### Method Details

`lookupEffectiveGuestPolicy(instance, body=None, x__xgafv=None)`

    Lookup the effective guest policy that applies to a VM instance. This
    lookup merges all policies that are assigned to the instance ancestry.

    Args:
      instance: string, Required. The VM instance whose policies are being looked up. (required)
      body: object, The request body.
        The object takes the form of:

    { # A request message for getting the effective guest policy assigned to the
          # instance.
        "osVersion": "A String", # Version of the OS running on the instance. The OS Config agent only
            # provides this field for targeting if OS Inventory is enabled for that
            # VM instance.
        "osShortName": "A String", # Short name of the OS running on the instance. The OS Config agent only
            # provides this field for targeting if OS Inventory is enabled for that
            # instance.
        "osArchitecture": "A String", # Architecture of OS running on the instance. The OS Config agent only
            # provides this field for targeting if OS Inventory is enabled for that
            # instance.
      }

      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:
