All these features are supposed to be handled by the call to
virDriverFeatureIsGlobal() placed right above the switch
statement, so group them together and add a comment. If any of
these features is actually encountered as part of the switch
statements, that means there's a bug in the driver and we should
error out.

Here you return an error without reporting an error.
Would virReportEnumRangeError be reasonable to use here?

Here you return an error without reporting an error.
Would virReportEnumRangeError be reasonable to use here?
Mh. While the error message ("Unexpected enum value N for virFoo") is
not too specific about this, virReportEnumRangeError() is usually
called when the provided value cannot be translated back to one of
the enum values; in this case it *can* be converted, it's just not
supposed to be encountered in the specific situation. Given the
subtly different semantics, I'm leaning towards not using that
helper.
Would something like
virReportError(VIR_ERR_CONFIG_UNSUPPORTED,
_("Global feature %d should have already been handled"),
feature);
work for you? I'd drop the comment of course.

Thanks! Pushed after squashing in the virReportError() calls and
tweaking the error message slightly.
