The tests are now failing with

failed to set up volume 'lv1': __init__() got an unexpected keyword argument 'stripe_size'

because we don't have the latest version of blivet (which adds support for setting stripe_size for LVs), but the test should be skipped in this case. I am not sure why the version based skipping isn't working here correctly, I am looking into this.

The skipping of the stripe size test case works correctly, this was actually a bug -- I was passing the stripe_size option even if stripe size wasn't specified so all the test cases were failing with old blivet. This should be fixed now.
