0xF6 indicates that the VSWITCH type does not match how the guest has *previously* initialized its NIC. That is, you have, say, a layer 3 (IP) VSWITCH and the guest initialized its virtual NIC to "layer 3". Then you uncouple the guest from the VSWITCH, delete and re-define the VSWITCH as "layer 2" (ETHERNET) and re-couple. When the guest re-initializes as "layer 2" you get the 0xF6. Once a vNIC has a "personality", you must delete and re-define it to change the personality.
