The combo of Hyper-V, VMQ, Emulex and lost network connectivity has been a nightmare for a long time. We have tried it all and the ONLY solution that works has been to disable VMQ, which sucks.

But there is light in the tunnel, they are working on new firmware so stay tuned for that. The new firmware is about to released mid-July 2014.
