHSEED
