Diagnosing these failures is infuriatingly difficult as the UI
generally hides the true reason for the failure.

This is not correct. The logs are stored on the host performing the
conversion. This is completely unrelated to the SPM role and which host
it is can be even specified by the user in the import dialog. Maybe the
default host (unless changed by the user) is the same as the SPM host,
but that would have to be checked and even than I would refrain from
mentioning it in the docs. Which host is performing the conversion can
be checked under 'Events' tab in the oVirt administration.

Actually it can get little bit complex and two VDSM hosts can be
involved. But I don't think we should complicate the matters here.

These errors would be in the engine.log mentioned below.
