Integrated unit tests fail in cinder due to default volume type not found

[Dirk Mueller]

Running

nosetests cinder/tests/integrated/test_volumes.py

on master fails with:

  File "/data/dmueller/src/Cloud/cinder/cinder/tests/integrated/test_volumes.py", line 108, in test_create_and_delete_volume
    self.assertEqual('available', found_volume['status'])
AssertionError: 'available' != u'error'
    "'available' != u'error'" = '%s != %s' % (safe_repr('available'), safe_repr(u'error'))
    "'available' != u'error'" = self._formatMessage("'available' != u'error'", "'available' != u'error'")
>> raise self.failureException("'available' != u'error'")

which is due to (according logs):

cinder.volume.volume_types: ERROR: Default volume type is not found, please check default_volume_type config: Volume type with name fake_vol_type could not be found.

Have you created the volume-type and associated the same witholume backend name because your volume creation expecting the same.

Actually, the test would pass even with exception.VolumeTypeNotFoundByName(volume_type_name=name), but the main problem is:
cinder.scheduler.filters.capacity_filter: ERROR: Free capacity not set: volume node info collection broken.
cinder.scheduler.manager: ERROR: Failed to schedule_create_volume: No valid host was found.

The 'bug' is introduced in this commit:

    Merge "Allow create_volume() to retry when exception happened"

Before this commit the test was passing despite VolumeTypeNotFoundByName exception.

I tried running tests, and everything went well. Am I missing something?

This was fixed by a recent commit that changed the default scheduler in the testsuite to 'chance'
