We asked about that to IBM via PMR. The answer is no - you cannot do nic bonding with the vswitch NIC. So I think the presentation is a little misleading on that page.

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.
