From e79ccc88c3668567bf656cd0113ca46058ef8f00 Mon Sep 17 00:00:00 2001 Message-Id: From: Peter Krempa Date: Tue, 4 Feb 2020 15:08:11 +0100 Subject: [PATCH] tests: qemublock: Add synthetic snapshot+checkpoint test data MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a faked qemu output which would simulate scenario where libvirt would take a snapshot and checkpoint simultaneously. This is visible in libvirt-2-format node where bitmap 'c' appears, but bitmap 'b' which is active in the previous layer is not present.
