This is a recipe to fix this error when importing to VMWare an OVA
file:
Download and install OVFTool (https://www.vmware.com/support/developer/ovf/)
Convert OVA to VMX using the command below (this will create example.vmx)
$ ovftool example.ova example.vmx
Note: If this command fails, try to re-run again adding the option --lax
so error on the version of the metadata is converted into a warning.
Now edit the VMX file and look for “virtualhw.version” parameter, change it ("10" is usually ok, but the actual value depends on your VMWare setup) and save the file.
virtualhw.version = "10"
Convert VMX back to OVA using the same command.
$ ovftool example.vmx example.ova
