Last week I was migrating some servers from ESX 3.02 to a vSphere 5 cluster, after importing the the exported VM’s I received this error message:

The device or operation specified at index ’2′ is not supported for the current virtual machine version ‘vmx-04′.  A minimum version of ‘vmx-06′ is required for this operation to succeed.

A general system error occurred: Invalid fault

Solution:

The VMware Converter I used was version 4.3.0 build-292238

After installing VMware Converter 5.0.0 build-470252 I was able to start the import virtual machine in the new vSphere 5 cluster

The import finished successfully
