Asked by Tuna


  I installed tacker on my controller node manually. I succeeded to start it, deploy a vnfd which were a sample on Tacker's Manual Installation page. (OpenWRT)

  When i try to create vnf, it stucks in ERROR status :

(tacker.log ERROR)
ERROR tacker.vnfm.plugin [-] VNF Create failed for vnf_id 47be08ca-b1ae-417b-9165-07cdf5ad12db

Hit the same, can't remember where I saw this workaround but it was a matter of adding this property in the VDU definition:
"user_data_format: RAW"


      type: tosca.nodes.nfv.VDU.Tacker
        user_data_format: RAW

Same issue, and add "user_data_format:RAW" to VDU definition can resolve it.

Can you help with this problem?
