Currently, there is one flag passed in during macvtap creation
(withTap) -- Let's convert this field to an unsigned int flag
field for future expansion.

The flag check could be fixed not to report in such cases, but it's easier just to check the flags for now. But it should be: virCheckFlags(0, -1);

You aligned only one value. Unless you object to it, I'll align them together without too many whitespaces. Other than that, it looks fine, ACK after 1.2.8, I'll push it with the changes mentioned after the release if you're OK with that. Martin
