This adds tests for live snapshots, both through the single snapshot command, and the transaction group snapshot command. The snapshots are done through the QMP interface, using the following commands for snapshots: Single snapshot: { 'execute': 'blockdev-snapshot-sync', 'arguments': { 'device': 'virtio0', 'snapshot-file':'...', 'format': 'qcow2' } }" Group snapshot: { 'execute': 'transaction', 'arguments': {'actions': [ { 'type': 'blockdev-snapshot-sync', 'data' : { 'device': 'virtio0', 'snapshot-file': '...' } }, { 'type': 'blockdev-snapshot-sync', 'data' : { 'device': 'virtio1', 'snapshot-file': '...' } } ] } } Signed-off-by: Jeff Cody <jcody@redhat.com> --- tests/qemu-iotests/085 | 192 +++++++++++++++++++++++++++++++++++++++++++++ tests/qemu-iotests/085.out | 55 +++++++++++++ tests/qemu-iotests/group | 1 + 3 files changed, 248 insertions(+) create mode 100755 tests/qemu-iotests/085 create mode 100644 tests/qemu-iotests/085.out
