(meant to send this before, but kept forgetting...)

1) I thought modelName wasn't set for pci-root. Doesn't the above cause
a validation error in that case? (too early in the day, haven't tried it)

2) danpb made a nice new function to standardize/simplify errors of the
above type: virReportEnumRangeError().
