Open Stack

Hi,

Yes, it's very surprising. I manage to obtain your error by doing the
operations manually (compute and guest are ubuntu 12.04 and devstack
deployment).

Another interesting thing is that, in my case, with multi-backend enabled,
tempest tells me everything is right:

/opt/stack/tempest# nosetests -sv
tempest.tests.volume.test_volumes_actions.py
nose.config: INFO: Ignoring files matching ['^\\.', '^_', '^setup\\.py$']
tempest.tests.volume.test_volumes_actions.VolumesActionsTest.test_attach_detach_volume_to_instance[smoke]
... ok
tempest.tests.volume.test_volumes_actions.VolumesActionsTest.test_get_volume_attachment
... ok

----------------------------------------------------------------------
Ran 2 tests in 122.465s

OK


I don't think that error is linked to the distribution. With my
configuration, if I remove the multi-backend option, attachment is possible.

Regards,
Jérôme
