So the only real update we’ve had on this ESXi problem is that it’s a bug. But I can’t give you a KB to reference, because, well, there isn’t one. And we’re not alone in feeling some pain about this, as Erik Zandboer noted on his blog. So I guess at this stage we’ll seriously reconsider if and how we use host profiles in the environment and wait for the new version of ESXi. It’s underwhelming but there you go.
