(Get the code!)
I believe I faced this bug too on Xenial with kernel 4.10.0-26-generic on amd64. We use multiple multiqueue virtual adapters per VM so only partial connectivity loss occurs.
With systemtap I can see that on host last_used_event from patch equals to 0x0 on one of the queues, and guest receiving 0x1 as return value for that queue from __dev_queue_xmit which I beleve is NET_XMIT_DROP.
