Public bug reported:

When doing a list with the os-host extension the host name attribute is
host_name in all other cases the host name attribute is host.

E.g. when doing a list operation a result like this is expected:

{"hosts": [
  {"zone": "internal", "host_name": "awesome-node1", "service": "compute"}]}

When doing a describe of the same host:

{"host": [{"resource": {"project": "(total)", "memory_mb": 193278, "host": "awesome-node1", "cpu": 48, "disk_gb": 98}},
          {"resource": {"project": "(used_now)", "memory_mb": 13312, "host": "awesome-node1", "cpu": 6, "disk_gb": 20}},
          {"resource": {"project": "(used_max)", "memory_mb": 12288, "host": "awesome-node1", "cpu": 6, "disk_gb": 20}},
          {"resource": {"project": "de59ee29134b4980bbb77608347ae08a", "memory_mb": 12288, "host": "awesome-node1", "cpu": 6, "disk_gb": 20}}]}

This is confusing at best.

It has already caused some problems in the official client library.
