This is all good stuff, except that the calls to error () should take
the conn (virConnectPtr) as first argument if conn is available, which
it is here.  So +1 if that change is made.

Hi Rich,

Thanks for the quick review.

I'll be happy to fix all of the uses of error -- and similar wrapper
functions -- but in a separate patch.  However, note that this is a
general problem: the vast majority of uses of error (at least in that
file) currently use NULL as the first parameter, even when there's a
usable "conn" in scope.

Yup, those are all bugs.

Even worse in xen_internal.c where we'd need some major restructuring to pass conn to all the places where it's needed.

Oh well.

Rich.
