Hi, originally I was using your driver and attaching it to either eth0 or the bridge I have, br0. I was getting problems with ARP, 9vx could see the traffic but the host could not see the guest. Also 9vx would eventually crash due to freeing memory that was in use. Is the raw socket driver meant to be attached to a unused device? Both eth0 and br0 were being used by the host system.
