Just Try it might it will solve your problem. Team both physical adapters to one logical. Share this logical adapter with host OS and guest os. Probably, this result in some glitches and other strange things, so final reliability will be _lower_ then useing network cards separately, due to software trobles. However, part of them can be fixed . Add two server NICs to server. Team 2 integrated NICs into one team for host OS, team two new NICs to another team for guest OS. You need server NICs (3Com, Intel, etc), as only their drivers support teaming. However, some vendors team drivers allow teaming with 3-rd party NICs, as long, as one of the cards in the team is from this vendor.
