It's a misunderstanding, I never wished to imply a lack of information
existed on how to use the feature. Actually it was the page that led
to testing type 'volume' with RBD backends and finding out it didn't
work yet. Hence supporting other pool type would not require an update
to the documentation, which was my message. Although it's true we
could mention what's not supported yet in that area.

Understood, working on new tests and a proper implementation.
It turns out I overlooked a lot of problems.

Indeed. The lack of 'secrettype' prevented migrations because of this,
and your post came in timely.

Thanks John
