Do you have by any change another gist on how to add a new NIC. Specially the case when adding the backinginfo. Currently I have with some issues with the VirtualEthernetCardDistributedVirtualPortBackingInfo complaining about the uuid of the distributedVirtualSwitch.uuid. I would be interested to see how you add the backinginfo. Perhaps I'll get something from it ;-) .

Nevertheless thanks for sharing.

Marc.

When I run this code, I get com.vmware.vim25.VirtualEthernetCardDistributedVirtualPortBackingInfo back as the class for getBacking, am I doing something wrong?
