@micafer Thank you for your contribution!

Unfortunately the old path is no longer covered by tests. Are the OpenStack versions that need the old path still supported? If yes, we need somehow two tests to test the two paths. If it can be removed, then let's do that!

I don't have other issues with your code. Thanks!

Hi @pquentin ,
I have added a new test to cover the old path.

[pquentin]

Thanks! Merged in trunk. ✨ Can you please close the LIBCLOUD issue? I can't do that myself.

LIBCLOUD issue closed!
