 2. Add persistent bitmaps to disks
    { "execute": "transaction", "arguments": { "actions": [ {"type":"block-dirty-bitmap-add", "data": { "node": "drive_image1", "name": "bitmap0","persistent":true}},{"type":"block-dirty-bitmap-add", "data": { "node": "drive_data1", "name": "bitmap0","persistent":true}},{"type":"block-dirty-bitmap-add", "data": { "node": "drive_data2", "name": "bitmap0","persistent":true}}]}}
{"return": {}}

 3. Query block info
    {"execute":"query-block"}
