Bug Description

When using tap network devices and it fails, qemu gives no information about what the problem is (permission denied, device busy or other), making debugging of such situations, especially for newbies, very difficult. The proposed patch just adds strerror() around the place, making it more friendly.

Michael's fix is good, but it got forgotten, probably because he has submitted it in the middle of a thread.

I'm going resubmit it again.
