That is by definition. Setting up layer2 LACP requires exclusivity for the OSA chpid. >2.

An OSA not answering port channeling frames is down as far as the inquiring side is concerned. >3. This seems to be the only way we could configure to support a >real switch failure. No, it can be done for example with Cisco VSS switch pairs, where the failover of the real switch box is a function of the VSS code. Other vendors may/may not have this feature, I am no networking guy. Now to your main question: how are you going to tell the two VSWITCHes involved the VNICs form a port channel? It does not even work with one VSWITCH (I tried) as VSWITCH has no port channeling other than to real OSA's. You can define two VNICs on one guest to the same VSWITCH and put Linux bonding to them, but only one VNIC will be used. The other one is useless and does not even have a role as failover as the first one can have no hardware failure to failover from.
