Comment 2 for bug 1881231

In step 3 I used following commands:
on primary vm console:
{"execute": "drive-mirror", "arguments":{ "device": "colo-disk0", "job-id": "resync", "target": "nbd://169.254.66.10:9999/parent0", "mode": "existing","format":"raw","sync":"full"} }

// till the job ready
{ "execute": "query-block-jobs" }

{"execute": "stop"}
{"execute": "block-job-cancel", "arguments":{ "device": "resync"} }

{'execute': 'human-monitor-command', 'arguments': {'command-line': 'drive_add -n buddy driver=replication,mode=primary,file.driver=nbd,file.host=169.254.66.10,file.port=9999,file.export=parent0,node-name=replication0'}}
{'execute': 'x-blockdev-change', 'arguments':{'parent': 'colo-disk0', 'node': 'replication0' } }
{'execute': 'migrate-set-capabilities', 'arguments': {'capabilities': [ {'capability': 'x-colo', 'state': true } ] } }
{'execute': 'migrate', 'arguments': {'uri': 'tcp:169.254.66.10:9998' } }
{ "execute": "migrate-set-parameters" , "arguments":{ "x-checkpoint-delay": 10000 } }
