What about instead of inventing new error code re-use the old VIR_ERR_OPERATION_FAILED? Something like we have in virDomainObjListAddLocked:
if (STRNEQ(vm->def->name, def->name)) {
virUUIDFormat(vm->def->uuid, uuidstr);
virReportError(VIR_ERR_OPERATION_FAILED,
_("domain '%s' is already defined with uuid %s"),
vm->def->name, uuidstr);
goto error;
}
