From 0b27b655b1bac480186ce80457113cd5dc34e6a1 Mon Sep 17 00:00:00 2001 From: Peter Krempa Date: Thu, 12 Dec 2019 13:50:55 +0100 Subject: [PATCH] tests: qemublock: Add test case for detecting bitmaps as we create snapshots Add test data gathered from a run of qemu after creating bitmaps and snapshots together in various combinations. The following sequence of commands was used to achieve the configuration: virsh checkpoint-create-as VM --name a virsh snapshot-create-as VM --disk-only virsh snapshot-create-as VM --disk-only virsh checkpoint-create-as VM --name b virsh checkpoint-create-as VM --name c virsh snapshot-create-as VM --disk-only virsh checkpoint-create-as VM --name d virsh snapshot-create-as VM --disk-only virsh checkpoint-create-as VM --name current Note that VM was restarted after these operations to allow renumbering of the bitmaps in a more human-readable way.
