This feels a rather dirty to me - we shouldn't be trying to second
guess whether a filename might be a URI.

I think we should not be passing URIs to the virFileSanitizePath in
the first place.  Based on what you say about usage, it sounds like
the call to virFileSanitizePath needs to be pushed down into the
storage backend drivers themselves.

Daniel
