  VnfInstance:
    description: >
      This type represents a VNF instance. It shall comply with the provisions defined in table 6.5.3.57-1.
      
      NOTE: Clause B.3.2 of ETSI GS NFV-SOL 003 provides examples illustrating the relationship among the 
            different run-time information elements (CP, VL and link ports) used to represent the connectivity 
            of a VNF.

      NOTE 1: Modifying the value of this attribute shall not be performed when conflicts exist between the 
              previous and the newly referred VNF package, i.e. when the new VNFD is changed with respect to 
              the previous VNFD in other aspects than merely referencing to other VNF software images. 
              In order to avoid misalignment of the VnfInstance with the current VNF's on-boarded VNF Package, 
              the values of attributes in the VnfInstance that have corresponding attributes in the VNFD shall 
              be kept in sync with the values in the VNFD.
      NOTE 2: ETSI GS NFV-SOL 001 specifies the structure and format of the VNFD based on TOSCA specifications.
      NOTE 3: VNF configurable properties are sometimes also referred to as configuration parameters applicable 
              to a VNF. Some of these are set prior to instantiation and cannot be modified if the VNF is instantiated, 
              some are set prior to instantiation (are part of initial configuration) and can be modified later, 
              and others can be set only after instantiation. The applicability of certain configuration may depend 
              on the VNF and the required operation of the VNF at a certain point in time.
      NOTE 4: It is possible to have several ExtManagedVirtualLinkInfo for the same VNF internal VL in case of a 
              multi-site VNF spanning several VIMs. The set of ExtManagedVirtualLinkInfo corresponding to the same 
              VNF internal VL shall indicate so by referencing to the same VnfVirtualLinkDesc and externally-managed 
              multi-site VL instance (refer to clause 6.5.3.59).
      NOTE 5: Even though externally-managed internal VLs are also used for VNF-internal connectivity, they shall not 
              be listed in the "vnfVirtualLinkResourceInfo" attribute as this would be redundant.

          eclared in the VNFD if auto-scaling and/or auto-healing are supported by the VNF:
          - isAutoscaleEnabled: If present, the VNF supports auto-scaling. If set to true, 
            auto-scaling is currently enabled. If set to false, auto-scaling is currently 
            disabled.
          - isAutohealEnabled: If present, the VNF supports auto-healing. If set to true, 
            auto-healing is currently enabled. If set to false, auto-healing is currently 
            disabled.
