@AparnaKarve Can you address the Travis failure? Thanks.

[AparnaKarve]

@lfu The Travis failure is related to the fact that ManageIQ/manageiq#17364 is still not merged.
Once it gets merged, we should re-run Travis here, and bring it to green.

@AparnaKarve @lfu Please see failing tests after core PR merged.

@gmcculloug @lfu Fixed the tests

@abellotti This should be good to go

[abellotti]

are we ok with the changed signature coming back from the method/thus REST API ? Aren't current callers be broken ?

[gmcculloug]

Only caller today would be ManageIQ/manageiq-v2v#618.

@AparnaKarve Can you confirm that you are expecting these keys to change?

[AparnaKarve]

@abellotti As Greg mentioned above, v2v is the only caller.

In ManageIQ/manageiq-v2v#618 I have taken into account the changed signature coming back from the API/method.

[AparnaKarve]

@abellotti Can we merge this today?
Without this PR and ManageIQ/manageiq-v2v#618, v2v would be broken in the nightly build tonight.
