Some error messages contain ambiguous representations of the 'node-name'
parameter. This can be particularly confusing when exchanging QMP
messages (C = client, S = server):
C: {"execute": "block_resize", "arguments": { "device": "my_file", "size": 26843545600 }}
S: {"error": {"class": "GenericError", "desc": "Cannot find device=my_file nor node_name="}}
^^^^^^^^^
This error message suggests one could send a message with a key called
'node_name':
C: {"execute": "block_resize", "arguments": { "node_name": "my_file", "size": 26843545600 }}
^^^^^^^^^
but using the underscore is actually incorrect, the parameter should be
'node-name':
S: {"error": {"class": "GenericError", "desc": "Parameter 'node_name' is unexpected"}}
This behavior was uncovered in bz1651437, but I ended up going down a
rabbit hole looking for other areas where this miscommunication might
occur and changing those accordingly as well.
