------- Additional Comments From niv@xxxxxxxxxx  2005-08-19 00:00 -------
A tcp connection request from remote host (*.86) to domu (*.114) shows 
domU getting the SYN and responding with its SYN/ACK, but 86
doesn't get it, and keeps retrying till failure.

[root@dom0 log]# tcpdump -n -i xen-br0 host 9.53.94.114
tcpdump: WARNING: xen-br0: no IPv4 address assigned
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

So outgoing packets on the bridge from domU seem to be getting hosed.
