I don't see why not. I've done this before and it used to work just 
fine. These are two different controllers that work independently and I 
do it so that the VM(s) could have its own NIC to work with as I believe 
the virtual network bridge interferes with other network activity.

If we assume that both ports give rise to problems because they run 
without teaming/link aggregation (which I think not) then there wouldn't 
be any issues if I only used one network port. I have tried with only 
one port and the issues are considerably worse in that configuration.
