why would you want to channel bond two vnics going to the SAME vswitch? Chances of a software vnic failure are pretty remote, and may affect all vnics anyway. I can see bonding two vnics coupled to two vswitches. David Kreuter

I don't see how NIC bonding has anything to do with Link Aggregation. I don't see any reason why you wouldn't be able to form a bond out of two virtual NICs COUPLEd to the same VSWITCH. From the Linux perspective, they look just like any other eth? device.
