@staticmethod
def _DiagnoseByOS(rlist):

Remaps a per-node return list into a per-os per-node dictionary

Parameters
rlista map with node names as keys and OS objects as values
Returns
dict

a dictionary with osnames as keys and as value another map, with node UUIDs as keys and tuples of (path, status, diagnose, variants, parameters, api_versions) as values, eg:

  {"debian-etch": {"node1-uuid": [(/usr/lib/..., True, "", [], []),
                                  (/srv/..., False, "invalid api")],
                   "node2-uuid": [(/srv/..., True, "", [], [])]}
  }
def _GetQueryData(self, lu):
overrides ganeti.cmdlib.base.QueryBase._GetQueryData

Computes the list of nodes and their attributes.
