Just to be sure - you looked in both the dom0 and domU syslog? Maybe you could
just try to reduce the MTU to 1490 for dom0 and domU and see if it works
better. I experienced quite a few "it sometimes works almost" type of network
problems in the past (not related to xen) and some of them were MTU related (->
tunnels, pppoe, ...).

The other problem I had with xen were scheduling problems that caused a domain
to almost freeze when another one was highly active. This made a large rsync
from domU->dom0 impossible and resulted in a loss of the network connection. I
solved this by executing a
xm sched-sedf ${DOMAIN} 0 0 0 1 1
for all domains including dom0. But I doubt that this is related to your
problem...
Thanks,
Michael
