Hi Ingo,

Have you tried without enabling "ndisc" (QoS) and "ipv6" ?
They are both present in your log and i assume you are using a bridged network 
config ?
You wouldn't be the first to stumble over a more generic kernel network bug
while using Xen, due to less well tested combinations.
So it's worth testing if plain ipv4 and no QoS works.
