Comment 13 for bug 1073241

Yong,

The logging itself is not preventing drivers from loading. Sorry if I was unclear. The problem is that messages that the stevedore library, which ml2 uses for loading drivers, tries to log are not logged. If a driver cannot be loaded, the details on why it couldn't be loaded should be logged but instead are lost. During development, syntax errors, missing abstract method implementations, etc., are common reasons a driver cannot be loaded, and the trace info that stevedore tries to log would be really helpful.
