No, that does not work. On a different host, that has an dedicated IPMI 
NIC, I have a dropdown with the alternatives Dedicated, Share and Failover 
but on this I only have a grayed out Share, no alternatives and no choices. 
So this seems to be something hardwired in the MB.

I will do a PR on the hit stuff.
