I downloaded an OVA file from SDN-Hub, and used VMWare Player 11 to import it.
It came out with this error message:
Error while converting to a virtual machine:
Line 96:Unsupported element 'StorageItem'
Line 105:Unsupported element 'StorageItem'
Line 114:Unsupported element 'EthernetPortItem'
It's weird, because I downloaded the same file a few months ago in my other computer, and it worked well.
Seems the problem is related to the OVF format, the virtual machine was exported using OVF 2.0
What I did to import it to vmware was to import the sdn-hub vm into virtual box and export it again using OVF format 1.0.
Then vmware was happy importing the machine, and just works fine
