*** Bug 861905 has been marked as a duplicate of this bug. *** Note that the patch was already acked for 6.3.z when it was first posted. Reproduced on qemu-kvm-0.12.1.2-2.295.el6_3.2.
Steps:
1. { "execute" : "__com.redhat_drive-mirror", "arguments" : { "device" : "drive-virtio-disk0", "target" : "/root/sn1", "format": "qcow2", "mode": "existing", "full" : false } }
{"error": {"class": "OpenFileFailed", "desc": "Could not open '/root/sn1'", "data": {"filename": "/root/sn1"}}}
2. in hmp
(qemu) info block-jobs
Type mirror, device drive-virtio-disk0: Completed 0 of 0 bytes, speed limit 0 bytes/s
3.{ "execute": "transaction", "arguments": {'actions': [ { 'type': 'blockdev-snapshot-sync', 'data' : { 'device': 'drive-virtio-disk0', 'snapshot-file': '/root/sn1' } }] } }
{"error": {"class": "DeviceInUse", "desc": "Device 'drive-virtio-disk0' is in use", "data": {"device": "drive-virtio-disk0"}}}
Results:
1.(qemu) info block-jobs
Type mirror, device drive-virtio-disk0: Completed 0 of 0 bytes, speed limit 0 bytes/s
2.{"error": {"class": "DeviceInUse", "desc": "Device 'drive-virtio-disk0' is in use", "data": {"device": "drive-virtio-disk0"}}}
Verify on qemu-kvm-rhev-0.12.1.2-2.295.el6_3.4.x86_64.
Steps:
1. { "execute" : "__com.redhat_drive-mirror", "arguments" : { "device" : "drive-virtio-disk0", "target" : "/root/sn1", "format": "qcow2", "mode": "existing", "full" : false } }

{"return": {}}
Results:
after step1
(qemu) info block-jobs
No active jobs
after step2
(qemu) info block
