From 87467eae37e9b4727152292e09acead3ba3c95ed Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Fri, 7 Jul 2017 09:22:14 -0300 Subject: [PATCH] qmp: Include 'abstract' field on 'qom-list-types' output A client may be interested in getting the list of both abstract and non-abstract types. Instead of requiring them to make multiple queries with different filter arguments, just return an 'abstract' field in 'qom-list-types'. In addition to the new test code for validating this field, update the abstract-interfaces test case to query for all 'interface' subtypes (including abstract ones), and to look at the 'abstract' field directly.
