From 15ebf0b3bcbca92d0d63a67be3deee35572f1f00 Mon Sep 17 00:00:00 2001 From: Miroslav Rezanina Date: Thu, 6 Dec 2018 10:03:56 +0100 Subject: [PATCH 16/34] iotests: Test migration with -blockdev RH-Author: Kevin Wolf Message-id: <20181128092947.24543-3-kwolf@redhat.com> Patchwork-id: 83181 O-Subject: [RHEL-7.7/7.6.z qemu-kvm-rhev PATCH 2/2] iotests: Test migration with -blockdev Bugzilla: 1633536 RH-Acked-by: Max Reitz RH-Acked-by: Stefan Hajnoczi RH-Acked-by: Laurent Vivier Check that block node activation and inactivation works with a block graph that is built with individually created nodes. RHEL: Disabled query-migrate call on the destination; this returns only an empty object in 2.12. Changed reference output for Python 2 (we lack the compatibility patches from upstream that make the output independent from the Python version).
