I downloaded an OVA file from SDN-Hub ( original link infested by Adware. Do NOT use it. Instead use archived version), and used VMWare Player 11 to import it.sdnhub.org/tutorials/sdn-tutorial-vm/
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 VirtualBox and export it again using OVF format 1.0.
Then VMware was happy importing the machine, and it just works fine.
